COVID-19 Information for Specific Groups of People

COVID-19 Information for Specific Groups of People

If you or your family member are at high risk for severe illness, wear a mask or respirator with greater protection in public indoor spaces if you are in an area with a high COVID-19 Community Level. Talk with your healthcare provider about wearing a mask in a medium COVID-19 Community Level.

If you test positive and are an older adult or someone who is at high risk of getting very sick from COVID-19, treatment may be available. Contact a healthcare provider right away after a positive test to determine if you are eligible, even if your symptoms are mild right now. You can also visit a Test to Treat locationexternal icon and, if eligible, receive a prescription from a provider. Don’t delay: Treatment must be started within the first few days to be effective.
