COVID 19 (Coronavirus)
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. While the majority of cases result in mild symptoms, some progress to pneumonia and multi-organ failure. The virus is typically spread during close contact and via respiratory droplets produced when people cough or sneeze. Respiratory droplets may be produced during breathing but it is not considered airborne. It may also spread when one touches a contaminated surface and then their face. The virus can live on surfaces for up to 72 hours.
