Answer:
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. Common symptoms include fever, cough, and shortness of breath.Other symptoms may include fatigue, muscle pain, diarrhoea, sore throat, loss of smell, and abdominal pain. The time from exposure to onset of symptoms is typically around five days but may range from two to fourteen days.While the majority of cases result in mild symptoms, some progress to viral pneumonia and multi-organ failure. As of 20 April 2020, more than 2.41 million cases have been reported across 185 countries and territories, resulting in more than 165,000 deaths. More than 632,000 people have recovered.
The virus is primarily spread between people during close contact, often via small droplets produced by coughing, sneezing, or talking.While these droplets are produced when breathing out, they usually fall to the ground or onto surfaces rather than remain in the air over long distances. People may also become infected by touching a contaminated surface and then touching their eyes, nose, or mouth.The virus can survive on surfaces for up to 72 hours. It is most contagious during the first three days after the onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease.
