A large number of bacteria are adsorbed on the outside of the mask. When removing the mask, avoid touching the outside of the mask. Hold the lace with your hand to remove it to prevent the bacteria from adhering to the hand and spreading with the hand as a medium.
When we take off the mask, there are a few points to remind everyone:
✘Do not touch the outer surface of the mask, because you may infect yourself.
✘Do not touch the inner surface of the mask (self is a patient), because it may infect others.
✘Do not touch the masks used by others because they may cross-infect.
✘Do not put it directly in bags, pockets, etc., because there may be a risk of persistent infection.
