Coronavirus disease 2019 (COVID‑19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).[9] It was first identified in December 2019 in WuhanHubei, China, and has resulted in an ongoing pandemic. As of 8 September 2020, more than 27.3 million cases have been reported across 188 countries and territories with more than 892,000 deaths; more than 18.3 million people have recovered.[8]

Common symptoms include fever, cough, fatigue, shortness of breath or breathing difficulties, and loss of smell and taste.[6] While most people have mild symptoms, some people develop acute respiratory distress syndrome (ARDS) possibly precipitated by cytokine storm,[10] multi-organ failureseptic shock, and blood clots. The incubation period may range from two to fourteen days.
