COVID-19 is a virus that usually causes  respiratory symptoms that can feel much like a cold, a flu, or pneumonia. COVID-19 may attack more than your lungs and respiratory system. Other parts of your body may also be affected by the disease.

• Most people with COVID-19 have mild symptoms, but some people become severely ill.
• Some people including those with minor or no symptoms may suffer from post-COVID conditions — or “long COVID”.
