Do face masks slow the spread of coronavirus?
Hand washing and social distancing are your defenses against coronavirus while wearing a mask keeps you from getting others sick.
Coronavirus is a respiratory illness that hitchhikes on respiratory droplets from coughing, sneezing, and talking.1 Without a mask, these droplets can travel six feet or more and potentially infect others around you.
A cloth or fabric face mask can block these droplets and slow the spread. Face masks aren’t foolproof, but they can minimize dangerous airborne particles.
Essentially, the number of particles in the air decreases as the number of people who wear masks increases.
