Quarantine vs. Isolation: What's the Difference?
Edited by Janet White || By Harlon Moss || Updated on October 23, 2023
Quarantine restricts the movement of those exposed to a contagious disease, while isolation separates infected individuals from healthy ones.
Key Differences
Quarantine pertains to the restriction of movement or confinement of individuals who might have been exposed to a contagious disease but aren't necessarily infected. Isolation, on the other hand, involves separating those who are confirmed to be infected from those who are healthy to prevent the spread of the disease.
Quarantine serves as a precautionary measure, targeting individuals who have had potential exposure, even if they display no symptoms. Isolation, conversely, is a reactive measure applied to individuals showing symptoms or having a confirmed diagnosis.
The length of time for quarantine may vary based on the incubation period of the disease and can extend until it's clear the individual isn't infected. In contrast, isolation lasts as long as the individual remains contagious.
Both quarantine and isolation are public health practices aimed at curbing the spread of infectious diseases, but they cater to different groups: potential carriers versus confirmed cases.
