The Centers for Disease Control and Prevention relaxed its mask guidance on Friday, allowing most people to ditch their face coverings so long as Covid-19 hospitalizations in their communities remain low.
Under the new CDC guidance, people are advised to wear masks in public areas indoors, including schools, when there’s a lot of virus circulation in their communities that could overwhelm local hospitals. More than 70% of Americans live in communities where hospitals are not under severe threat from Covid, according to CDC data. That means they wouldn’t need to wear masks in indoor public places, though they can if they want to.
The CDC’s new focus on the impact of severe disease on hospitals marks a significant shift away from the agency’s previous use of Covid infections as the key metric when issuing public health guidance.
“With widespread population immunity, the overall risk of severe disease is now generally lower,” Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, told reporters during a call on Friday. “This updated approach focuses on directing our prevention efforts towards protecting people of high risk for severe illness and preventing hospitals and healthcare systems from being overwhelmed.”
Under the new guidance, masks won’t be required indoors if average new cases fall below 200 per 100,000 residents over the past week and new Covid hospitalizations represent less than 10% of the population. Indoor masking would kick in if weekly Covid admissions exceeded 20% of available beds or if the seven-day average of staffed beds used by Covid patients exceeded 15%.If cases exceed 200 per 100,000, the hospitalization thresholds that trigger indoor masking both drop to 10%, according to the CDC’s new guidance
People are still required by federal law to wear masks on planes, trains, buses and other forms of public transportation.
New York and California lifted mask mandates for indoor public places earlier this month as infections fell, prompting questions about whether the CDC would also change its guidance.
The CDC last made a big change to its mask guidance in July 2021 when the delta variant was sweeping the U.S. At that time, the CDC recommended that people wear masks in indoor public places, regardless of vaccination status, in areas of the U.S. where transmission of the virus is high.
The guidance from the summer remained in place as the more contagious omicron variant displaced delta in December, setting off the largest wave of infection since the pandemic began. However, scientists and public health officials later found that omicron generally doesn’t make people as sick as delta. As infections soared to an unprecedented level, hospitalizations and deaths did not rise at the same rate.
The U.S. is reporting a seven-day average of about 75,000 new cases per day, according to data compiled by Johns Hopkins University, a 91% decline from the pandemic record of more than 800,000 average daily cases seen on Jan. 15.
Hospitalizations have also fallen sharply, to about 57,500 patients with Covid in the U.S. as of Thursday from a high mark of more than 159,000 on Jan. 20, based on a seven-day average of data from the Health and Human Services Department. The daily Covid death toll reached its highest level in nearly a year on Feb. 1 at an average of more than 2,600 per day, and has since fallen to about 1,740, Hopkins data shows.
