At medium status, anyone at high risk of getting seriously ill should wear a high-quality mask or respirator, such as an N95, when in public indoors. Additionally, if you have contact with someone else at high risk, consider self-testing to detect infection before contact, according to the CDC.

At a high community level, the CDC recommends everyone, regardless of vaccination status, wear masks in public settings.

The following precautions are recommended at all three community levels - "low," "medium" and "high" - staying up to date on vaccines, including boosters, avoiding contact with those who have a confirmed or suspected COVID-19 case, following recommendations for isolation if you have COVID or suspect you've gotten it and following recommendations for what steps to take if you are exposed.
