The WHO has guidelines that recommend health care workers cover their mouth and nose with surgical masks and the CDC put out instructions for health care workers to wear N95 masks. N95 masks are thicker and fit more snugly around the mouth and nose, blocking smaller particles than surgical masks. Both types of masks help prevent the spread of droplets from a cough or sneeze from reaching the mask-wearer’s mouth or nose. During the SARS coronavirusSARS coronavirus outbreak a study found that any type of mask or respirator reduced the risk of infections in health care workers by 85 percent. The CDC recommends that health care workers wear a respirator, also called an N95 mask, when around potential COVID-19 patients, which filters out more particles than a surgical mask. The CDC has a list of N95 masks approved by the National Institute for Occupations Safety and Health (NIOSH).
