N95 Respirators Recommended for all COVID-19 Encounters
Guidelines for face protection required for workers caring for COVID-19 residents have been expanded to recommend N95 respirators versus medical masks. According to a report published in the Annals of Internal Medicine, current guidelines are based on unreliable and unsupported data that medical masks are equivalent to N95 respirators in reducing infection risk.
While N95 respirators have been recommended during aerosol-gathering procedures, the investigators outline the risks associated with all resident encounters. Their data suggests that since the risk for infection is tied to the duration and magnitude of exposure, then multiple people coughing and breathing will expose care providers to droplets, resuspended droplets, as well as aerosols. The investigators concluded that N95 respirators achieve better filtration of airborne particles than medical masks if used properly.
