Isolation vs Quarantine
People who are ill with a contagious disease are put into isolation to prevent the disease from spreading. Healthy individuals who have been exposed to a dangerous contagious disease are put into quarantine.
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. (For example: the first US Ebola patient Thomas Duncan was in isolation).
Quarantine separates and restricts the movement of people who were exposed to a contagious disease to see if they become sick.
(For example: Duncan’s family members who shared a small Dallas apartment with him, was put in Quarantine)
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
