What does a mask or a face covering do?
A mask or face covering acts as a barrier. It reduces your risk of spreading and getting COVID-19. A well-fitted mask or face covering can protect others from potential COVID-19 droplets you may spread and prevents you from breathing in infectious respiratory droplets from others.
Wearing a mask or face covering, along with other personal protective measures such as staying up to date with all recommended COVID-19 vaccines, hand washing, physical distancing, and staying home when ill, can stop the spread of COVID-19.
