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.
Masquerade masks were worn by the prosperous class at balls. Masquerade masks had many uses including hiding one's identity, expressing one's freedom of speech, and voicing one's emotions and opinions without judgement.
