Agency recommends masks for all in public indoor settings as Delta variant rages on

The CDC now advises fully vaccinated people wear a mask in public indoor settings where there is “substantial or high transmission” of Covid-19 B.1.617.2 (Delta variant) circulating in the United States. This is an update to its current guidelines.

“In recent days I have seen new scientific data from recent outbreak investigations showing that the Delta variant behaves uniquely differently from past strains of the virus that cause Covid-19,” CDC Director Rochelle Walensky, MD, said during a media briefing on Tuesday, CNN reported.

“This new science is worrisome and unfortunately warrants an update to our recommendations,” she added. “This is not a decision that we or CDC has made lightly.”

The primary driver, CNN reported, is that vaccinated people can be infected with the Delta variant and can “still play a small role in transmission,” though breakthrough infections remain rare. The Delta variant comprises at least 83% of cases now, compared with 1% of reported infections in May of this year.

The agency also noted that those who are fully vaccinated “might choose to wear a mask regardless of the level of transmission, particularly if they are immunocompromised or at increased risk for severe disease from Covid-19, or if they have someone in their household who is immunocompromised, at increased risk of severe disease, or not fully vaccinated.”

The CDC is also recommending that fully vaccinated people with a known exposure to someone with suspected or confirmed Covid-19 be tested for the virus 3-5 days post-exposure. These individuals should also wear a mask in public indoor settings for two weeks or until their tests come back negative for Covid-19.

Lastly, “CDC recommends universal indoor masking for all teachers, staff, students, and visitors to schools, regardless of vaccination status,” the agency wrote.

The American Medical Association issued a statement supporting the CDC’s move. AMA President Gerald E. Harmon, MD, said, “With cases of Covid-19 continuing to increase in the United States and a significant number of people who remain unvaccinated, the CDC’s updated mask guidance is needed to help curb the spread of Covid-19—particularly the Delta variant, which we know is much more contagious.”

He added that the association strongly supports the revised guidance and noted, “Wearing a mask is a small, but important protective measure that can help us all stay safer. The AMA continues to strongly encourage everyone who is eligible for Covid-19 vaccines to get vaccinated as soon as possible. We urge anyone with questions about the vaccines to speak with their physician and review trusted resources, including”
