CDC recommends that everyone 2 years and older wear a face mask that covers their nose and mouth when they are in public spaces. Face masks should NOT be put on children younger than 2 due to danger of suffocation. Children younger than 2 years of age are listed as an exception as well as anyone who has trouble breathing or is unconscious, incapacitated, or otherwise unable to remove the face covering without assistance.
Wearing face masks is a public health measure adults and children over 2 should take to reduce the spread of COVID-19. Face masks should be used in addition to (not instead of) social distancing and proper hygiene.
Medical face masks and N95 respirators are still reserved for healthcare personnel and other first responders.
