COVID-19 is a disease caused by a type of coronavirus. This illness was first found in December 2019. It has since spread worldwide.
Coronaviruses are a large group of viruses. They cause the common cold. They also cause more serious illnesses like Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). COVID-19 is caused by a novel coronavirus. That means it's a new type that has not been seen in people before.
Follow these guidelines until your doctor tells you it's safe to stop.
If you think you've been exposed, or you're sick, call your doctor as soon as you can. Your doctor may have you take medicine to help prevent serious illness.
A weakened immune system makes it more likely that you'll get very sick from COVID-19. And the COVID vaccine may not work as well for you.
