DHEC continues to strongly encourage everyone who learns or works in a school setting to wear a well-fitting mask consistently and correctly when around others. Choose a mask that has two or more layers, completely covers your nose and mouth, and fits snugly against the sides of your face and doesn’t have gaps. The CDC has additional mask guidance here.
A proper fitting KN-95 mask is ideal in non-healthcare settings, but not everyone has this type of mask. The key thing to remember, is to consistently wear a well-fitting mask to prevent the spread of COVID or its variants.
