A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment.

If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain viruses and bacteria, keeping it from reaching the wearer's mouth and nose.

Surgical masks may also help reduce exposure of the wearer's saliva and respiratory secretions to others that could otherwise travel up to 26 feet.

Surgical mask also reminds wearers not to touch their mouth or nose, which could otherwise transfer viruses and bacteria after having touched a contaminated surface.
