Quarantine is a public health practice used to prevent the spread of infectious diseases. It involves separating and restricting the movement of individuals who may have been exposed to a contagious illness, such as COVID-19 or Ebola. This helps to ensure that if they are infected, they do not transmit the disease to others. During quarantine, individuals typically stay at home or in a designated facility for a specific period, often 14 days. They are monitored for symptoms and may be tested for the disease. Quarantine is an important tool in controlling outbreaks and protecting community health.
