KEY POINTS
  • The CDC recommended that fully vaccinated people begin wearing masks indoors again in places with high Covid transmission rates.
  • The updated guidance comes ahead of the fall, when the delta variant is expected to cause another surge in new coronavirus cases and many large employers plan to bring workers back to the office.
  • Experts say Covid prevention strategies remain critical to protect people from the virus, especially in areas of moderate-to-high community transmission levels.

The Centers for Disease Control and Prevention recommended Tuesday that fully vaccinated people begin wearing masks indoors again in places with high Covid-19 transmission rates. The agency is also recommending kids wear masks in schools this fall.

Federal health officials still believe fully vaccinated individuals represent a very small amount of transmission. Still, some vaccinated people could be carrying higher levels of the virus than previously understood and potentially transmit it to others.
