Specific Laws and Regulations Governing the Control of Communicable Diseases

The Secretary of the Department of Health and Human Services has statutory responsibility for preventing the introduction, transmission, and spread of communicable diseases in the United States. Under its delegated authority, the Division of Global Migration Health works to fulfill this responsibility through a variety of activities, including

the operation of Port Health Stations at ports of entry
establishment of standards for medical examination of persons destined for the United States, and
administration of interstate and foreign quarantine regulations, which govern the international and interstate movement of persons, animals, and cargo.

The legal foundation for these activities is found in Titles 8 and 42 of the U.S. Code and relevant supporting regulations.

Legal Authorities for Isolation and Quarantine

The federal government derives its authority for isolation and quarantine from the Commerce Clause of the U.S. Constitution. Read more on the Legal Authorities for Isolation and Quarantine page.
