An infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that was first identified in December 2019 in Wuhan, China, and then spread globally, resulting in a pandemic. Common symptoms include fever, cough, fatigue, shortness of breath, loss of appetite, sputum production, and muscle and joint pains, and loss of smell and taste. Severe cases may progress to acute respiratory distress syndrome (ARDS), multi-organ failure, septic shock, and blood clots. Spread of the virus occurs between people during close contact, most often via small droplets produced by coughing, sneezing, and talking. Less commonly, people may become infected by touching a contaminated surface and then touching their face.
