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. The goal is to monitor these individuals for symptoms and ensure they do not transmit the disease to others. During quarantine, individuals typically stay at home or in designated facilities for a specific period, often 14 days, depending on the disease. This measure helps protect the wider community by reducing the risk of outbreaks and allows health authorities to track and manage potential cases effectively.
