Quarantine and Isolation

Quarantine officer refers to CFR.

Isolation and quarantine help protect the public by preventing exposure to people who have or may have a contagious disease.

  • Isolation separates sick people with a contagious disease from people who are not sick.
  • Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick.

Twenty U.S. Quarantine Stations, located at ports of entry and land border crossings, use these public health practices as part of a comprehensive Quarantine System that serves to limit the introduction of infectious diseases into the United States and to prevent their spread.
