The committee’s next tier consisted of viruses in a “pandemic-phase,” when the pathogen is new and little immunity through infection or vaccination exists. However, in a call with KFF Health News, Kallen clarified that the committee put coronaviruses that cause colds in that category, but not yet the coronavirus causing Covid. “The time has come to deimplement policies that are not appropriate for an endemic pathogen,” they wrote. A surgical mask, rather than an N95, was suggested as protection for a category they created for “common, endemic” viruses that spread over short distances, and “for which individuals and communities are expected to have some immunity.” Three committee representatives, researchers Hilary Babcock, Erica Shenoy, and Sharon Wright, were among the authors of a June editorial arguing that hospitals should no longer require all health care workers, patients, and visitors to wear masks in hospitals. Researchers and occupational safety experts were also perplexed by how the committee categorized airborne pathogens. “The CDC must not undermine respiratory protection regulation by making the false and misleading claim that there is no difference in protection” between N95 masks and surgical masks, commented Deborah Gold, an industrial hygienist at Cal/OSHA, at the August meeting. Her assertion is backed by the California occupational safety agency, Cal/OSHA, whose rules on protecting at-risk workers from infections might be at odds with the CDC’s if the proposals are adopted. “The science of N95 respirators is well established and based on physical properties, engineered filtered materials, and our scientific understanding of how airborne transmission works.” “It’s shocking to suggest that we need more studies to know whether N95 respirators are effective against an airborne pathogen,” said Kaitlin Sundling, a physician and pathologist at the University of Wisconsin-Madison, in a comment following the June meeting. And it contradicts an extensive evaluation by the Royal Society, the United Kingdom’s national academy of sciences, finding that N95 masks, also called N95 respirators, were more effective against Covid than surgical masks in health care settings around the world.

It also excludes a large clinical trial published in 2017 finding that N95 masks were far superior to surgical masks in protecting health workers from influenza infections. Their conclusion runs contrary to the CDC’s 2022 report, which found that an N95 mask cuts the odds of testing positive for the coronavirus by 83%, compared with 66% for surgical masks and 56% for cloth masks. But still, they concluded the masks were equivalent. For example, many health workers who got Covid in the trials were not infected while wearing their masks at work. In June, members of the CDC’s group - the Healthcare Infection Control Practices Advisory Committee - presented a draft of their report, citing studies that found no difference in infection rates among health providers who wore N95 masks versus surgical masks in the clinic. “It is our goal to develop a guideline that is protective of patients, visitors, and health workers.” He added that the draft guidelines are far from final. “We are very happy to receive feedback,” Alexander Kallen, chief of the Prevention and Response Branch in the CDC’s Division of Healthcare Quality Promotion, told KFF Health News. She said N95 masks, ventilation, and air-purifying technology can lower rates of Covid transmission within hospital walls and “help ensure that people are not leaving sicker than they came.” “Health care facilities are where some of the most vulnerable people in our population have to frequent or stay,” said Gwendolyn Hill, a research intern at Cedars-Sinai Medical Center in Los Angeles, after the committee’s presentation. Nationwide, hospital admissions and deaths due to Covid have been increasing for several consecutive weeks. After the meeting, members of the public expressed concern about where the CDC was headed, especially as Covid cases rise. Once the advice is final, the CDC begins a process of turning the committee’s assessment into guidelines that hospitals throughout the United States typically follow. 22, but it postponed the vote until November. The committee was slated to vote on the changes at a public meeting on Aug.
The draft controversially concluded that N95 face masks are equivalent to looser, surgical face masks in certain settings - and that doctors and nurses need to wear only surgical masks when treating patients infected by “common, endemic” viruses, like those that cause the seasonal flu.
