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 December 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic. The first confirmed case of what was then an unknown coronavirus was traced back to November 2019 in Hubei.
Common symptoms include fever, dry cough, fatigue, sputum production, loss of smell, and shortness of breath. While the majority of cases result in mild symptoms, some progress to viral pneumonia and multi-organ failure. Emergency symptoms include difficulty breathing, persistent chest pain or pressure, confusion, difficulty waking, and bluish face or lips.
The time from exposure to onset of symptoms is typically around five days but may range from two to fourteen days. As of 24 April 2020, more than 2.79 million cases have been reported across 185 countries and territories, resulting in more than 195,000 deaths. More than 781,000 people have recovered.
