If you had close contact with a person with COVID-19 (an exposure), you need to stay home and away from others (quarantine). COVID-19 can take up to 14 days to make you sick, and some people with COVID-19 never feel sick, so you need to separate yourself from others so you don't spread the virus without knowing it.
