These recommendations are based on CDC recommendations for preventing respiratory illnesses - like COVID-19, flu, and RSV - in most people. The updated CDC guidance (March 2024) provides a unified approach to addressing risks from these common respiratory viral illnesses.
You may need to work with people in your household and follow additional policies and guidance for other settings (like employer, school, nursing home, daycare, and/or government).
If you or people in your household are at high risk for serious illness from respiratory infections, ask your healthcare provider about more ways to stay protected.
