The 2019-2020 coronavirus pandemic is an ongoing pandemic of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The outbreak was first identified in Wuhan, Hubei, China, in December 2019, and was recognized as a pandemic by the World Health Organization (WHO) on 11 March 2020. As of 27 March, more than 536,000 cases of COVID-19 have been reported in over 190 countries and territories, resulting in approximately 24,100 deaths and more than 125,000 recoveries.

The virus is mainly spread during close contact and via respiratory droplets produced when people cough or sneeze. Respiratory droplets may be produced during breathing but the virus is not considered airborne. People may also catch COVID-19 by touching a contaminated surface and then their faces. It is most contagious when people are symptomatic, although spread may be possible before symptoms appear. The time between exposure and symptom onset is typically around five days, but may range from 2 to 14 days.

Common symptoms include fever, cough, and shortness of breath, also a loss of taste and smell has been recognised in a number of cases. Complications may include pneumonia and acute respiratory distress syndrome. There is no known vaccine or specific antiviral treatment. Primary treatment is symptomatic and supportive therapy. Recommended preventive measures include hand washing, as the virus is killed by soap, which bursts its protective bubble. Other recommendations include covering one's mouth when coughing, maintaining distance from other people, and monitoring and self-isolation for people who suspect they are infected.

Efforts to prevent the virus spreading include travel restrictions, quarantines, curfews, workplace hazard controls, event postponements and cancellations, and facility closures. These include the first (arguably successful) quarantine of Hubei, national or regional quarantines elsewhere in the world, curfew measures in China and South Korea, various border closures or incoming passenger restrictions, screening at airports and train stations, and outgoing passenger travel bans.Schools and universities have closed either on a nationwide or local basis in more than 124 countries, affecting more than 1.2 billion students.

The pandemic has led to severe global socioeconomic disruption, the postponement or cancellation of sporting, religious, and cultural events, and widespread fears of supply shortages which have spurred panic buying. Misinformation and conspiracy theories about the virus have spread online, and there have been incidents of xenophobia and racism against Chinese and other East and Southeast Asian people.
