The Centers for Disease Control and Prevention recommend that all people, regardless of vaccination status, wear masks in certain indoor public places as the nation continues to see growing coronavirus cases.
This new recommendation is for parts of the U.S. where coronavirus cases are surging, as well as everyone in K-12 schools, CDC Director Dr. Rochelle P. Walensky said at a press conference Tuesday.
“This pandemic continues to pose a threat to all Americans,” Walensky said while stressing the risk posed by the highly transmissible delta variant, which is predominant in the U.S.
The delta variant behaves differently from past COVID-19 strains, with new scientific evidence showing that some vaccinated people infected with the variant may be contagious and able to spread the virus to others.
“This new science is worrisome,” she said, later adding that the “vast majority” of infections are still occurring in unvaccinated people.
Walensky cautioned that if the virus is allowed to spread, it will continue to mutate and could eventually evade our vaccines. This could be “just a few mutations away,” she said.
