Federal and State Quarantine and Isolation Authority

Summary
In the wake of increasing fears about the spread of highly contagious diseases, federal, state, and
local governments have become increasingly aware of the need for a comprehensive public health
response to such events. An effective response could include the quarantine of persons exposed to
infectious biological agents that are naturally occurring or released during a terrorist attack, the
isolation of infected persons, and the quarantine of certain cities or neighborhoods.
The public health authority of the states derives from the police powers granted by their
constitutions and reserved to them by the Tenth Amendment to the U.S. Constitution. The
authority of the federal government to prescribe quarantine and other health measures is based on
the Commerce Clause, which gives Congress exclusive authority to regulate interstate and foreign
commerce. Thus, state and local governments have the primary authority to control the spread of
dangerous diseases within their jurisdictions, and the federal government has authority to
quarantine and impose other health measures to prevent the spread of diseases from foreign
countries and between states. In addition, the federal government may assist state efforts to
prevent the spread of communicable diseases if requested by a state or if state efforts are
inadequate to halt the spread of disease.
This report provides an overview of federal and state public health laws as they relate to the
quarantine and isolation of individuals and a discussion of constitutional issues that may be raised
should individual liberties be restricted in a quarantine or isolation situation.

Federal and State Quarantine and Isolation Authority

Introduction
In the event of a biological attack or the introduction of a highly contagious disease affecting the
public, the U.S. health system may take measures to prevent those people infected with or
exposed to a disease or a disease-causing biological agent from infecting others. The terms used
to describe these measures, quarantine and isolation, generally apply to distinct groups of persons
but are often used interchangeably. 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.”1 In contrast, isolation refers to the “(s)eparation of infected
individuals from those who are not infected.”2
Varying degrees of quarantine exist, and the authority to order quarantine or isolation is generally
very broad. Primary quarantine authority typically resides with state health departments and
health officials; however, the federal government has jurisdiction over interstate and foreign
quarantine. In addition, the federal government may 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.3
The variety of potential responses—from federal, state, and local authorities—implicates a
number of legal issues. Namely, who is responsible for preventing an outbreak of the disease; and
precisely what may be done? This report will examine federal and state authority to impose
quarantine and isolation measures in order to prevent the spread of infectious disease.4

Federal Authority
Quarantine and Isolation
Federal quarantine and isolation authority derives from the Commerce Clause of the U.S.
Constitution, which states that Congress shall have the power “[t]o regulate Commerce with
foreign Nations, and among the several states.”5 Section 361 of the Public Health Service Act
(PHS Act) grants the Secretary of Health and Human Services (Secretary) the authority to make
and enforce regulations necessary “to prevent the introduction, transmission, or spread of

42 U.S.C. § 264; 42 C.F.R. § 70.2. During the 2003 outbreak of severe acute respiratory syndrome (SARS), U.S.
patients were isolated until they were no longer infectious, allowing them to receive medical care and helping to
contain the spread of the illness. However, there were no individual or population-based quarantines of persons who
may have been in contact with infected persons. The CDC advised persons who were exposed, but not symptomatic, to
monitor themselves for symptoms and further advised home isolation and medical evaluation if symptoms appeared.

communicable diseases from foreign countries into the States or possessions, or from one State or
possession into any other State or possession.”6 The law provides the Secretary with broad
authority to apprehend, detain, or conditionally release a person. However, the Secretary may
only exercise this authority in relation to communicable diseases published in an executive order
issued by the President.7 Executive Order 132958 lists the communicable diseases for which this
quarantine authority may be exercised.9 In 2000, the Secretary transferred certain authorities
related to persons, including quarantine authority, to the Director of the CDC.10 Both interstate
and foreign quarantine measures are now carried out by CDC’s Division of Global Migration and
Quarantine.11
Generally, federal regulations authorizing the apprehension, detention, examination, or
conditional release of individuals are applicable only to individuals coming into a state or
possession from a foreign country or possession.12 To facilitate containment efforts, federal
regulations require airline pilots and ship captains to report immediately the presence of ill
passengers on board their vessels.13
In addition, Section 361 of the PHS Act authorizes the apprehension and examination of
any individual reasonably believed to be infected with a communicable disease in a
qualifying stage14 and
(A) to be moving or about to move from a State to another State; or

42 U.S.C. § 264(a). Violation of federal quarantine and isolation regulations is a criminal misdemeanor, punishable by
fine and/or imprisonment, 42 U.S.C. § 271. The statute also authorizes other public health measures, including
destruction of animals or articles determined to be sources of communicable disease. 42 U.S.C. § 264(a). Originally,
the statute conferred this authority on the Surgeon General; however, pursuant to Reorganization Plan No. 3 of 1966,
all statutory powers and functions of the Surgeon General were transferred to the Secretary of Health, Education, and
Welfare (now Secretary of HHS). In 2000, the Secretary of HHS transferred authority under this provision to the
Director of the Centers for Disease Control and Prevention (CDC). CDC’s Division of Global Migration and
Quarantine carries out quarantine and related activities. http://www.cdc.gov/ncidod/dq/index.htm.

42 C.F.R. § 71.21. During the 2003 response to the severe acute respiratory syndrome (SARS) epidemic, federal
officials provided health alert information to air travelers returning to the United States from areas with SARS
outbreaks, boarded airplanes with travelers reported to be ill to assess their symptoms, and facilitated transport of ill
passengers to hospitals. Federal officials also provided updates to the public and worked with state and local public
health agencies to investigate possible SARS cases. See Mark A. Rothstein et al., Quarantine and Isolation: Lessons
Learned From SARS: A Report to the Centers for Disease Control and Prevention (2003) available at
http://www.instituteforbioethics.com (hereinafter, Quarantine and Isolation).

“Qualifying stage” means that such a disease is (1) in a communicable stage or (2) in a precommunicable state, if the
disease would likely cause a public health emergency if transmitted to other individuals. 42 U.S.C. § 264(d)(2).

(B) to be a probable source of infection to individuals who, while infected with such
disease in a qualifying stage, will be moving from a State to another State.15

If found to be infected, such individuals may be detained for such time and in such manner as
may be reasonably necessary.16 During times of war, the authority to apprehend and examine
individuals extends to any individual “reasonably believed (1) to be infected with such disease [as
specified in an Executive order of the President] and (2) to be a probable source of infection to
members of the armed forces of the United States or to individuals engaged in the production or
transportation of ... supplies for the armed forces.”17
Regulations promulgated pursuant to this authority under the PHS Act may be found in Parts 70
and 71 of Title 42 of the Code of Federal Regulations. Part 70 applies to interstate travel, Part 71
to foreign arrivals.18 The implementing regulations authorize the quarantine and isolation of
individuals in order to prevent the spread of diseases identified in Executive Order 13295.19
In addition, pilots of both interstate flights and flights to the United States are required to report
certain illnesses they encounter during flight in advance of their arrival into the United States to
the CDC Quarantine Station closest to their destination airport.20 There are currently 20 such
stations operated by the CDC located at ports of entry into the United States.21 While there are not
CDC officials at every port of entry, various agencies in the Department of Homeland Security
(DHS) are authorized to assist the CDC in “the enforcement of quarantine rules and
regulations.”22
The Director of the CDC is also authorized to take measures as may be necessary to prevent the
spread of a communicable disease from one state or possession to any other state or possession if
he determines that measures taken by local health authorities are inadequate to prevent the spread
of the disease.23 To prevent the spread of diseases between states, the regulations prohibit infected

In response to the SARS epidemic, the Secretary of HHS in 2003 amended 42 C.F.R. §§ 70.6 and 71.3 to incorporate
by reference Executive Order 13295, thus eliminating rulemaking delays for the publication of new diseases.
19
See 42 C.F.R. § 70.6 (interstate); 42 C.F.R. § 71.32 (foreign). The diseases currently listed are cholera, diphtheria,
infectious tuberculosis, plague, smallpox, yellow fever, viral hemorrhagic fevers (including ebola), severe acute
respiratory syndrome (SARS), and influenza viruses which have the potential to cause a pandemic.

42 C.F.R. §§ 70.4, 71.21(b). It appears as though pilots would report illnesses to the Federal Aviation Administration
(FAA) Air Traffic Services Unit, which would then communicate with the CDC Emergency Operations Center. See

22
42 U.S.C. § 268. 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. Memorandum of
Understanding Between the Department of Health and Human Services and the Department of Homeland Security,
available at http://www.aclu.org/pdfs/privacy/hhs_dhs_mou.pdf. 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 CBP, U.S. Immigration and
Customs Enforcement (ICE), and the U.S. Coast Guard. In addition to DHS, CDC may also rely on other federal law
enforcement agencies and state and local law enforcement agencies.

persons from traveling from one state to another without a permit from the health officer of the
state, possession, or locality of destination, if such a permit is required under the law applicable to
the place of destination.24 Additional requirements apply to persons who are in the
“communicable period of cholera, plague, smallpox, typhus or yellow fever, or who having been
exposed to any such disease, is in the incubation period thereof.”25
The Secretary is also authorized to bar the entry of persons from foreign countries where the
“existence of any communicable disease” poses a “serious danger” of entering the United States
such that “a suspension of the right to introduce such persons and property is required in the
interest of public health.”26 A rule implementing this statutory authority was proposed in 2005,
but was not adopted.27
The PHS Act and related statutes also authorize measures to aid or enforce a quarantine in the
event of a public health emergency. Section 322(a) of the PHS Act28 authorizes the PHS to care
for and treat persons under quarantine. Such persons may also receive care and treatment at the
expense of the PHS from public or private medical facilities when authorized by the officer in
charge of the PHS station at which the application is made.29 Section 311 of the PHS Act30
provides for federal-state cooperative activities to enforce quarantines. The federal government
may assist states and localities in enforcing their quarantines and other health regulations and, in
turn, may accept state and local assistance in enforcing federal quarantines. Under the authority of
42 U.S.C. § 97, the Secretary may request the aid of CBP, the Coast Guard, and military officers
in the execution of quarantines imposed by states on vessels coming into ports.
Criminal sanctions are prescribed for violations of federal regulations issued pursuant to Section
361 of the PHS Act.31 Violation of a federal quarantine or isolation order is a criminal
misdemeanor, and individuals may be subject to a fine of up to $100,000, one year in jail, or both;
organizational violations may be subject to fines of up to $200,000 per event.32 Federal district
courts may enjoin individuals and organizations from violation of CDC quarantine regulations.33

Do Not Board List
In recent years, federal agencies have developed a travel restriction tool to prevent the spread of
communicable diseases of public health significance.34 The public health Do Not Board (DNB)
list was developed by DHS and the CDC, and made operational in June 2007.35 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.36 The list provides a
tool for management of emerging public health threats when local public health efforts are not
sufficient to keep certain contagious individuals from boarding commercial flights.37
In order to place a person on the DNB list, state and local health officials contact their local CDC
quarantine station. The CDC determines if the person is (1) likely contagious with a
communicable disease that presents a serious public health threat, (2) unaware of or likely not to
comply with public health recommendations and medical treatment, and (3) likely to try boarding
a commercial aircraft.38 Once a person is placed on the DNB list,39 airlines are instructed not to
issue a boarding pass to the person for any commercial domestic flight or for a commercial
international flight arriving in or departing from the United States. Other forms of transportation,
such as buses and trains, are not covered by the DNB list. Once a patient is determined to be
noncontagious, the CDC and DHS must remove the person from the list, usually within 24
hours.40
In September 2008, the CDC released a report41 in which it analyzed the first year’s experience
with the DNB list. According to the report, the CDC received 42 requests to add persons to the
DNB list, all of whom had suspected or confirmed pulmonary tuberculosis.42 The agency
approved 33 of the requests, of which 28 were placed by public health departments in the United
States, and 14 were placed on the list while they were outside of the country.43 Two of the 33
persons placed on the DNB list attempted to evade the air travel restriction, and both were

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) and its implementing regulations. See 49 U.S.C. §
41705; 14 C.F.R. §§ 382.19, 382.21.

detained by border officials and taken to local hospitals for evaluation and treatment.44 The CDC
found that “[j]udicious use of the public health DNB list can obviate the human and economic
costs associated with conducting contact investigations when people with communicable diseases
travel on commercial aircraft.”45

State Police Powers and Quarantine Authority
While the federal government has authority to authorize quarantine and isolation under certain
circumstances, the primary authority for quarantine and isolation exists at the state level as an
exercise of the state’s police power. 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.46

Although every state has the authority to pass and enforce quarantine laws as an exercise of its
police powers, these laws vary widely by state. Generally, state and local quarantines are
authorized through public health orders, though some states may require a court order before an
individual is detained.47 For example, in Louisiana, the state health officer is not authorized to
“confine [a person] in any institution unless directed or authorized to do so by the judge of the
parish in which the person is located.”48 Diseases subject to quarantine may be defined by statute,
with some statutes addressing only a single disease, or the state health department may be granted
the authority to decide which diseases are communicable and therefore subject to quarantine.49
States also employ different methods for determining the duration of the quarantine or isolation

Quarantinable Diseases,” May 30, 2014, available at http://www.cdc.gov/quarantine/qa-executive-order-pandemic-listquarantinable-diseases.html. 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.”

fungal, rickettsial, or viral agent, biological toxin, or other biological agent capable of causing extensive loss of life or
serious disability.” MD. CODE ANN., [Public Safety] § 14-3A.

period. Generally, “release is accomplished when a determination is made that the person is no
longer a threat to the public health, or no longer infectious.”50
One common characteristic of many state quarantine laws is their “overall antiquity,” with many
statutes being between 40 and 100 years old.51 The more antiquated laws “often do not reflect
contemporary scientific understandings of disease, [or] current treatments of choice.”52 In the
past, state laws were often enacted with a focus on a particular disease, such as tuberculosis or
typhoid fever, leading to inconsistent approaches in addressing other diseases.53
Until recently, despite the inconsistencies and perceived problems with such laws, state
legislatures have not been forced to reevaluate their quarantine and isolation laws due to a decline
in infectious diseases and advances in public health and medicine.54 However, in light of recent
threats and security concerns, many states have begun to reconsider their emergency response
systems, including the state’s authority to quarantine.55 A review of quarantine authority was
listed as a priority for state governments in the President’s 2002 National Strategy for Homeland
Security.56
Federal authority over interstate and foreign travel is clearly delineated under constitutional and
statutory provisions. Less clear, however, is whether the state police powers may be used to
restrict interstate travel to prevent the spread of disease.57 In a public health emergency, federal,
state, and local authorities may overlap. For example, both federal and state agencies may have
quarantine authority over an aircraft arriving in a large city from a foreign country. Thus,
coordination between the various levels of government would be essential during a widespread
public health emergency.58

Legal Challenges to Quarantine Authority
Public health measures in emergency situations, including quarantine, involve balancing the
rights of individuals with the state’s police power to protect the needs of the public health, safety,

and general welfare. Historically, this balance can be seen in public health crises over the past
century or so. 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. 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.59
Some courts have recognized an individual’s right to challenge his or her quarantine or isolation
by petitioning for a writ of habeas corpus.60 Although the primary function of a writ of habeas
corpus is to test the legality of the detention,61 petitioners often seek a declaration that the statute
under which they were quarantined is unconstitutional.

Dormant Commerce Clause Challenges
In 1824, the Supreme Court in Gibbons v. Ogden alluded to a state’s authority to quarantine under
the police powers.62 In 1902, the Court directly addressed a state’s power to quarantine an entire
geographic area in Compagnie Francaise de Navigation a Vapeur v. Louisiana State Board of
Health,63 where both the law and its implementation were upheld as valid exercises of the state’s
police power. A shipping company in this case challenged an interpretation of a state statute that
conferred upon the state board of health the authority to exclude healthy persons, whether they
came from without or within the state, from a geographic area infested with a disease.64 The
shipping company alleged that the statute as interpreted interfered with interstate commerce, and
thus was an unconstitutional violation of the Commerce Clause. The Court rejected this argument,
holding that although the statute may have had an effect on commerce, it was not
unconstitutional.65 In a subsequent case, the Court made clear that at least where Congress has not

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.

Habeas corpus is “the name given to a variety of writs, having for their object to bring a party before a court or judge.
In common usage, and whenever these words are used alone, they are usually understood to mean the habeas corpus ad
subjiciendum.” Specifically, habeas corpus ad subjiciendum is “a writ directed to the person detaining another, and
commanding him to produce the body of the prisoner, or person detained. This is the most common form of habeas
corpus writ, the purpose of which is to test the legality of the detention or imprisonment; not whether he is guilty or
innocent.” Black’s Law Dictionary, 6th Edition, 1990.

taken action, it is “well settled” that states may impose quarantines to prevent the spread of
disease even though quarantines “affect interstate commerce.”66

Due Process Challenges
In general, courts appear to have declined to interfere with a state’s exercise of police powers
with regard to public health matters “except where the regulations adopted for the protection of
the public health are arbitrary, oppressive and unreasonable.”67 For example, in Miller v.
Campbell City,68 an order to evacuate an area was issued due to leaking methane and hydrogen
gases. After some residents from a subdivision in the area became ill, the county commissioners
declared the subdivision uninhabitable. The plaintiff was arrested when he crossed the roadblock
enforcing the quarantine in an attempt to return home. The Tenth Circuit Court of Appeals upheld
a finding that the evacuation order was substantially related to the public health and safety, and
found no evidence that the quarantine action was taken in bad faith or maliciously.69 The court
noted that the county needed to act quickly because of the potential danger, and did so “with
appropriate concern for the situation and the interests of all involved.”70 The court therefore found
that the plaintiffs were not denied substantive due process. The court also held that because the
plaintiffs were given the opportunity to present their objections orally to the local authorities, and
could have entered written materials as well, the protections of procedural due process were
satisfied.71
Similarly, a federal district court in United States v. Shinnick72 upheld the PHS’s medical isolation
of an arriving passenger because she had been in Stockholm, Sweden, a city declared by the
World Health Organization to be a smallpox-infected area, and she could not show proof of
vaccination.
Likewise, a state court in People ex rel. Barmore v. Robertson73 refused to grant a habeas corpus
petition for a woman who ran a boarding house where a person infected with typhoid fever had
boarded. The woman was not herself infected with the disease, but she was a carrier and had been
quarantined in her home. She argued that her quarantine was unwarranted because she was not
“actually sick,” though the court noted that “[i]t is not necessary that one be actually sick, as that
term is usually applied, in order that the health authorities have the right to restrain his liberties by
quarantine regulations.”74 In justifying quarantine under these circumstances, the court explained

disease”).

that because disease germs are carried by human beings, and as the purpose of an effective
quarantine is to prevent the spread of the disease to those who are not infected, anyone who
carries the germs must be quarantined.75 The court found that in the case of a person infected with
typhoid fever, anyone who had come into contact with that person must be quarantined to prevent
the spread of the disease.76
More recently, a federal district court in New York dismissed a claim alleging violation of
substantive and procedural due process by a plaintiff who was diagnosed with tuberculosis and
confined to a hospital for a few days against his will.77 The court cited to Justice Burger’s
concurrence in O’Connor v. Donaldson, which noted that, pursuant to its police powers, a “[s]tate
may confine individuals solely to protect society from the dangers of significant antisocial acts or
communicable disease.”78 However, at least one state court has ruled that when a state confines
an individual in order to prevent the spread of disease, the state must provide the individual with
procedural due process protections such as, inter alia, notice explaining the grounds for
confinement, the right to counsel, and the right to engage in cross-examination.79
However, some courts have refused to uphold the quarantine of an individual in cases where the
state is unable to meet its burden of proof concerning that individual’s potential danger to others,
or if a restriction is viewed as unreasonable or oppressive.80 In Wong Wai v. Williamson,81 the San
Francisco Board of Health ordered all Chinese residents to be inoculated against bubonic plague
and restricted their right to leave the city, citing nine deaths allegedly from plague. The
inoculations were tainted, causing severe consequences. A court inferred that the regulations were
properly authorized, but nevertheless struck them down as “not based on any established
distinction in the conditions that are supposed to attend the plague, or the persons exposed to its
contagions.”82 Shortly after, in Jew Ho v. Williamson, the same court noted that the quarantine
requirements applied only to Chinese residents and questioned whether bubonic plague actually
caused the reported deaths. It invalidated the quarantine because it was “unreasonable, unjust and
oppressive” and constituted discrimination in violation of the Fourteenth Amendment.83

Additional Potential Challenges

were used to deal with a widespread domestic public health emergency. If government agencies

requisition private facilities for quarantine purposes, such as in the case of overburdened medical
facilities, the legal questions regarding eminent domain power may arise.84
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.85 Such authority may include the ability to offer legal immunity to businesses asked to
provide facilities for quarantine.

Compelled public use of private property in a public health emergency is not unheard of. “In Paris, in August 2003,
after 11,000 deaths were caused by a heat wave, the government took over refrigerated warehouses and similar
facilities to use them as temporary morgues.” Rothstein, Quarantine and Isolation, supra note 13, at 42. Compensation
may be appropriate in some circumstances, but following a volcanic eruption, the State of Washington successfully
argued that continued restricted access to a town near the volcano was a permissible exercise of police power and did
not require compensation. Cougar Business Owners Assn. v. State of Washington, 647 P.2d 481, 486 (Sup. Ct. Wash.
1982). See David G. Tucker and Alfred O. Bragg, III, Florida’s Law of Storms: Emergency Management, Local
Government, and the Police Power, 30 STETSON L. REV. 837 (2001).

Federal and state authorities generally provide for the care of persons mandatorily quarantined (see 42 U.S.C. § 249),
but voluntary home-quarantine situations may pose new issues. See Steven D. Gravely, et al., Emergency Prepared
ness and Response: Legal Issues in a Changing World, 17 THE HEALTH LAWYER 1 (June 2005).
