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 China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic.[7][8] Common symptoms include fever, cough, and shortness of breath.[9] Other symptoms may include muscle pain, sputum production, diarrhea, sore throat, loss of smell, and abdominal pain.[4][10][11] While the majority of cases result in mild symptoms, some progress to pneumonia and multi-organ failure.[7][12] As of March 28, 2020, the overall rate of deaths per number of diagnosed cases is 4.6 percent; ranging from 0.2 percent to 15 percent according to age group and other health problems.[13] The virus is mainly spread during close contact and via respiratory droplets produced when people cough or sneeze.[14][15] Respiratory droplets may be produced during breathing but the virus is not generally airborne.[14][16] People may also contract COVID-19 by touching a contaminated surface and then their face.[14][15] It is most contagious when people are symptomatic, although spread may be possible before symptoms appear.[15] The virus can survive on surfaces up to 72 hours.[17] Time from exposure to onset of symptoms is generally between two and fourteen days, with an average of five days.[9][18] The standard method of diagnosis is by reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab.[19] The infection can also be diagnosed from a combination of symptoms, risk factors and a chest CT scan showing features of pneumonia.[20][21] Recommended measures to prevent infection include frequent hand washing, social distancing (maintaining physical distance from others, especially from those with symptoms), covering coughs and sneezes with a tissue or inner elbow, and keeping unwashed hands away from the face.
