What is the definition of quarintine?

Quarantine is a restriction on the movement of people and goods which is intended to prevent the spread of disease or pests. It is often used in cases where there is a risk of an infectious disease spreading from one person or group to another. Quarantine can be applied to individuals, groups, or entire communities, and can involve restrictions on travel, contact with others, or both. The length of a quarantine period can vary depending on the disease or pest in question, and may be based on the incubation period of the disease or the time it takes for the pest to reproduce.
