These breathing droplets travel in the air and can then land in the noses and mouths of others, which spreads COVID. Therefore, to be effective, you wear a face mask correctly over the nose and mouth.

Ensuring that masks fit nicely on the face is very important to help prevent getting and spreading COVID. A common problem with some face masks is that there can sometimes be gaps between the face mask and your face. When there are gaps, air with respiratory droplets containing the virus can leak in and out around the edges of the face mask. It helps prevent air leakage; covers should fit snugly against the sides of the face and not have gaps.
