Surgical Masks
As its name suggest, surgical masks have been initially meant to be used throughout a surgery. The use was to make sure that the room could possibly be saved sterile, and that germs from a doctor or nurse’s mouth or nostril wouldn’t contaminate the patient. Over the previous couple of years, it has seen commonplace use especially in places like China.
