2019–20 Coronavirus Outbreak

The 2019–20 coronavirus outbreak is an ongoing epidemic of coronavirus disease 2019 (COVID-19), caused by the SARS-CoV-2 virus.[5] It was first identified in December 2019 in Wuhan, China.[6][7][8] As of 28 February 2020, more than 83,000 cases have been confirmed in over 50 countries, of which 8,000 were classified as serious.[4] At least 2,800 deaths have been attributed to the disease,[4] surpassing that of the 2003 SARS outbreak.[9] More than 36,000 people have since recovered.[4]

The virus primarily passes from one person to others via respiratory droplets produced from the airways, often during coughing or sneezing.[10][11] The time between exposure and symptom onset is typically between two and fourteen days.[12] Symptoms may include fever, cough, and breathing difficulties.[13] Complications may include pneumonia and acute respiratory distress syndrome. There is no vaccine or specific antiviral treatment (although research is ongoing); efforts often aim at managing symptoms and supportive therapy.[14] Hand washing, maintaining distance from people who are coughing, and avoiding touching one’s face are recommended to prevent the disease.[15] Anyone who is suspected of carrying the virus is advised to monitor their health for two weeks, self-isolate, wear a surgical mask, and seek medical advice by calling a doctor before visiting a clinic.[12][10] Continue reading “2019–20 Coronavirus Outbreak”
