Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in 2019 in Wuhan, the capital of Hubei, China, and has since spread globally, resulting in the 2019–20 coronavirus pandemic. Common symptoms include fever, cough, and shortness of breath. Muscle pain, sputum production, diarrhea, and sore throat are less common.
