When a symptomatic person wears a mask, the chance of infecting someone else is significantly less than if they did not wear a mask. The mask blocks the droplets that contain the virus.
Asymptomatic or pre-symptomatic people are infected and can transmit the virus to others. This is the reason for everyone to cover their faces in public when social distancing is not guaranteed.
