Wearing a non-medical mask can be an additional measure you can take to protect others around you, even if you have no symptoms. It can be useful for short periods of time, when physical distancing is not possible in public settings such as when grocery shopping or using public transit.

A mask can reduce the chance that others are coming into contact with your respiratory droplets.
