CDC: Vaccinated people should now wear masks in high transmission areas

The Centers for Disease Control and Prevention (CDC) on Tuesday essentially reversed earlier COVID-19 guidance by saying fully vaccinated people should now wear masks in certain situations.

The agency said fully vaccinated people should wear masks in "public, indoor settings" in areas of the country with "substantial" or "high" levels of transmission, as defined by the CDC. Those areas currently include much of the South and West.

The CDC also said all adults and students should wear masks in K-12 schools regardless of vaccination status.
