Why should people wear masks?
Masks are a key measure to suppress transmission and save lives.
Masks should be used as part of a comprehensive ‘Do it all!’ approach including physical distancing, avoiding crowded, closed and close-contact settings, good ventilation, cleaning hands, covering sneezes and coughs, and more.
Depending on the type, masks can be used for either protection of healthy persons or to prevent onward transmission.
