What is a face mask?


A facemask is used in medicine as a physical barrier worn on the face to protect against the spread of diseases through liquid or airborne particles. A mask may be termed as a dental, surgical, isolation or laser mask. A face mask helps block large-particle droplets, splashes, sprays or splatters that may contain germs (viruses and bacteria), keeping these from reaching the mouth and nose of the wearer. Face masks may also be worn by a diseased individual to help reduce the exposure of their saliva and respiratory secretions on others. Face masks may also be worn to protect oneself from pollution or dust in the environment. It should be noted, that though a face mask provides protection from large droplets, splashes, splatters etc., it does not completely prevent the passing through of microscopic particles present in the environment. A face mask is not to be either shared or re-used. Face masks are loose-fitting masks that cover the nose and mouth, and have ear loops, ties or fastening bands that clasp behind the head. A face mask may be used by a health care worker or by the general public to avoid chances of cross-contamination.
