Do Medical Masks Match N95s for COVID Protection in Healthcare Settings?
November 29, 2022
Roger Chou, M.D., provides outside expert commentary on a randomize trial that found medical masks fall “within predefined margins of noninferiority” against N95 respirator in protecting against COVID. Chou says that the trial offers the best evidence thus far on masking effectiveness among healthcare workers providing routine patient care, it “results are not definitive” and “indicate that medical masks may be similar to N95 respirators in Omicron-era settings with high COVID-19 seroprevalence.”
