Surgical mask, also known as procedure mask, medical mask or simply face mask, is intended to be used by healthcare professionals during surgery and patient care to prevent bacteria from being transmitted by aerosol and liquid droplets in the user's mouth and nose. It is not designed to protect the wearer from breathing airborne bacteria and virus particles, and materials such as N95 and FFP masks are less effective than respirators that provide better protection due to their shape and tightness.
