The 2009 Influenza Pandemic: Selected Legal Issues

Summary
On June 11, in response to the global spread of a new strain of influenza, the World Health
Organization (WHO) raised the level of influenza pandemic alert to phase 6, which indicates the
start of an actual pandemic. This change reflects the spread of the new influenza A(H1N1) virus,
not its severity. Although currently the pandemic is of moderate severity with the majority of
patients experiencing mild symptoms and making a rapid and full recovery, this experience could
change. This report provides a brief overview of selected legal issues including emergency
measures, civil rights, liability issues, and employment issues.
There are a number of emergency measures which may help to contain or ameliorate an infectious
disease outbreak. The Public Health Service Act, the Federal Food, Drug, and Cosmetic Act, and
the Stafford Act contain authorities that allow the Secretary of Health and Human Services or the
President to take certain actions during emergencies or disasters. While the primary authority for
quarantine and isolation in the United States resides at the state level, the federal government has
jurisdiction over interstate and border quarantine. The federal government also issues
recommendations regarding such activities as school closures and vaccination programs. States
and local governments have the authority to initiate emergency measures such as mandatory
vaccination orders and certain nonpharmaceutical interventions such as school closures, which
may lessen the spread of an infectious disease. The International Health Regulations adopted by
the WHO in 2005 provide a framework for international cooperation against infectious disease
threats.
The use of these emergency measures to contain the 2009 influenza pandemic may raise a classic
civil rights issue: to what extent can an individual’s liberty be curtailed to advance the common
good? The U.S. Constitution and federal civil rights laws provide for individual due process and
equal protection rights as well as a right to privacy, but these rights are balanced against the needs
of the community.
Liability issues may become particularly important during the 2009 influenza pandemic. The
Public Readiness and Emergency Preparedness Act limits liability with respect to the use of
countermeasures for pandemic flu or other public health threats. A patchwork of federal and state
laws generally protect volunteers, which may include volunteer health professionals (VHPs),
under certain circumstances. Laws also provide liability protections specifically for VHPs.
Questions relating to employment are among the most significant issues presented by an
influenza pandemic, since, if individuals fear losing their employment or their wages, compliance
with public health measures such as social distancing and isolation or quarantine may suffer. It
would seem possible for a court to conclude that the isolation or quarantine of individuals during
a pandemic serves the public good and that the termination of individuals who are isolated or
quarantined violates public policy. Employees may also have some job protection under the
Family and Medical Leave Act.

The 2009 Influenza Pandemic: Selected Legal Issues

Introduction
On June 11, in response to the global spread of a new strain of influenza, the World Health
Organization (WHO) raised the level of influenza pandemic alert to phase 6, the highest level,
which indicates the start of an actual pandemic.1 This change in alert level reflects the spread of
the new virus, not its severity. In late April 2009, human cases of infection with a novel influenza
A(H1N1) virus were identified. Since then, the virus has become widespread. Although currently
the pandemic is of moderate severity with the majority of patients experiencing mild symptoms
and making a rapid and full recovery, the virus and its effects may change over time.2 This report
provides a brief overview of selected legal issues including emergency measures, civil rights,
liability issues, and employment issues.
Emergency Measures
Emergency Authorities3
Public Health Emergency Authorities
In response to public health threats, the Secretary of the Department of Health and Human
Services (HHS) can provide a considerable degree of assistance to states through the Secretary’s
general, non-emergency authorities. For example, upon the request of a state health official, and
without the involvement of the President, the Centers for Disease Control and Prevention (CDC)
can provide financial and technical assistance to states for outbreak investigation and disease
control activities. These activities are carried out under the Secretary’s general authority to assist
states at 42 U.S.C. §§ 243(c) and 247b.
There are also a number of authorities in the Public Health Service (PHS) Act that allow the
Secretary of HHS to take certain actions in the face of a “public health emergency.” The principal
authority is in Section 319 of the PHS Act, 42 U.S.C. § 247d(a), which states that
If the Secretary determines, after consultation with such public health officials as may be
necessary, that—(1) a disease or disorder presents a public health emergency; or (2) a public
health emergency, including significant outbreaks of infectious diseases or bioterrorist
attacks, otherwise exists, the Secretary may take such action as may be appropriate to
respond to the public health emergency, including making grants, providing awards for
expenses, and entering into contracts and conducting and supporting investigations into the
cause, treatment, or prevention of a disease or disorder as described in paragraphs (1) and
(2).4

The 2009 Influenza Pandemic: Selected Legal Issues

The then-Acting HHS Secretary issued a nationwide public health emergency declaration in
response to human infections from the influenza A(H1N1) virus on April 26, 2009.5 Making such
a determination enables the Secretary to take three types of actions that can be especially useful
for dealing with an emerging influenza outbreak. First, such a determination authorizes the
Secretary to draw from a special emergency fund.6 Second, it is one of three events that can lead
to the issuance of Emergency Use Authorizations under the Federal Food, Drug, and Cosmetic
Act to allow for the use of unapproved medical treatments and tests, under specified conditions, if
needed during an incident.7 Third, if there is a concurrent declaration pursuant to the Stafford Act8
or the National Emergencies Act,9 the Secretary is authorized to waive or modify a number of
administrative requirements, principally involving reimbursement through the Medicare and
Medicaid programs, in order to facilitate the provision of health care items and services by
providers in any geographic area subject to the concurrent declarations.10 Generally, these waivers
and modifications can assist patients who must be relocated due to the inaccessibility of health
care facilities in the emergency area, allow beneficiaries to receive services despite having lost
their documentation of eligibility, and allow providers to provide services in alternate temporary
facilities. Specifically, the Secretary may take some or all of the following actions:
• Waive conditions of participation, certification requirements, program
participation, and pre-approval requirements under Medicare, Medicaid, or the
Children’s Health Insurance Program;11
• Permit health care providers to provide care under Medicare, Medicaid, or the
Children’s Health Insurance Program, even if they are not licensed by the state
with jurisdiction over the emergency area;12
• Waive sanctions under the Emergency Medical Treatment and Active Labor Act
(EMTALA) for certain transfers or redirections of patients away from hospital
emergency rooms;13

5 This determination, which would have expired after 90 days, was renewed by HHS Secretary Kathleen Sebelius on
July 24 at http://www.hhs.gov/secretary/phe_swh1n1.html.
6 The Public Health Emergency Fund does not currently have any monies available. For more information, see CRS
Report RL33579, The Public Health and Medical Response to Disasters: Federal Authority and Funding, by Sarah A.
Lister.
7 See infra at “Emergency Use Authorizations (for Unapproved Countermeasures).”
8 42 U.S.C. § 5121 et seq.
9 50 U.S.C. § 1601 et seq. The National Emergencies Act (NEA) authorizes the President to declare a national
emergency and activate existing statutory provisions that authorize the exercise of special or extraordinary power. The
NEA does not provide any specific emergency authority on its own, but relies upon emergency authority provided in
other statutes. For example, a national emergency declaration under the NEA could authorize the Secretary of HHS to
deploy officers in the Commissioned Corps of the Public Health Service to agencies outside of HHS in response to an
urgent or emergency public health care need. Emergency statutory provisions are not activated automatically, but must
be specifically identified in the President’s declaration before they may be given effect. For more information on the
National Emergencies Act, and declarations made under it, see CRS Report 98-505, National Emergency Powers, by L.
Elaine Halchin.
10 42 U.S.C. § 1320b-5(b).
11 42 U.S.C. § 1320b-5(b)(1).
12 42 U.S.C. § 1320b-5(b)(2). Providers must have equivalent licensing in another state and must not be affirmatively
excluded from practicing in the emergency area.
13 42 U.S.C. § 1320b-5(b)(3). In the event of a pandemic infectious disease, patients can be relocated pursuant to a
state’s pandemic preparedness plan, if one exists. 42 U.S.C. § 1320b-5(b)(3)(B)(ii). For more information on
EMTALA’s requirements, see CRS Report RS22738, EMTALA: Access to Emergency Medical Care, by Edward C.

The 2009 Influenza Pandemic: Selected Legal Issues

• Waive sanctions for violations of the Stark law, which prohibits certain self-
referrals by physicians;14
• Extend deadlines and other timetables for required activities;15
• Waive limitations on payments under Medicare Advantage for care and services
provided by out-of-network providers;16 or
• Waive sanctions and penalties for violations of the HIPAA Privacy Rule such as
the use of protected health information for hospital directories, the disclosure of
protected health information to patients’ families and friends, the distribution of
health care providers’ and insurers’ privacy policies to patients, and individuals’
rights to request restrictions, privacy restrictions, or confidential
communications.17
These waivers and modifications may be retroactively applied by the Secretary to the beginning
of the period during which the concurrent declarations were in effect, and will generally remain in
effect until either of the underlying emergency declarations ends or sixty days have elapsed since
the date on which notice of the waivers or modifications was published.18
With respect to the 2009 influenza pandemic, and pursuant to the declaration of a public health
emergency, the Public Health Emergency Fund is available (but is currently unfunded)19 and
certain Emergency Use Authorizations have been granted by FDA.20 However, the Secretary’s
waiver and modification authority has not been activated because there is no concurrent
presidential declaration under either the Stafford Act or the National Emergencies Act.
Stafford Act Declarations
A presidential declaration under the Stafford Act triggers federal emergency authorities that are
independent of the Secretary’s public health emergency authorities. Declarations under the
Stafford Act fall into two categories: emergency declarations and major disaster declarations. As
of this point in time, there have been no Stafford Act declarations pertaining to the 2009 influenza
pandemic.21 A presidential emergency declaration under the Stafford Act authorizes the President

to direct federal agencies to support state and local emergency assistance activities; coordinate
disaster relief provided by federal and non-federal organizations; provide technical and advisory
assistance to state and local governments; provide emergency assistance through federal agencies;
remove debris through grants to state and local governments; provide assistance to individuals
and households for temporary housing and uninsured personal needs; and assist state and local
governments in the distribution of medicine, food, and consumables.22 The total amount of
assistance available is limited in an emergency declaration to $5 million, “unless the President
determines that there is a continuing need; Congress must be notified if the $5 million ceiling is
breached.”23
Emergency declarations under the Stafford Act in the event of an outbreak of infectious disease
are not unprecedented. In 2000, the detection of West Nile virus in New York and New Jersey
was used as the basis of an emergency declaration under the Stafford Act.24 However, there may
be uncertainty regarding whether a flu pandemic, or any outbreak of infectious disease, would be
eligible for major disaster assistance under the Stafford Act.25
A major disaster declaration authorizes the President to offer all the assistance authorized under
an emergency declaration, and further authorizes funds for the repair and restoration of federal
facilities, unemployment assistance, emergency grants to assist low-income migrant and seasonal
farm workers, food coupons and distribution, relocation assistance, crisis counseling assistance
and training, community disaster loans, emergency communications, and emergency public
transportation.26 Additionally, the total amount of assistance provided in a major disaster
declaration is not subject to a ceiling in the same way as under an emergency declaration.
The authority of the President to declare a major disaster under the Stafford Act in response to a
flu pandemic may be subject to some debate and likely depends upon whether a flu pandemic
would qualify as a “natural catastrophe” under the Stafford Act. FEMA has historically excluded
biological incidents from major disaster declarations under the Stafford Act, but executive policy
under the Bush administration appeared to consider biological incidents, or at least flu pandemics,
to be eligible for major disaster assistance.27

The 2009 Influenza Pandemic: Selected Legal Issues

Although there are differences between the types and amounts of assistance that are authorized by
an emergency or major disaster declaration, either declaration would activate the Secretary’s
waiver or modification authority,28 if concurrent with a public health emergency declaration.
Emergency Use Authorizations (for Unapproved Countermeasures)
Under Section 564 of the Federal Food, Drug, and Cosmetic Act (FFDCA), the Secretary may
declare that an emergency exists which justifies the expedited use of certain medical
countermeasures (1) on the basis of a determination by the Secretary of Homeland Security that
there is a domestic emergency, or a significant potential for a domestic emergency; (2) on the
basis of a determination by the Secretary of Defense that there is a military emergency, or a
significant potential for a military emergency; or (3) on the basis of a “determination by the
Secretary [of HHS] of a public health emergency under Section 247d of Title 42 that affects, or
has a significant potential to affect, national security, and that involves a specified biological,
chemical, radiological, or nuclear agent or agents, or a specified disease or condition that may be
attributable to such agent or agents.” Although a declaration under Section 564 of the FFDCA
may be based on the declaration of a public health emergency under Section 319 of the PHSA,
the two are distinct. An FFDCA emergency declaration lasts up to a year, but can be renewed.29
Upon a declaration under Section 564, the FDA commissioner may authorize the emergency use
of a drug, device, or biological product during the effective period of the declaration.30 An EUA
may apply to a product that is not currently approved for commercial use by the Food and Drug
Administration (FDA).31 Alternatively, the subject of an EUA may already be an FDA-approved
product, but the emergency use justifying the EUA may be one that is not presently approved by
the FDA.32 For example, a drug may be approved for use in the adult population but not for use in
children, in which case an EUA may sanction its use by children. A drug may also be approved
only for a specific disease, in which case an EUA may permit the drug’s use for treating different
conditions.
The issuance of an EUA must also be supported by a number of findings.33 First, the FDA
commissioner must conclude that the underlying agent for which the emergency declaration was
made can cause a serious or life-threatening disease or condition. Second, the commissioner must
conclude, based on available scientific evidence, that (1) it is reasonable to believe that the
product may be effective in diagnosing, treating, or preventing the disease or condition or that the
product may be effective in diagnosing, treating, or preventing a serious or life-threatening

29 21 U.S.C. § 360bbb-3(b)(2). The HHS Secretary must publish “each declaration, determination, advance notice of
termination, and renewal” in the Federal Register. 21 U.S.C. § 360bbb-3(b)(4).

disease or condition caused by a product authorized for emergency use34 and (2) it is reasonable
to believe that the known and potential benefits of the product outweigh its known and potential
risks. Third, the commissioner must conclude that there is no adequate, approved, and available
alternative to the product for diagnosing, preventing, or treating such disease or condition.
Finally, the commissioner must conclude that any other criteria for EUAs, which are prescribed in
regulation, are met.
On April 27, 2009, the FDA issued four Emergency Use Authorizations in response to requests
from the CDC to make available certain drugs, diagnostic tests, and respiratory protection devices
for the response to the H1N1 influenza outbreak.35 Emergency use of a second unapproved
diagnostic test was authorized later that year.36
International Health Regulations (IHR)37
Overview of the IHR
In May 2005, the World Health Assembly adopted a revision of its 1969 International Health
Regulations, giving a new mandate to the World Health Organization (WHO) and member states
to increase their respective roles and responsibilities for the protection of international public
health.38 The IHR(1969) had focused on just three diseases (cholera, plague, and yellow fever). In
addition, compliance of State Parties39 with the IHR(1969) was uneven, a result of, among other
things, resource limitations in poorer countries, and political factors, such as the reluctance to
announce the presence of a contagious disease within one’s borders and face economic and other
consequences.40
The IHR(2005), which entered into force in June 2007, have broadened the scope of the 1969
regulations by addressing existing, new, and re-emergent diseases, as well as emergencies caused
by non-infectious disease agents.41 The IHR(2005) also include provisions regarding designated
national points of contact, definitions of core public health capacities, disease control measures
such as quarantine and border controls, and others. The IHR(2005) require WHO to recommend,
and State Parties to use, control measures that are no more restrictive than necessary to achieve
the desired level of health protection.

34 For example, Vaccinia Immune Globulin (VIG) may be used to treat complications that result from smallpox
vaccinations. See CDC, Smallpox Vaccination – Vaccine Immune Globulin, available at http://www.bt.cdc.gov/training/

The 2009 Influenza Pandemic: Selected Legal Issues

The IHR were agreed upon by a consensus process among the member states, and represent a
balance between sovereign rights and a commitment to work together to prevent the international
spread of disease. The IHR(2005) are binding on all WHO member states as of June 15, 2007,
except for those that have rejected the regulations or submitted reservations.42 While the
IHR(2005) contain mechanisms such as negotiation and arbitration to assist States Parties in
reaching mutually acceptable solutions where disputes arise, ultimately IHR(2005) do not provide
an enforcement mechanism to compel compliance with WHO provisions.43 The United States
accepted the IHR(2005) with three reservations, including the reservation that it will implement
the IHR(2005) in line with U.S. principles of federalism.44 Within five years of the entry into
force date, State Parties must complete development of public health infrastructure that ensures
full compliance with the regulations.
Declaration of a “Public Health Emergency of International Concern”
On April 25, 2009, WHO Director-General Dr. Margaret Chan, upon the advice of the Emergency
Committee, declared that the influenza A(H1N1) virus outbreak constituted a “Public Health
Emergency of International Concern” under the IHR(2005).45 This influenza outbreak marked the
first time under the IHR(2005) that the Director-General convened the Emergency Committee
and determined that a “Public Health Emergency of International Concern” existed. Article 12(1)
of the IHR(2005) authorizes the WHO Director-General to make such a declaration, and Article 1
of the IHR(2005) defines a “Public Health Emergency of International Concern” as “an
extraordinary event which is determined… (i) to constitute a public health risk to other States
through the international spread of disease and (ii) to potentially require a coordinated
international response.”
WHO Recommendations
Under the IHR(2005), if the WHO Director-General declares a “Public Health Emergency of
International Concern,” then the Director-General must issue temporary recommendations which
will depend upon the nature of the threat (Article 15(1)). The IHR(2005) do not preclude State
Parties from implementing measures that achieve a greater level of health protection than WHO
temporary recommendations, provided that such measures are (1) otherwise consistent with the
IHR(2005), and (2) not more restrictive of international trade and travel, and not more invasive or
intrusive to persons, than reasonably available alternatives that would achieve the appropriate
level of health protection (Article 43(1)). Following the declaration of a “Public Health
Emergency of International Concern” on April 25, 2009, the Director-General recommended that
“all countries should intensify surveillance for unusual outbreaks of influenza-like illness and
severe pneumonia.”46 The Director-General, however, did not recommend any travel or trade

The 2009 Influenza Pandemic: Selected Legal Issues

On June 11, 2009, the WHO Director-General announced that the scientific criteria for an
influenza pandemic had been met with regard to the influenza A(H1N1) virus, so that the WHO
pandemic alert level was raised from 5 to 6.47 Again, no travel, border closures, or trade
restrictions were recommended.
International Response to WHO Recommendations
The WHO advised that travel restrictions would have “very little effect on stopping the virus from
spreading, but would be highly disruptive to the travel community.”48 Despite this
recommendation, some countries, such as China and several South American countries,
implemented outright travel bans to or from Mexico. Other countries interrupted sales of pork
products from the United States, disregarding a WHO determination, confirmed by scientists, that
cooked pork does not transmit the virus.49
According to the IHR(2005), State Parties may apply measures that affect travel, even if not
recommended by the Director-General.50 However, such measures must be no more restrictive of
travel, or more intrusive to persons, than reasonably available alternatives that would achieve the
appropriate level of health protection. Thus, State Parties are not supposed to bar the entry of a
conveyance for public health reasons, but are rather are to manage a public health threat through
isolation, quarantine, disinfection, or other such applicable methods.51 If a State Party implements
additional health measures significantly interfering with international traffic, the public health
rationale and relevant scientific information for the measures must be provided to WHO. The
WHO will then share the information with State Parties and institute procedures to find a
mutually acceptable solution.52 Ultimately, however, the IHR(2005) do not provide an
enforcement mechanism to compel compliance with WHO recommendations.53

compliance within the global community, especially in economic terms, to be a powerful compliance tool. The
IHR(2005) (Article 56) contain a dispute settlement mechanism to resolve conflicts which may arise among State
Parties when applying or interpreting the regulations, including options such as negotiation, mediation, conciliation, or
arbitration, or referral to the Director-General of WHO, if agreed to by all the parties to the dispute.

The 2009 Influenza Pandemic: Selected Legal Issues

Quarantine and Isolation Authority54
Federal Authorities
Although the terms are often used interchangeably, quarantine and isolation are two distinct
concepts. Quarantine typically refers to the “(s)eparation of individuals who have been exposed to
an infection but are not yet ill from others who have not been exposed to the transmissible
infection.”55 Isolation refers to the “(s)eparation of infected individuals from those who are not
infected.”56 Primary quarantine authority typically resides with state health departments and
health officials; however, the federal government has jurisdiction over interstate and border
quarantine.
Federal quarantine and isolation authority may be found in Section 361 of the Public Health
Service Act, 42 U.S.C. § 264, wherein Congress has given the Secretary of HHS the authority to
make and enforce regulations necessary “to prevent the introduction, transmission, or spread of
communicable diseases from foreign countries into the States or possessions, or from one State or
possession into any other State or possession.”57 While also providing the Secretary with broad
authority to apprehend, detain, or conditionally release a person, the law limits the Secretary’s
authority to the communicable diseases published in an Executive Order of the President.58
Executive Order 13295 lists the communicable diseases for which this quarantine authority may
be exercised, and specifically includes influenza viruses which have the potential to cause a
pandemic.59 In 2000, the Secretary of HHS transferred certain authorities, including interstate
quarantine authority, to the Director of the CDC.60 Both interstate and foreign quarantine
measures are now carried out by CDC’s Division of Global Migration and Quarantine.61
HHS also works closely with the Department of Homeland Security (DHS) and its agencies. HHS
and DHS signed a memorandum of understanding in 2005 that sets forth specific cooperation
mechanisms to implement their respective statutory responsibilities for quarantine and other
public health measures.62 DHS has three agencies that may aid CDC in its enforcement of
quarantine rules and regulations pursuant to 42 U.S.C. § 268(b). They are U.S. Customs and

Border Protection, U.S. Immigration and Customs Enforcement, and the United States Coast
Guard. In addition to DHS, CDC may also rely on other federal law enforcement agencies and
state and local law enforcement agencies.
Federal and State Coordination
While the federal government has authority to authorize quarantine and isolation under certain
circumstances, it should be noted that the primary authority for quarantine and isolation exists at
the state level as an exercise of the state’s police power. States conduct these activities in
accordance with their particular laws and policies.63 CDC acknowledges this deference to state
authority as follows:
In general, CDC defers to the state and local health authorities in their primary use of their
own separate quarantine powers. Based upon long experience and collaborative working
relationships with our state and local partners, CDC continues to anticipate the need to use
this federal authority to quarantine an exposed person only in rare situations, such as events
at ports of entry or in similar time-sensitive settings.64
Section 311 of the PHS Act65 provides for federal-state cooperative activities to enforce
quarantines. The federal government may help states and localities enforce their quarantines and
other health regulations and, in turn, may accept state and local assistance in enforcing federal
quarantines. The federal government may also assist with or take over the management of an
intrastate incident if requested by a state or if the federal government determines local efforts are
inadequate.66 Under the authority of 42 U.S.C. § 97, the Secretary of HHS may request the aid of
U.S. Customs and Border Protection, Coast Guard, and military officers in the execution of
quarantines imposed by states on vessels coming into ports.

63 A new development in the law relating to quarantine is the possible use of self-imposed or home quarantines. States
may need to consider whether their ability to impose quarantine also includes the authorities necessary to support a
population asked to voluntarily stay at home for a period of time. Federal and state authorities generally provide for the
care of persons mandatorily quarantined, but voluntary home-quarantine situations may pose new issues. See Steven D.
Gravely, et al., Emergency Preparedness and Response: Legal Issues in a Changing World, 17 THE HEALTH LAWYER 1
(June 2005).
64 Q&A on Executive Order 13295, available at http://www.cdc.gov/ncidod/dq/
qa_influenza_amendment_to_eo_13295.htm. The complexities of this shared power have been noted. One analysis
observed that “When it comes to the exercise of isolation and quarantine powers, reality tends to be messier than the
conceptual realm. Public health officials need clear lines of authority in emergency situations, often the moments when
isolation and quarantine might be required. Unfortunately, confusion about which level of government should take the
lead often occurs, thus revealing the ability of quarantine powers to spotlight difficulties federalism poses for public
health.” David P. Fidler, Lawrence O. Gostin, and Howard Markel, “Through the Quarantine Looking Glass: Drug-
Resistant Tuberculosis and Public Health Governance, Law and Ethics,” 35 J. OF LAW, MEDICINE & ETHICS 616 (2007).
Another commentator has noted that “Given the variation in due process rights in connection with quarantine, which
may be afforded under federal and state law, one can foresee the possibility of considerable conflict.” Felice Batlan,

The 2009 Influenza Pandemic: Selected Legal Issues

Proposed Federal Regulations
The CDC, on November 22, 2005, announced proposed changes to its quarantine regulations at
42 C.F.R. Parts 70 and 71.67 These proposed regulations have not been finalized, but Congress
recently mandated that they be promulgated by June 10, 2009.68 These changes will constitute the
first significant revision of the regulations in Parts 70 and 71 in 25 years. The proposed changes
are an outgrowth of the CDC’s experience during the spread of Severe Acute Respiratory
Syndrome (SARS) in 2003, when the agency experienced difficulties locating and contacting
airline passengers who might have been exposed to SARS during their travels. In announcing the
proposed regulations, then CDC Director Julie Gerberding said, “[t]hese updated regulations are
necessary to expedite and improve CDC operations by facilitating contact tracing and prompting
immediate medical follow up of potentially infected passengers and their contacts.”69
The proposed regulations would expand reporting requirements for ill passengers70 on board
flights and ships arriving from foreign countries. They would also require airlines and ocean
liners to maintain passenger and crew lists with detailed contact information and to submit these
lists electronically to CDC upon request.71 The lists would be used to notify passengers of their
suspected exposure if a sick person were not identified until after the travelers had dispersed from
an arriving carrier. The proposed regulations address the due process rights of passengers who
might be subjected to quarantine after suspected exposure to disease; the regulations also provide
for an appeal process.72
Border Entry Issues 73
Inadmissibility of Infected Aliens
Those most easily excluded from the United States are aliens already infected with the influenza
A(H1N1) virus. The Immigration and Nationality Act (INA) specifically bars aliens who are
determined to have “a communicable disease of public health significance,” from receiving visas
and admission into the United States.74 “A communicable disease of public health significance” is

67 See 70 Fed. Reg. 71892 (November 30, 2005), http://www.cdc.gov/ncidod/dq/nprm/. These proposed regulations
were available for a 60-day comment period, which was extended for an additional 30 days, closing on March 1, 2006.
See 71 Fed. Reg. 4544 (January 27, 2006), proposed Section 70.20 and 71.23 of 42 C.F.R.
68 Section 121(c) of P.L. 110-392 states: “Not later than 240 days after the date of enactment of this Act, the Secretary
of Health and Human Services shall promulgate regulations to update the current interstate and foreign quarantine
regulations found in parts 70 and 71 of Title 42, Code of Federal Regulations.”
69 “CDC Proposes Modernizing Control of Communicable Disease Regulation, USA,” Medical News Today,
November 23, 2005, at http://www.medicalnewstoday.com/medicalnews.php?newsid=34042. Since the SARS
outbreak, the CDC has increased its quarantine stations nationwide from 8 to 20. See http://www.cdc.gov/ncidod/dq/
index.htm.
70 The definition of ill person would be expanded to include anyone who has a fever of at least 100.4 degrees plus one
of the following: severe bleeding, jaundice, or severe, persistent cough accompanied by bloody sputum, or respiratory
distress. (Section 70.1 of proposed regulations).
71 Id. The lists, in electronic format, would have to be kept for 60 days after arrival, and be able to be submitted within
12 hours of a CDC request. The lists would include names, contact information and seat assignments.

defined by the Secretary of Health and Human Services by regulation.75 Although the regulatory
definition does not specifically include influenza A(H1N1), it does include, by reference,
communicable diseases as listed in a Presidential Executive Order issued pursuant to section
361(b) of the Public Health Service Act.76 The relevant order, Executive Order 13295, as
amended by Executive Order 13375, specifies “[i]nfluenza caused by novel or reemergent
influenza viruses that are causing, or have the potential to cause, a pandemic” as a communicable
disease for purposes of section 361(b).77 Thus, for purposes of the INA, the influenza A(H1N1)
virus is a ground for inadmissibility into the United States. Of course, this law only applies to
aliens, not citizens, and prior to inadmissibility being triggered, the alien must be diagnosed with
the influenza A(H1N1) virus.78 These considerations could therefore prevent this provision from
being the most effective means to interdict individuals infected with the influenza A(H1N1) virus
from entering the country.
Border Quarantines of Citizens or Aliens
There are currently no legal provisions that can exclude American citizens from the United States
solely because of an infection with a communicable disease. The primary means to prevent
infected citizens from introducing these diseases into the United States is to place them into
quarantine or isolation at the border rather than deny them entry outright. As noted above, the
Secretary has the authority to promulgate regulations to prevent the entry and spread of
communicable diseases from foreign countries into the United States. The implementing
regulations at 42 C.F.R. Part 71 specify that when there is reason to believe an arriving person is
infected with “any communicable disease listed in an Executive Order, as provided under section
361(b) of the Public Service Act,” the person may be isolated, quarantined, or placed under
surveillance or disinfected if deemed necessary to prevent the introduction of the communicable
disease.79 “Influenza caused by novel or reemergent influenza viruses that are causing, or have the
potential to cause, a pandemic” is one such disease that can warrant quarantine.80
Closing the Border
The most drastic measure discussed so far is “to close the borders.” Presumably, this would entail
a blanket bar on all aliens and citizens seeking entry into the United States regardless of their
health. There appear to be no laws specifically authorizing an executive agency to take such
action. However, Congress could presumably enact a law to do so, at least with regard to aliens,
because the Supreme Court has long recognized “the power to expel or exclude aliens as a

fundamental sovereign attribute that is largely immune from judicial control.81 However, United
States citizens cannot be barred from entering the United States.82 Thus, if Congress were to
theoretically “close the borders,” it could do so only by excluding aliens.
In the absence of an act of Congress, it may be possible for the President to “close the borders” to
aliens by Executive Order. However, this course of action appears to be fraught with legal and
practical challenges, which would likely result in extensive litigation. Because Congress has not
given the President authority to conduct blanket closings of borders, it would appear that the
President could do so only if the exclusion power is one where he has concurrent authority with
Congress.83 Although this exclusion power is characterized as a power “exercised by the
Government’s political departments largely immune from judicial control,”84 the President
appears to have rarely exercised any authority within this realm outside of the authority expressly
delegated by an act of Congress. Considering the rather extensive inadmissibility regime codified
within the Immigration and Nationality Act, it would appear unlikely that the President can
exercise this power without express congressional authorization.
Airlines and Travel Restrictions85
Airline Corporate Policies
Generally, airlines are under no legal obligation to provide transportation simply because a person
has a valid ticket. As a matter of corporate policy, airlines have inserted clauses into their
“contract of carriage” reserving the right to deny transportation to any ticketed passenger who
presents himself or herself in a condition that may adversely effect the safety and/or security of
the flight, its crew, or the other passengers. For example, Midwest Airlines’ “contract of carriage”
specifically authorizes the refusal of transportation or removal from a flight if the passenger’s:
age, mental or physical condition, disability or impairment is such that the passenger would
need excessive or unusual assistance in the event of an emergency or to take care of his/her
physical needs in flight, ...86
Thus, it is conceivable that a person presenting himself or herself for air travel with symptoms of
illness could be denied the right to board.87 Application and interpretation of this provision

87 Airlines also have general authority to refuse to board passengers with communicable diseases under certain
circumstances pursuant to Air Carrier Access Act of 1986 (ACAA) regulations. See 49 U.S.C. § 41705, 14 C.F.R. §
382.51. Decisions to deny passengers scheduled to fly must be based on “reasonable judgment that relies on current
medical knowledge or on the best available objective evidence,” that the individual poses a direct threat to the health
and safety of others. See, discussion, infra at “Federal Nondiscrimination Laws”, regarding the application of federal
nondiscrimination laws, including the nondiscrimination provisions of the ACAA.

appears to be at the sole discretion of the air carrier. Should an individual be refused
transportation, he or she may, depending on the terms of the “contract of carriage,” be eligible for
a refund for any unused portion of the ticket purchased minus any taxes or applicable service
fees.
CDC has issued interim guidance to assist airline crew in identifying passengers who may be
infected with influenza A(H1N1).88 This guidance provides that any passengers with certain
symptoms should be reported immediately to the CDC quarantine station in the airport where the
plane is expected to land.
Public Health “Do Not Board” List
Federal agencies have developed a new travel restriction tool to prevent the spread of
communicable diseases of public health significance.89 The public health Do Not Board (DNB)
list was developed by the Department of Homeland Security (DHS) and the CDC, and made
operational in June 2007.90 The DNB list enables domestic and international health officials to
request that persons with communicable diseases who meet specific criteria and pose a serious
threat to the public be restricted from boarding commercial aircraft departing from or arriving in
the United States. The list provides a new tool for management of emerging public health threats
when local public health efforts are not sufficient to keep people with certain contagious diseases
from boarding commercial flights.91
Federal Airspace Authority
In addition to the legal authority over individual passengers, the federal government possesses the
legal authority to regulate and control the navigable airspace of the United States. The notion that
every nation has absolute and exclusive sovereignty over the airspace above its defined territory
is a hallmark aviation principle that has been recognized by international agreements dating back
to the 1919 Convention for the Regulation of Aerial Navigation.92 The United States Congress
has, by statute, delegated the legal authority over airspace regulation to the Administrator of the
Federal Aviation Administration (FAA).93 Pursuant to this authority, it appears that the FAA can
prevent airplanes from entering the airspace of the United States if they originate from a county
experiencing incidents of communicable disease (e.g., airplane from Mexico to any airport in the
United States). Similarly, the FAA could deny airspace access to any airplane originating in the
United States whose intention it is to operate into a country experiencing incidents of
communicable disease (e.g., an airplane from any domestic airport to Mexico). Finally, the FAA
can prevent aircraft originating in third countries from utilizing the airspace of the United States

to travel to a country experiencing incidents of communicable disease (e.g., airplane originating
in Canada destined for Mexico).
School Closures94
Since children tend to be more susceptible than adults to infection and are responsible for more
secondary transmission,95 studies have suggested that community-wide school closures may help
mitigate the impact of an influenza pandemic.96 The Centers for Disease Control and Prevention
(CDC), in interim pre-pandemic planning guidance, included school closures as a tool for
mitigation of a pandemic and, in some cases, the period of closure could be as long as 12 weeks.97
During the spring 2009 H1N1influenza outbreak over 700 schools closed for varying lengths of
time.98 However, additional information on the virus led to less use of school closures. CDC
issued revised guidance on May 5, 2009, and noted that new information, indicating the disease
severity was similar to that of seasonal influenza, warranted revision of the original
recommendation.99
On August 7, 2009, new guidelines for elementary and secondary schools were issued to help
decrease the spread of flu among students and school staff.100 This guidance emphasizes that
“[t]he decision to dismiss students should be made locally and should balance the goal of

reducing the number of people who become seriously ill or die from influenza with the goal of
minimizing social disruption and safety risks to children sometimes associated with school
dismissal.”101 The recommended school responses are staying home when sick for at least twenty-
four hours after a fever, separating ill students and staff, using hand hygiene, routinely cleaning
commonly touched surfaces, treating high-risk students and staff early, and considering selective
school dismissals.102 If the flu appears to be causing more severe disease, other additional
measures may be recommended, including active screening for fevers, advising high-risk students
and staff to stay home, advising students with ill household members to stay home, and school
dismissals.103 CDC and the Department of Education (ED) have established a school dismissal
monitoring system in order to track school dismissals.104 In addition, ED has provided
recommendations to help schools maintain the continuity of learning both for individuals or small
groups of students and for large groups of students disrupted by school dismissals or large
numbers of faculty absences.105
School closures may spawn numerous policy issues including when and how long schools should
be closed; how schools can comply with standardized testing requirements; and whether school
meals programs should continue.106 However, school closures also raise legal issues. The main
question is who has the legal authority to institute a school closure. A CDC-requested study of
state legal authorities to close schools found that school closure is legally possible in most
jurisdictions during both routine and emergency situations.107 The study also indicated that state
authority for closure may be vested at various levels of government and in different departments,
generally the state or local education agencies or state or local departments of health.108 However,
if there is a state or local declaration of emergency, the authority to close schools shifts to the
state emergency management agencies in most jurisdictions.109 These varying laws may create

education regarding responses to H1N1. Like the guidance for elementary and secondary schools, the higher education
guidance contains two main sets of recommendations: (1) recommendations which assume that H1N1 has a severity
similar to the spring/summer outbreak, and (2) recommendations to consider if the disease becomes more severe. These

legal controversies over who has the authority to make the school closure decision. In addition,
there could be legal challenges to whatever school closure decision is made, particularly if the
duration of a school closing is lengthy. Issues may also arise regarding whether school employees
will be paid for the time the schools are closed.110
Vaccinations
Background111
Vaccination with a matched strain of influenza virus is considered the most effective measure to
prevent severe illness from flu.112 Since influenza viruses continuously change, creating a
matched strain is not possible until a virus is circulating. The production of a vaccine is time
consuming, and, assuming that the decision is made to conduct a mass vaccination campaign,113
the vaccine will become available in phases, not all at one time. When the vaccine is first
produced, it is likely that the demand for the H1N1 vaccine will be greater than the supply.114
CDC states that vaccination planners should assume shipping of vaccine will begin mid-October,
although some vaccine may be available for shipping starting late September.115
Vaccines may be mandated in some circumstances; however, except for the Department of
Defense and with respect to immigration, it is generally a matter of state, rather than federal,
authority.116 The current federal plans for a possible pandemic flu vaccination campaign in the fall
assume that any such a campaign will be voluntary.117

The 2009 Influenza Pandemic: Selected Legal Issues

Allocation of Vaccines118
Overview
If a decision is made to conduct a voluntary mass vaccination campaign, the federal government
would purchase the vaccine and a blended public- and private-sector distribution approach would
be used.119 The federal government would provide guidance to the states and localities on how the
vaccine should be allocated but actual allocation decisions would be made at the state and local
levels. CDC has stated, however, that “State and local health departments are strongly encouraged
to adhere to national guidelines on vaccine prioritization. Uniformity in prioritizing vaccine is
considered a significant national interest. There may be instances where specific local needs
should be taken into consideration when implementing prioritization, but deviation from national
guidelines should be minimized.”120
Selected Federal Actions Prior to 2009
The federal government examined the issue of how to set priorities for scarce resources, including
vaccines, prior to the current H1N1 pandemic.121 The 2005 Homeland Security Council
Implementation Plan,122 as supplemented by the two-year summary implementation plan,
required HHS with the Department of Homeland Security (DHS) to make priority
recommendations for access to pre-pandemic and pandemic influenza vaccines.123 The
recommendations were to reflect the pandemic response goals as well as maintaining national
security.124 On December 14, 2006, HHS issued a request for information (RFI) in the Federal
Register
asking for “input on pandemic influenza vaccine prioritization considerations from all
interested and affected parties.... ”125 In addition, the RFI indicated that limiting transmission may
be an objective. The federal interagency working group used the input gained from this RFI to
issue draft guidance on October 17, 2007.126
After consideration of comments, HHS and the Department of Homeland Security issued final
guidance on July 23, 2008 in the form of a report entitled “Guidance on Allocating and Targeting
Pandemic Influenza Vaccine.”127 The guidance creates tiers for coverage, and varies the

vaccination priority depending on the severity of the pandemic. Since pandemics that have higher
case fatality rates are more likely to disrupt essential services, threaten public order and homeland
security, and disrupt supply chains, individuals who are necessary for these functions would
receive a higher priority in a severe pandemic. Conversely, individuals with high risk conditions
making them more vulnerable to serious illness would receive greater priority in a less severe
pandemic.128 The guidance gives its highest rank to deployed forces, critical health care workers,
fire and police, and pregnant women, infants, and toddlers. The importance of maintaining
homeland and national security is highlighted and the guidance recognizes the following
objectives as the most important:
• protecting those who are essential to the pandemic response and providing care
for persons who are ill,
• protecting those who maintain essential community services,
• protecting children, and
• protecting workers who are at greater risk of infection due to their job.129
However, the guidance also recognizes that the plans must be flexible because “the guidance may
be modified based on the status of vaccine technology, the characteristics of pandemic illness, and
risk groups for severe disease—factors that will remain unknown until a pandemic actually
occurs.”130
Federal Actions After Emergence of Influenza A(H1N1)
On July 8, 2009, CDC issued recommendations for state and local planning for a pandemic flu
vaccination program.131 These recommendations again emphasized that changing data may
change the target populations. CDC recommended the following groups be targeted first for
vaccines:
• students and staff associated with schools and children at or over six months and
staff in child care centers (vaccinated at schools and child care centers);
• pregnant women, children six months to four years old, new parents and
household contacts of children (vaccinated at providers’ offices and community
clinics);
• adults under 65 years old with medical conditions that increase the risk of
complications from flu (vaccinated at work settings, community clinics,
pharmacies, providers’ offices); and
• health care workers and emergency services sectors personnel (vaccinated at
work settings, providers’ offices).132

The 2009 Influenza Pandemic: Selected Legal Issues

The CDC recommendations noted that immunization of military forces may be appropriate given
the current circumstances but did not address the military in its allocation discussion. The CDC
focused only on the vaccination of civilian populations under the authority of CDC and state and
local health departments.133
On July 29, 2009, the CDC’s Advisory Committee on Immunization Practices (ACIP) met to
make recommendations on H1N1 vaccine priorities. The ACIP recommendations generally track
those issued on July 8 by CDC for planning purposes. However, instead of students and staff
associated with schools and children at or over six months and staff in child care centers, the
ACIP recommends vaccination of people who live with or care for children younger than 6
months, and people between 6 months and 24 years old in order to cover college students. The
groups recommended for priority vaccination by the ACIP total approximately 159 million people
in the United States.134 If there is a shortage of vaccine, the ACIP recommends that the following
groups receive the vaccine first:
• pregnant women,
• people who live with or care for children younger than 6 months of age,
• health care and emergency services personnel with direct patient contact,
• children 6 months through 4 years old, and
• children 5 through 18 years old who have chronic medical conditions.135
During the press briefing, the ACIP noted that it recommends that 83% of the population be
vaccinated for seasonal influenza, but less than 40% are actually vaccinated each year. The
demand for the H1N1 vaccine is uncertain because not everyone who is in a priority group may
choose to get the vaccine. Hence, with more vaccine potentially available to lower tiers in the
priority groupings, ACIP noted in the press briefing that it may be possible that the more limited
target groups might not be used.136 Similarly, CDC stated that a vaccine shortage is not expected;
however, availability and demand are unpredictable, thus it is possible that priority groups may be
needed.137 CDC also observed that the ACIP recommendations “leave room for flexibility at the
local level depending on the local vaccine supply situation.”138
Legal Issues
The allocation of scarce pandemic vaccine could raise several legal issues. If an individual has an
adverse response to the vaccine, there may be liability issues. However, HHS Secretary Kathleen
Sebelius issued a declaration under the Public Readiness and Emergency Preparedness Act (PREP
Act)139 which waives vaccine liability, except for willful misconduct, for the United States, and
for manufacturers; distributors; program planners; persons who prescribe, administer, or dispense

the countermeasure; and employees of any of the above. This declaration would also make funds
available under a vaccine compensation fund.140
Constitutional due process and equal protection issues as well as civil rights issues might also be
raised concerning vaccine allocation if a particular covered group was adversely impacted by the
vaccine allocation plan.141 More specifically, issues regarding the Americans with Disabilities Act
(ADA) 142 could be raised. However, vaccine allocation plans that are based on a determination
that an individual not receive a vaccine because the vaccine would not be effective given his or
her health situation would be unlikely to raise ADA concerns, because the determination would
be based on a medical determination of treatment. Similarly, the mere fact that a decision would
have a disparate impact on individuals with disabilities would not necessarily be sufficient to
violate the nondiscrimination mandates.143
Other potential legal issues could arise concerning state and local decisions about vaccine
allocation. Questions may occur about defining subgroups within priority groups. For example,
how is a “health care worker” to be defined? Once the groups are defined, issues may arise
concerning how vaccination sites will ensure that individuals are within the priority group. For
example, would an individual have to “prove” that he or she had a medical condition that
increased risk from the flu?144 What form would this proof have to take? Would there be potential
liability issues for health care providers if they do not follow guidance concerning who is to be
vaccinated? Would vaccinations be provided for illegal aliens who are within the priority groups?
Finally, if there is possible liability for individuals or state or local agencies making these
decisions, should there be any legal protections available to limit liability?
Mandatory Vaccinations145
History and Precedent
Historically, the preservation of the public health has been the primary responsibility of state and
local governments, and the authority to enact laws relevant to the protection of the public health
derives from the state’s general police powers.146 With respect to the preservation of the public
health in cases of communicable disease outbreaks, these powers may include the enactment of
mandatory vaccination laws.147 Every state has a law requiring children to be vaccinated before

they enroll in a public or private school.148 All states also allow medical exemptions from school
vaccination requirements for those whose immune systems are compromised, who are allergic to
vaccines, or have other medical contraindications to vaccines, and many states also provide
exemptions for religious or philosophical reasons.149 Various state laws also require vaccination
against hepatitis B and meningococcal disease for incoming college and university students.150
Jacobson v. Massachusetts151 is the seminal case regarding a state’s or municipality’s authority to
institute a mandatory vaccination program as an exercise of its police powers. In Jacobson, the
Supreme Court upheld a Massachusetts law that gave municipal boards of health the authority to
require the vaccination of persons over the age of 21 against smallpox, and determined that the
vaccination program instituted in the City of Cambridge had “a real and substantial relation to the
protection of the public health and safety.”152 In upholding the law, the Court noted that “the
police power of a State must be held to embrace, at least, such reasonable regulations established
directly by legislative enactment as will protect the public health and the public safety.”153 The
Court added that such laws were within the full discretion of the state, and that federal powers
with respect to such laws extended only to ensure that the state laws did not “contravene the
Constitution of the United States or infringe any right granted or secured by that instrument.”154
In the context of the current H1N1 pandemic, mandatory vaccination issues are less likely to arise
than allocation issues, since it is unlikely that there would be sufficient vaccine available to
vaccinate the entire population, particularly in the early stages of vaccine availability.155
Health Care Workers and Mandatory Vaccinations
A number of states have laws requiring employees of certain health care facilities, such as nursing
homes, to be vaccinated against diseases such as measles, mumps and rubella. Such laws, which
vary widely, generally contain opt-out provisions where a vaccine is medically contraindicated or
if the vaccine is against the individual’s religious or philosophical beliefs.156 A few states have
laws pertaining to influenza vaccination of health care workers, and most that do provide for

voluntary influenza immunization programs and staff education measures for employees;
however, a few states have mandatory requirements for influenza vaccinations for health care
workers.157 For example, Alabama has a law requiring that employees of nursing homes receive
an annual vaccination against the influenza virus, unless the vaccine is medically contraindicated,
or the vaccine is against the individual’s religious beliefs, or if the individual refuses the vaccine
after being fully informed of the health risks of not being immunized.158 Recently, the New York
State Health Department amended its regulations to require that health care workers at hospitals,
in home health care agencies, and in hospice care be immunized against influenza viruses as a
precondition to employment and on an annual basis.159 This regulation was enacted as an
emergency measure and could apply to the influenza A(H1N1) virus if a vaccine becomes
available in sufficient supply.
In the private sector, employers can require health care workers to be vaccinated against
communicable diseases as a condition of employment, unless a state law applies which permits
employees to opt out.160 Virginia Mason Medical Center in Seattle, Washington, became the first
hospital in the nation, in 2004, to make vaccination a condition of employment for all its
employees. Within three years, the hospital reported 98% staff coverage, except for 2% of the
staff who refused for medical or religious reasons, and, because of their refusal, were required to
wear surgical masks when in the hospital.161
In 2008, the Department of Defense (DOD) issued a policy directive requiring “all civilian health
care personnel who provide direct patient care in DoD military treatment facilities to be
immunized against seasonal influenza infection each year as a condition of employment, unless
there is a documented medical or religious reason not to be immunized.”162
Vaccination Orders During a Public Health Emergency
Many states also have laws providing for mandatory vaccinations during a public health
emergency or outbreak of a communicable disease. Generally, the power to order such actions
rests with the governor of the state or with a state health officer. For example, a governor may
have the power to supplement the state’s existing compulsory vaccination programs and institute
additional programs in the event of a civil defense emergency period.163 Or, a state health officer

may, upon declaration of a public health emergency, order an individual to be vaccinated “for
communicable diseases that have significant morbidity or mortality and present a severe danger
to public health.”164 In addition, exemptions are generally provided for medical reasons or where
objections are based on religion or conscience.165 However, if a person refuses to be vaccinated,
he or she may be quarantined during the public health emergency giving rise to the vaccination
order. The legality of a particular mandatory vaccination program will hinge upon balancing the
severity of the public health emergency with the effectiveness and safety of the vaccine involved,
and the availability of less intrusive methods of dealing with the situation. For example, dealing
with the introduction of smallpox by a terrorist might involve the use of national security powers
and involve some consequential restrictions on individual civil liberties. However, most programs
for protecting the public health also recognize and protect constitutional rights to personal
liberties, such as freedom from physical restraint, bodily invasion, or the right to refuse medical
treatment.166
Model State Emergency Health Powers Act
In addition to the current laws, many states have considered and have passed some or all of the
provisions set forth in the Model State Emergency Health Powers Act (Model Act).167 The Model
Act was drafted by The Center for Law and the Public’s Health at Georgetown and Johns
Hopkins Universities.168 It seeks to “grant public health powers to state and local public health
authorities to ensure strong, effective, and timely planning, prevention, and response mechanisms
to public health emergencies (including bioterrorism) while also respecting individual rights.”
With respect to vaccinations, the Model Act includes provisions similar to the current laws
discussed above. Under the Model Act, during a public health emergency, the appropriate public
health authority would be authorized to “vaccinate persons as protection against infectious
disease and to prevent the spread of contagious or possibly contagious disease.” The Model Act
requires that the vaccine be administered by a qualified person authorized by the public health
authority, and that the vaccine “not be such as is reasonably likely to lead to serious harm to the
affected individual.” The Model Act recognizes that individuals may be unable or unwilling to
undergo vaccination “for reasons of health, religion, or conscience,” and provides that such

individuals may be subject to quarantine to prevent the spread of a contagious or possibly
contagious disease.169
Role of the Federal Government
Federal jurisdiction over public health matters derives from the Commerce Clause, which states
that Congress shall have the power “[t]o regulate Commerce with foreign Nations, and among the
several States.... ”170 Thus, under the Public Health Service Act, the Secretary of Health and
Human Services has authority to make and enforce regulations necessary “to prevent the
introduction, transmission, or spread of communicable diseases from foreign countries into the
States or possessions, or from one State or possession into any other State or possession.”171 With
regard to foreign countries, the Secretary has the power to restrict the entry of groups of aliens for
public health reasons.172 This power includes the authority to issue vaccination requirements for
immigrants seeking entry into the United States.173 With regard to interstate commerce, the Public
Health Service Act deals primarily with the use of quarantine measures to halt the spread of
certain communicable diseases.174 The Public Health Service Act does not specifically authorize
any mandatory vaccination programs; nor do there appear to be any regulations regarding the
implementation of a mandatory vaccination program at the federal level during a public health
emergency.
As noted above, state and local governments have the primary responsibility for protecting the
public health, and this has been reflected in the enactment of the various state laws authorizing
mandatory vaccination procedures during a public health emergency. Any federal civilian
mandatory vaccination program applicable to the general public would likely be limited to areas
of existing federal jurisdiction, i.e., interstate and foreign commerce, similar to the federal
quarantine authority.175 Aliens seeking admission to the United States, for example, are already
required to show proof of required vaccinations.176 This limitation on federal jurisdiction
acknowledges that states have the primary responsibility for protecting the public health, but that
under certain circumstances, federal intervention may be necessary.

The 2009 Influenza Pandemic: Selected Legal Issues

Civil Rights177
Introduction
Infectious diseases, such as the 2009 influenza pandemic, may raise a classic civil rights issue: to
what extent can an individual’s liberty be curtailed to advance the common good? The United
States Constitution and federal civil rights laws provide for individual due process and equal
protection rights as well as a right to privacy, but these rights are balanced against the needs of
the community. With the advance of medical treatments in recent years, especially the use of
antibiotics, the civil rights of the individual with a contagious disease have been emphasized.
However, classic public health measures such as quarantine, isolation, and contact tracing are,
nevertheless, available in appropriate situations and, as new or resurgent diseases have become
less treatable, some of these classic public health measures have been increasingly used.
Therefore, the issue of how to balance these various interests in a modern culture that is sensitive
to issues of individual rights has become critical.178
Constitutional Rights to Due Process and Equal Protection
Constitutional rights to due process and equal protection may be implicated by the imposition of a
quarantine or isolation order.179 The Fifth and Fourteenth Amendments prohibit governments at
all levels from depriving individuals of any constitutionally protected liberty interest without due
process of law. What process may be due under certain circumstances is generally determined by

177 This section was written by Nancy Lee Jones, Legislative Attorney.
178 For a detailed discussion of constitutional issues relating to quarantine see Michelle A. Daubert, “Pandemic Fears
and Contemporary Quarantine: Protecting Liberty Through a Continuum of Due Process Rights,” 54 BUFFALO L. REV.
1299 (January 2007). For an analysis of how to balance the sometimes competing interests of personal and economic
liberties with the public’s health and security see Lawrence O. Gostin, “When Terrorism Threatens Health: How Far
are Limitations on Personal and Economic Liberties Justified?” 55 Fla. Law Rev. 1105 (December 2003). See also
David P. Fidler, Lawrence O. Gostin, and Howard Markel, “Through the Quarantine Looking Glass: Drug-Resistant
Tuberculosis and Public Health Governance, Law and Ethics,” 35 J. OF LAW, MEDICINE & ETHICS 616 (2007), where
the authors note that courts have set four limits on isolation and quarantine authority: the subject must actually be
infectious or have been exposed to infectious disease, the subject must be placed in a safe and habitable environment,
the authority must be exercised in a non-discriminatory manner, and there must be procedural due process.
179 It has been argued that the federal quarantine authority may not pass constitutional muster since it does not
specifically provide for a right to a fair hearing. See Howard Markel, Lawrence O. Gostin, and David P. Fidler,
“Extensively Drug-Resistant Tuberculosis: An Isolation Order, Public Health Powers, and a Global Crisis,” 298 JAMA
83-84 (July 4, 2007). It should be noted that the proposed CDC quarantine regulations contain detailed due process
procedures including a right to a hearing for full quarantine. 70 Fed. Reg. 71,892 (November 30, 2005),
http://www.cdc.gov/ncidod/dq/nprm/. However, these proposed regulations have been strongly criticized for what
commentators have described as constitutional failings. These criticisms have highlighted the lack of independent
judicial review for individuals subject to quarantine, the broad discretion accorded to directors of federal quarantine
stations, the lack of hearings during provisional quarantine, and privacy concerns. See, e.g., Lawrence O. Gostin,

balancing the individual’s interest at stake against the governmental interest served by the
restraints, determining whether the measures are reasonably calculated to achieve the
government’s aims,180 and deciding whether the least restrictive means have been employed to
further that interest.
In O’Connor v. Donaldson,181 the Supreme Court examined the civil commitment of an individual
to a mental hospital and held that “a State cannot constitutionally confine without more, a
nondangerous individual who is capable of surviving safely in freedom by himself or with the
help of willing and responsible family members or friends.”182 Arguably, an individual who is
highly contagious with a serious illness may be considered dangerous, and thus subject to
involuntary confinement if there is no less restrictive alternative. The lesson of Donaldson is that
such confinements must be carefully examined in order to comport with the constitutional right to
due process. Donaldson also raises the issue of whether less restrictive programs are required
prior to the imposition of the more restrictive application of isolation or quarantine. It could be
argued that the least restrictive alternative must first be applied or more restrictive alternatives
will run afoul of constitutional requirements.183
The unequal treatment of certain socially disfavored groups with regard to quarantine also raises
equal protection issues. For example, in Wong Wai v. Williamson184 a board of health resolution
mandated Chinese residents to be quarantined for bubonic plague unless they submitted to
inoculation with a serum with “the only justification offered for this discrimination ... a
suggestion ... that this particular race is more liable to the plague than any other.”185 The court
struck the resolution as a violation of the equal protection clause.186
Although the Constitution does not specifically grant a right to travel, the Supreme Court has held
that there is a fundamental right to travel.187 This right, and the applicable due process procedures,

180 See, e.g., Jacobson v. Massachusetts, 197 U.S. 11, 27 (1905) (enforcement of public health laws must have some
“real or substantial relation to the protection of the public health and the public safety”); Jew Ho v. Williamson, 103 F.
10 (C.C.N.D. Cal. 1900) (quarantine of San Francisco district inhabited primarily by Chinese immigrants purportedly
to control the spread of bubonic plague was invalidated).

183 See Wendy D. Parmet, “Legal Power and Legal Rights—Isolation and Quarantine in the Case of Drug-Resistant
Tuberculosis,” 357 NEW ENG. J. OF MEDICINE 433, 435 (August 2, 2007). Professor Parmet argues that compulsory
measures are not the most effective and may prompt individuals who may be subject to them to evade authorities. “By
ensuring that coercion is used only when less restrictive alternatives will not work and with due regard for the rights of
those detained, the law can foster public trust, minimizing the need for compulsion and laying the groundwork for the
comprehensive and costly control programs needed to prevent the spread of XDR tuberculosis and other contagious
pathogens.” Id.
184 103 F. 1 (N.D. Cal. 1900).
185 Id. at 15.
186 One commentator observed that it is unlikely that such blatantly discriminatory actions would occur today, but noted
that “studies of New York City’s use of isolation orders for tuberculosis in the 1990s show that more than 90% of the
people detained were non-white and more than 60% were homeless.... Although these figures may reflect the
democracy (sic) of non-compliant patients with tuberculosis in New York City at that time, the fact that the most potent
public health tool was used primarily against marginalized, nonwhite persons underscores the need for legal
oversight—if only so that affected communities can be assured of the absence of discrimination.” Wendy D. Parmet,

have been examined in the context of transportation security, particularly regarding alleged
terrorists.188 Generally, restrictions on travel, such as identification policies for boarding
airplanes, have not been found to violate the Constitution.189 If the public safety arguments have
prevailed regarding restrictions due to transportation security, they would be likely to prevail
against a serious public health threat. However, the seriousness of the threat and the due process
procedures used would be key to any constitutional determination.
Federal Nondiscrimination Laws
In addition to constitutional issues, discrimination against an individual with an infectious disease
may be covered by certain federal laws, notably Section 504 of the Rehabilitation Act,190 the
Americans with Disabilities Act (ADA),191 and the Air Carrier Access Act (ACAA).192 However,
under these statutes, an individual with a contagious disease does not have to be given access to a
place of public accommodation or employment if such access would place other individuals at a
significant risk.193
Section 504 of the Rehabilitation Act
Although the language of Section 504 does not specifically discuss contagious diseases, the
Supreme Court dealt with discrimination issues in the context of tuberculosis and Section 504 in
School Board of Nassau County v. Arline.194 The Court found that in most cases an individualized
inquiry is necessary in order to protect individuals with disabilities from “deprivation based on
prejudice, stereotypes, or unfounded fear, while giving appropriate weight to such legitimate
concerns of grantees as avoiding exposing others to significant health and safety risks.”195 The
Court adopted the test enunciated by the American Medical Association amicus brief and held
that the factors which must be considered include “findings of facts, based on reasonable medical
judgments given the state of medical knowledge, about (a) the nature of the risk (how the disease
is transmitted), (b) the duration of the risk (how long is the carrier infectious), (c) the severity of

the risk (what is the potential harm to third parties) and (d) the probabilities the disease will be
transmitted and will cause varying degrees of harm.” The Court also emphasized that courts
“normally should defer to the reasonable medical judgments of public health officials.”196
The Americans With Disabilities Act
The ADA provides nondiscrimination protections to individuals with contagious diseases, but
balances this protection with requirements designed to protect the health of other individuals.
Title I of the ADA, which prohibits employment discrimination against otherwise qualified
individuals with disabilities, specifically states that “the term ‘qualifications standards’ may
include a requirement that an individual shall not pose a direct threat to the health or safety of
other individuals in the workplace.”197 In addition, the Secretary of Health and Human Services is
required to publish, and update, a list of infectious and communicable diseases that may be
transmitted through handling the food supply.198
Similarly, Title III, which prohibits discrimination in public accommodations and services
operated by private entities, states the following:
Nothing in this title shall require an entity to permit an individual to participate in or benefit
from the goods, services, facilities, privileges, advantages and accommodations of such
entity where such individual poses a direct threat to the health or safety of others. The term
‘direct threat’ means a significant risk to the health or safety of others that cannot be
eliminated by a modification of policies, practices, or procedures or by the provision of
auxiliary aids or services.199
Although Title II, which prohibits discrimination by state and local government services, does not
contain such specific language, it does require an individual to be “qualified” which is defined in
part as meeting “the essential eligibility requirements of the receipt of services or the participation
in programs or activities.”200 This language has been found by the Department of Justice to
require the same interpretation of direct threat as in Title III.201
Contagious diseases were discussed in the ADA’s legislative history. The Senate Report noted that
the qualification standards permitted with regard to employment under Title I may include a
requirement that an individual with a currently contagious disease or infection shall not pose a
direct threat to the health or safety of other individuals in the workplace and cited to School
Board of Nassau County v. Arline
,202 the Section 504 case discussed previously.203 Similarly, the

The Air Carrier Access Act205
The Air Carrier Access Act (ACAA) prohibits discrimination by air carriers against “otherwise
qualified individual[s]” on the basis of disability.206 Enacted in 1986,207 prior to the ADA, the
ACAA contains no statutory reference to communicable diseases, but the regulatory text
specifically addresses them. 208 Additionally, the regulatory definition of “individual with a
disability” appears to include individuals with communicable diseases.209 The regulations prohibit
various actions by carriers against individuals with communicable diseases. A carrier may not
“(1) [r]efuse to provide transportation to the passenger; (2) [d]elay the passenger’s transportation
... ; (3) [i]mpose on the passenger any condition, restriction, or requirement not imposed on other
passengers; or (4) [r]equire the passenger to provide a medical certificate.”210 However, an
exception applies when “the passenger’s condition poses a direct threat.”211 The regulations
define “direct threat” as “a significant risk to the health or safety of others that cannot be
eliminated by a modification of policies, practices, or procedures, or by the provision of auxiliary
aids or services.”212

Liability Issues
The Public Readiness and Emergency Preparedness Act (PREP
Act)213

The “Public Readiness and Emergency Preparedness Act” (PREP Act)214 created § 319F-3 of the
Public Health Service Act, which can limit claims based on public health “countermeasures,”
such as drugs or vaccines, when used under specified emergency conditions. Specifically, upon a
determination by the Secretary of HHS that either a public health emergency or the credible risk
of such emergency exists,215 the Secretary may declare that, with one exception, certain “covered
persons” shall be immune from suit under state and federal law with respect to claims arising
from the administration or use of a “covered countermeasure.”
“Covered persons” include the United States, manufacturers, distributors, program planners,216
persons who prescribe, administer or dispense the countermeasure, and employees of any of the
above. A “covered countermeasure” includes (A) “a qualified pandemic or epidemic product,” (B)
“a security countermeasure,” or (C) a drug, biological product, or device that is authorized for
emergency use in accordance with section 564 of the Federal, Food, Drug, and Cosmetic Act.217
Each of the terms in (A), (B), and (C) is itself defined in the PREP Act.
The one exception to absolute immunity applies to suits which allege that death or serious
physical injury resulted from the willful misconduct of a covered person. These cases may be
brought exclusively under a new federal cause of action, with special pleading requirements and
procedures specified under the PREP Act. Some potential defendants, such as state or local
officials and health care providers who administer or dispense the countermeasure, may also
avoid liability for a death or physical injury if they act consistently with guidance issued by the
Secretary of HHS and also notify public health authorities of any resulting death or injury within
seven days after the death or injury is discovered.218
As an alternative to litigation, victims may accept payment under the “Covered Countermeasure
Process Fund,” if Congress has appropriated money for that purpose.219 Compensation under this

215 This declaration authority is independent of the Secretary’s authority under Section 319 of the Public Health Service
Act, 42 U.S.C. 247d, and other similar authorities.
216 Program planners include “a State or local government, including an Indian tribe, a person employed by the State or
local government, or other person who supervised or administered a program with respect to the administration,
dispensing, distribution, provision, or use of a security countermeasure or a qualified pandemic or epidemic product,
including a person who has established requirements, provided policy guidance, or supplied technical or scientific
advice or assistance or provides a facility to administer or use a covered countermeasure.” 42 U.S.C. § 247d-6d(i)(6).

fund would be in the same amount as is prescribed by sections 264, 265, and 266 of the Public
Service Health Act for persons injured as a result of the administration of certain countermeasures
against smallpox.220 These three sections provide, respectively, medical benefits, compensation
for lost employment income, and death benefits, but do not provide damages for pain and
suffering.
On June 25, 2009, HHS Secretary Kathleen Sebelius issued a declaration under the PREP Act for
the use of H1N1 pandemic vaccines that are currently under development, thereby providing
immunity and enabling the compensation program, contingent upon appropriations.221 Earlier, on
June 19, the Secretary amended an earlier declaration, providing immunity and enabling
compensation (contingent upon appropriations) for the use of the antiviral drugs Tamiflu and
Relenza for treatment of illnesses caused by H1N1 pandemic flu.222
Civil Liability of Volunteers and Volunteer Health Professionals223
When disasters occur, it is common for volunteer health professionals (VHPs) to go to affected
areas and offer their medical services. Typically, such individuals are licensed medical
professionals who gratuitously provide their services in response to these regions’ clear need for
medical skills and services. In these scenarios, questions have arisen regarding the potential civil
liability of VHPs, particularly with regard to medical malpractice liability. The civil liability of
VHPs may be a concern that arises within the context of the 2009 influenza pandemic depending
upon the development of the pathogen and how future events unfold.
A patchwork of federal and state laws generally operates to protect volunteers, which may include
VHPs, and there are also laws that trigger liability protection specifically for VHPs. Whether a
VHP is protected from civil liability depends on a number of factors, including under whose
control the VHP operates and whether or not a state of emergency has been declared. It is
important to note that liability protections shield volunteers from all civil liability for negligent
conduct, i.e., a failure to take adequate care that results in injuries or losses to others. Civil
liability for conduct that is more egregious than mere negligence, such as willful, or grossly
negligent conduct, is generally not protected.
Volunteer Protection Acts
Laws shielding volunteers from liability have been enacted on both the federal and state level;
these statutes apply in non-emergency situations as well as emergency situations. On the federal

entities for ordinary negligence so long as certain conditions are met.225 The VPA does not
prohibit the non-profit or governmental entity from bringing a civil action against its own
volunteers; nor does the VPA shield from liability the non-profit or governmental entity for the
actions of its volunteers. Furthermore, it expressly preempts state standards that provide less
protection.226 All fifty states and the District of Columbia have enacted their own volunteer
protection statutes that provide liability protection greater than the federal VPA but to varying
degrees. Additionally, many states have enacted statutory provisions geared specifically toward
providing VHPs with immunity from civil liability and that, like the VPA, are not dependent on,
or triggered by, an emergency situation.227
Liability Protection During a State of Emergency
Except insofar as they waive it, the federal and state governments enjoy sovereign immunity from
suit. The federal government has waived its immunity with the passage of the Federal Tort Claims
Act,228 and some state governments have similar statutory provisions. Such acts generally
immunize government employees from tort liability for torts committed within their scope of
employment, and instead allow the government to be held liable in accordance with the law of the
state where a tort occurred.
An additional way to shield VHPs from individual civil liability during an emergency is to
declare them non-paid employees of the federal government or a state government for liability
purposes.229 This can be done for particular volunteers in all situations or only when a general
state of emergency or public health emergency has been declared.230 Emergencies can be declared
at both federal and state levels.231 Every state has a regime for declaring a general emergency or
disaster, and such a declaration can explicitly trigger liability protections or allow the governor to
do so.232 In addition to general emergency procedures, some states have regimes for public health

225 42 U.S.C. § 14503(a).
226 Id. at § 14503(d). However, the VPA permits states to enact statutes that declare the non-applicability of the act “to
any civil action in a State court against a volunteer in which all parties are citizens of the State.” See id. at § 14502.
Thus far, only New Hampshire has done so.
227 In addition to VPAs, every state and the District of Columbia has enacted its own “Good Samaritan” statute, which
protects individuals who gratuitously provide emergency assistance from civil liability.
228 28 U.S.C. §§ 1346(b), 2671-80. See CRS Report 95-717, Federal Tort Claims Act, by Henry Cohen and Vivian S.
Chu.
229 The Pandemic and All-Hazards Preparedness Act, P.L. 109-417, provides an example of such tort liability
protections. Under 42 U.S.C. § 300hh-11(d)(1), the Secretary of the HHS may appoint volunteer health professionals as
intermittent personnel of the National Disaster Medical System (NDMS), which provides medical services when a
disaster overwhelms local emergency services. NDMS volunteers benefit from the same immunity from civil liability
as the employees of the Public Health Service. The Secretary may also accept the assistance of the VHPs as temporary
volunteers under 42 U.S.C. § 217b. Under applicable regulations, such volunteers may receive legal protections
including protection from civil liability claims under the FTCA. See e.g., 45 C.F.R. § 57.5; see http://www.hhs.gov/

emergencies, which, like general emergency management statutes, provide varying degrees of
coverage. The declaration of a public health emergency triggers special protections for medical
personnel, which often include liability protection for VHPs. Even where emergency or public
health emergency statutes do not explicitly grant liability protections to VHPs, these statutes
generally allow governors to impose such protections for volunteers where appropriate.
Emergency Mutual Aid Agreements
Emergency mutual aid agreements may be instituted among political subdivisions and Indian
tribal nations within a state, out-of-state with neighboring political subdivisions, or internationally
with Canadian provinces. Approved by Congress in 1996, the Emergency Management
Assistance Compact (EMAC)233 provides a prearranged structure for a state to request aid from
other states when affected by disaster. Since 1996, all fifty states have agreed to the terms of
EMAC, as have the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam. Under
EMAC, a person from one state who renders assistance in another and who holds a license,
certificate, or other permit for the practice of professional, mechanical, or other skills is
considered to be licensed, certified, or permitted to exercise those duties in the requesting state,
subject to limitations or conditions set by the governor of the requesting state. Notwithstanding
the recognition of out-of-state licenses, reciprocity is not automatically extended to VHPs who do
not provide services pursuant to an EMAC request for assistance. Following September 11, 2001,
Congress created the Emergency System for Advance Registration of Volunteer Health
Professionals so that emergency managers and others can have the ability to quickly identify and
facilitate the use of VHPs in local, state, and federal emergency response.234
Employment Issues
Introduction235
Questions relating to employment are among the most significant issues presented by an
influenza pandemic, since, if individuals fear losing their employment or their wages, compliance
with public health measures such as isolation or quarantine may suffer. Controlling or preventing
an influenza pandemic involves the same strategies used for seasonal influenza. These strategies
are vaccination, treatment with antiviral medications, and the use of infection control measures.236
CDC states that vaccination planners should assume that shipping of H1N1 vaccine will begin
mid-October, although some vaccine may be available for shipping starting late September.237
Therefore, the use of other infection control measures may be critical. The uses of quarantine and
isolation, as well as social distancing and “snow days,” are discussed in the Homeland Security

233 P.L. 104-321. EMAC is intended to encourage mutual assistance in “any emergency or disaster that is duly declared
by the governor of the affected state(s),” including “natural disaster, technological hazard, man-made disaster, civil
emergency aspects of resources shortages, community disorders, or enemy attack.” EMAC, Art. I. See also CRS Report

Council’s Pandemic Influenza Implementation Plan238 as ways to attempt to limit the spread of
influenza.239
Quarantine is defined as the “separation of individuals who have been exposed to an infection but
are not yet ill from others who have not been exposed to the transmissible infection.”240 Isolation
is defined as the “separation of infected individuals from those who are not infected.”241 Social
distancing is defined as “infection control strategies that reduce the duration and/or intimacy of
social contacts and thereby limit the transmission of influenza.”242 Social distancing can include
the use of face masks, teleconferencing, or school closures. “Snow days,” a type of social
distancing, are the recommendation or mandate by authorities that individuals and families limit
social contacts by remaining within their households.243
The Centers for Disease Control and Prevention (CDC) issued interim planning guidance for
communities to mitigate the impact of pandemic influenza.244 This guidance introduced a
Pandemic Severity Index, which ranks the severity of a pandemic like the categories given to
hurricanes and links the severity to specific community interventions. The community
interventions include isolation and voluntary quarantine, school dismissals, and the use of social
distancing measures to reduce contact. The social distancing measures include the cancellation of
large public gatherings and the alteration of workplace environments and schedules to decrease
social density.245 The guidance noted the importance of workplace leave policies that would
“align incentives and facilitate adherence with the nonpharmaceutical interventions.... ”246
Strategies to minimize the impact of workplace absenteeism were discussed in some detail and
included the use of staggered shifts and telework. Unemployment insurance was mentioned as
potentially available, as was disaster unemployment assistance. The guidance also observed that
the Family and Medical Leave Act may offer some job security protections.247
The National Governors Association Center for Best Practices (NGA Center) conducted nine
regional pandemic preparedness workshops during 2007 and 2008 to “examine state pandemic
preparedness, particularly in non-health-related areas such as continuity of government,
maintenance of essential services, and coordination with the private sector.” A report analyzing
the information gained during these workshops identified areas in which new or improved

The 2009 Influenza Pandemic: Selected Legal Issues

policies and procedures are necessary to improve pandemic preparedness. One of these areas was
workforce policies. The NGA Center concluded:
Every sector examined in this report will be affected by the availability of workers during a
pandemic. In general, states and the private sector should develop and test policies affecting
the willingness and ability of personnel to perform their duties, whether in traditional or
alternative settings. Potential strategies and or guidance addressing telecommuting,
alternative schedules, or modified operating hours for retail establishments and Internet or
distance-learning programs for school children would be particularly useful. During a
pandemic, almost everyone will be susceptible to the illness. A central disease control
strategy will be keeping sick people away from others to minimize the spread of infection.
Employers should examine their human resource policies and, if needed, create new policies
that would allow sick workers to stay at home during a pandemic. When possible, states and
private sector employers should collaboratively develop policies that effectively balance the
need of some workers to care for sick (or healthy) family members for extended periods of
time with the requirements government and private sector continuity of operations plans.248
Wrongful Discharge in Violation of Public Policy249
The employment-at-will doctrine governs the employment relationship between an employer and
employee for most workers in the private sector. An employee who does not work pursuant to an
employment contract, including a collective bargaining agreement that may permit termination
only for cause or may identify a procedure for dismissals, may be terminated for any reason at
any time.
Although the employment-at-will doctrine provides the default rule for most employees, it has
been eroded to some degree by the recognition of certain wrongful discharge claims brought
against employers. In general, these wrongful discharge claims assert tort theories against the
employer. A cause of action for wrongful discharge in violation of public policy is one such
claim. If isolation or a quarantine were used to attempt to limit the spread of a pandemic influenza
virus and an employee was terminated because of absence from the workplace, a claim for
wrongful discharge in violation of public policy might arise.
A claim for wrongful discharge in violation of public policy is grounded in the belief that the law
should not allow an employee to be dismissed for engaging in an activity that is beneficial to the
public welfare. In general, the claims encompass four categories of conduct:
• refusing to commit unlawful acts (e.g., refusing to commit perjury when the
government is investigating the employer for wrongdoing);
• exercising a statutory right (e.g., filing a claim for workers’ compensation,
reporting unfair labor practices);
• fulfilling a public obligation (e.g., serving on jury duty); and
• whistleblowing.250

Progress and Opportunity

The 2009 Influenza Pandemic: Selected Legal Issues

Although most states appear to recognize a claim for wrongful discharge in violation of public
policy, it is possible that a state may allow a claim only under certain circumstances. For
example, Texas recognizes such a claim only if an employee is terminated for refusing to perform
an illegal act or inquiring into the legality of an instruction from the employer.251
While the four categories of conduct identified above represent the classic fact patterns for a
claim of wrongful discharge in violation of public policy, other actions could be deemed
beneficial to the public welfare and result in a wrongful discharge claim if an employee is
terminated for engaging in such actions. Some courts have broadly defined what constitutes
“public policy.” For example, in Palmateer v. International Harvester Co., the Illinois Supreme
Court indicated that
[t]here is no precise definition of the term. In general, it can be said that public policy
concerns what is right and just and what affects the citizens of the State collectively. It is to
be found in the State’s constitution and statutes and, when they are silent, in its judicial
decisions.252
Similarly, in Boyle v. Vista Eyewear, Inc., the Missouri Court of Appeals stated that public policy
“is that principle of law which holds that no one can lawfully do that which tends to be injurious
to the public or against the public good.”253 These broad definitions suggest that an employee’s
isolation or quarantine during a pandemic in some states could possibly provide a public policy
exception to the at-will rule of employment. It would seem possible for a court to conclude that
the isolation or quarantine of individuals during a pandemic serves the public good and that the
termination of individuals who are isolated or quarantined violates public policy. Some observers
insist, however, that no court has ever held that it violates public policy to discharge an individual
because he or she missed work because of a quarantine.254
If the government were to mandate individuals to isolate or quarantine themselves either because
they were infected or because of the risk of infection, it would seem that such an action would
constitute an even stronger argument for the public policy exception to the at-will rule of
employment. In such case, the government would appear to be identifying a significant policy
that would benefit the public good. However, even if the government merely recommended
isolation or quarantine rather than mandated such actions, a strong argument for a public policy
exception to the at-will rule would still seem possible. In either case, the government would seem
to be establishing a policy in furtherance of the public’s best interests.

The 2009 Influenza Pandemic: Selected Legal Issues

The Family and Medical Leave Act255
Overview of Family and Medical Leave Rights
The Family and Medical Leave Act256 (“FMLA”) guarantees eligible employees 12 workweeks of
unpaid leave during any 12-month period for one or more of the following reasons:
• because of the birth of a son or daughter of the employee and in order to care for
such son or daughter;
• because of the placement of a son or daughter with the employee for adoption or
foster care;
• in order to care for a spouse or a son, daughter, or parent of the employee, if such
spouse, son, daughter, or parent has a serious health condition; and
• because of a serious health condition that makes the employee unable to perform
the functions of the position of such employee.257
The FMLA defines an “eligible employee” as one who has been employed for at least 12 months
by the employer from whom leave is requested, and who has been employed for at least 1,250
hours of service with such employer during the previous 12-month period.258 The FMLA applies
only to employers engaged in commerce (or in an industry affecting commerce) that have at least
50 employees who are employed for each working day during each of 20 or more calendar
workweeks in the current or preceding calendar year.259
During an influenza pandemic, the FMLA would seem to provide infected employees and
employees who care for certain infected relatives with the opportunity to be absent from the
workplace.260 The FMLA defines a “serious health condition” to mean “an illness, injury,
impairment, or physical or mental condition” that involves either “inpatient care in a hospital,
hospice, or residential medical care facility; or ... continuing treatment by a health care
provider.”261 An employee who was affected by a pandemic influenza virus may be found to have

257 29 U.S.C. § 2612(a)(1).
258 29 U.S.C. § 2611(2). The term “eligible employee” does not include most federal employees. Federal employees are
covered generally under the Federal Employees Family Friendly Leave Act (“FEFFLA”). See 5 U.S.C. § 6307(d)
(permitting the use of sick leave to care for a family member having an illness or injury, and to make arrangements for
or to attend the funeral of a family member). The U.S. Office of Personnel Management has issued a document that
contemplates telework, alternative work arrangements, and excused absences during a pandemic. See U.S. Office of
Personnel Management, Human Capital Planning for Pandemic Influenza (2006) http://www.govexec.com/pdfs/

75-mile radius of an employee’s worksite are subject to the FMLA even if they may have fewer than 50 employees at a
single worksite.)

pandemic).

The 2009 Influenza Pandemic: Selected Legal Issues

a serious health condition. If the FMLA’s eligibility requirements were met, such an employee
would likely be granted leave under the statute.262
In addition, because the FMLA grants leave to an employee to care for a spouse, child, or parent
with a serious health condition, an employee could be granted leave to care for a relative who was
affected by a pandemic influenza virus if the employee met the statute’s eligibility requirements.
While on leave, the employee with the serious health condition or the employee caring for a
spouse, child, or parent with a serious health condition could be isolated or quarantined without
the fear of termination for at least 12 workweeks.263
In contrast, an employee who was not infected by a pandemic influenza virus or who was not
responsible for the care of a spouse, child, or parent infected by such a virus would not be
protected by the FMLA. If such an employee sought isolation or quarantine to avoid exposure and
was absent from the workplace, the FMLA would not prohibit the employer from terminating the
employee.
State and Federal Laws Providing Employment Protections
At least six states, recognizing the lack of statutory protection for employees in a situation where
isolation or quarantine may be necessary, have enacted legislation that explicitly prohibits the
termination of an employee who is subject to isolation or quarantine. In Delaware, Iowa, Kansas,
Maryland, Minnesota, and New Mexico, an employer is prohibited from terminating an employee
who is under an order of isolation or quarantine, or has been directed to enter isolation or
quarantine.264 Under Minnesota law, an employee who has been terminated or otherwise
penalized for being in isolation or quarantine may bring a civil action for reinstatement or for the
recovery of lost wages or benefits.265
Two additional states have enacted legislation that addresses the treatment of employees who are
subject to quarantine or isolation. Under New Jersey law, an affected employee must be reinstated
following the quarantine or isolation.266 Under Maine law, an employer is required to grant leave
to an employee who is subject to quarantine or isolation.267 The leave granted by the employer
may be paid or unpaid.268

262 It is possible that an employee could be affected by a pandemic influenza virus and not develop a serious health
condition. In such case, the employee would not be eligible for leave under the Family and Medical Leave Act.
263 Although the Family and Medical Leave Act allows for at least 12 workweeks of leave, it does not guarantee the
payment of wages during such leave. Under section 102(d)(2)(B) of the act, 29 U.S.C. § 2612(d)(2)(B), an employer
may require the employee to substitute paid vacation or sick leave for the leave granted under the act. If such a
substitution is not made, the employee is likely to be granted unpaid leave.

268 The availability of wage or income replacement because of quarantine or isolation has been addressed by some
commentators. See, e.g., Nan D. Hunter, “Public-Private” Health Law: Multiple Directions in Public Health, 10 J.
Health Care L. & Pol’y 89 (2007). Many commentators maintain that existing wage or income replacement programs,
such as unemployment and workers compensation, would probably not provide compensation for most employees
affected by quarantine or isolation. Replacement wages were, however, reportedly paid during at least one quarantine.

The 2009 Influenza Pandemic: Selected Legal Issues

Although federal law does not protect from termination employees who may be absent from the
workplace because of isolation or quarantine, there are examples of employee protections that are
arguably analogous.269 The FMLA, for example, does grant leave to an eligible employee who has
a serious health condition or who provides care to a spouse, child, or parent with a serious health
condition. Moreover, an expansion of the FMLA to allow for at least eight weeks of paid leave
because of a serious health condition or to care for a spouse, child, or parent with such a condition
has been proposed.270 The availability of paid leave would likely minimize concerns about lost
wages during an influenza pandemic.271
The Uniformed Services Employment and Reemployment Rights Act (USERRA) provides
another example of employee protection.272 USERRA requires the reemployment of an employee
who has been absent from a position of employment because of service in the uniformed services.
USERRA and the FMLA illustrate Congress’s awareness of events that may necessitate an
employee’s absence from the workplace.

wages. See Guenter B. Risse, Revolt Against Quarantine: Community Responses to the 1916 Polio Epidemic, Oyster
Bay, New York
, Transactions & Stud. of the College of Physicians of Philadelphia, Mar. 1992, at 34 (“Garbage cans
were distributed free of charge, and quarantined families received replacement wages to compensate for loss of
income”). Disaster unemployment assistance pursuant to the Stafford Act may also be a possibility if it is determined
that the act is applicable to an influenza pandemic. See CRS Report RL34724, Would an Influenza Pandemic Qualify
as a Major Disaster Under the Stafford Act?
, by Edward C. Liu; CRS Report RS22022, Disaster Unemployment
Assistance (DUA)
, by Julie M. Whittaker and Alison M. Shelton (discussing the availability of disaster unemployment
benefits pursuant to a disaster declaration under the Stafford Act).
269 During the SARS (Severe Acute Respiratory Syndrome) epidemic, Canadian laws and regulations were amended to
provide for special employment insurance coverage for health care workers who were unable to work because of SARS
and to provide for unpaid leave if an individual was unable to work due to a SARS-related event, such as being under
individual medical investigation. See Institute for Bioethics, Health Policy and Law, Quarantine and Isolation: Lessons
Learned from SARS
at 58-59 (November 2003).

available pursuant to federal law, see CRS Report RL34088, Leave Benefits in the United States, by Linda Levine.
271 Some states are exploring the availability of paid leave as part of their state disability insurance programs. In 2002,
legislation that extends disability insurance benefits to individuals who are unable to perform their work because they
are “caring for a seriously ill child, parent, spouse, or domestic partner” was enacted in California. See Cal. Unemp.
Ins. Code §§ 3300-3306. Under the so-called Paid Family Leave Insurance Program, an individual who meets the
program’s requirements is eligible for benefits equal to one-seventh of the individual’s weekly benefit amount on any
day in which he or she is unable to perform the individual’s regular or customary work. Similar legislation has been
enacted in New Jersey. See A. 873, 213th Leg., Reg. Sess. (N.J. 2008).
