WHO stands by recommendation to not wear masks if you are not sick
"There is no specific evidence to suggest that the wearing of masks by the mass population has any potential benefit. In fact, there's some evidence to suggest the opposite in the misuse of wearing a mask properly or fitting it properly," Dr. Mike Ryan, WHO executive director of health emergencies program, said during a media briefing in Geneva on Monday.

"In the community, we do not recommend the use of wearing masks unless you yourself are sick and as a measure to prevent onward spread from you if you are ill," Van Kerkhove said. "The masks that we recommend are for people who are at home and who are sick and for those individuals who are caring for those people who are home that are sick."
