Quarantine meaning

A strict isolation imposed to prevent the spread of disease.

Quarantine is a public health practice used to prevent the spread of contagious diseases by separating and restricting the movement of people who may have been exposed to an infectious agent but are not yet symptomatic. It is an effective measure for controlling outbreaks of diseases such as COVID-19, tuberculosis, and measles. Quarantine can be implemented at various levels, including individual, group, and community, and can take place in homes, hospitals, or designated facilities. The duration of quarantine depends on the incubation period of the disease and the level of exposure, with the aim of reducing transmission and protecting public health.
