Coronavirus disease 2019 is also known as COVID-19. It is a viral illness that infects the lungs. It is caused by a virus called SARS-associated coronavirus (SARS-CoV-2). This illness was first seen in late 2019 in China and has spread across the world. The signs of COVID-19 are like the flu, and you may have a cough, fever, and it may be hard to breathe. It spreads easily through droplets with the virus when you sneeze or cough. The germs also survive on surfaces like tables, door handles, and telephones. That means you can become sick if you touch a surface with the virus and then touch your face. Some people have a mild case of COVID-19 and are able to stay at home until they feel better. Others may need to be in the hospital if they are very sick. People with COVID-19 most often have to isolate themselves for about 2 weeks. Last Reviewed Date: 2020-03-16
