coronavirus disease 19

A highly contagious respiratory disease caused by the SARS-CoV-2 virus. SARS-CoV-2 is thought to spread from person to person through droplets released when an infected person coughs, sneezes, or talks. It may also be spread by touching a surface with the virus on it and then touching one’s mouth, nose, or eyes. The most common signs and symptoms of coronavirus disease 19 are fever, cough, and trouble breathing. Muscle pain, chills, headache, sore throat, and a loss of taste or smell may also occur. The signs and symptoms usually appear 2 to 14 days after exposure to the SARS-CoV-2 virus. Some people may not have any symptoms but are still able to spread the virus. Most people with coronavirus disease 19 recover without needing special treatment. But other people are at higher risk of serious illness. Those at higher risk include older adults and people with serious medical problems, such as heart or lung disease, diabetes, cancer, or a weak immune system. Serious illness may include life-threatening pneumonia and organ failure. Research is being done to treat coronavirus disease 19 and to prevent infection with SARS-CoV-2.

Also called COVID-19.
