COVID-19

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a respiratory illness that ranges from mild symptoms to pneumonia or even death. Symptoms occur within 2 to 14 days from exposure to the virus and may include fever, cough, shortness of breath, chills, muscle pain, headache, sore throat, and new loss of sense of taste or smell. COVID-19 may be more severe in people who are older or who have chronic health conditions, such as heart disease or diabetes.
