COVID-19 stands for "coronavirus disease 2019." It is caused by a virus called SARS-CoV-2. The virus first appeared in late 2019 and quickly spread around the world.

Experts are working on vaccines to prevent COVID-19. Once a vaccine is widely available, if a lot of people get it, the virus will stop spreading so quickly. More information about COVID-19 vaccines is available separately. (See "Patient education: Coronavirus disease 2019 (COVID-19) vaccines (The Basics)".)

Repeated hand washing and use of masks is one of the ways to prevent Covid-19.

Keeping people away from each other is one of the best ways to control the spread of the virus that causes COVID-19. That's because the virus can spread easily through close contact, and it's not always possible to know who is infected. In many areas where the weather is colder and people spend more time inside, cases of COVID-19 have increased.
