SURGICAL FACE MASK

surgical mask, also known as a procedure mask, medical mask or simply as a face mask,[1][2] is intended to be worn by health professionals during surgery and during nursing to catch the bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose. They are not designed to protect the wearer from inhaling airborne bacteria or virusparticles and are less effective than respirators, such as N95 or FFP masks, which provide better protection due to their material, shape and tight seal.

Surgical masks vary by quality and levels of protection. Despite their name, not all surgical masks are appropriate to be used during surgeries. Surgical masks may be labeled as surgical, isolation, dental, or medical procedure masks.[3]Chinese health officials distinguish between medical (non-surgical) and surgical masks.[
