If You Are Sick

To keep from spreading respiratory illness to others, you should:

  • Stay home when you are sick.

  • Call your healthcare provider and let them know about your symptoms. Tell them that you have or may have COVID-19. This will help them take care of you and keep other people from getting infected or exposed.
