The hazards of used face mask

Used face mask may carry a large number of microorganisms, such as viruses and oral bacteria. These microorganisms may not only originate from the outside world, and adsorb on the outer surface of the mask through inhalation, but also may be adsorbed on the inner surface of the mask through exhalation because the user carries bacteria and viruses. Therefore, used masks may have a great risk of infection.

When we take off the mask, there are a few points to remind you:
✘Do not touch the outer surface of the mask, because you may infect yourself.
✘Do not touch the inner surface of the mask (you are a patient), because you may infect others.
✘Don't touch the masks used by others, because it may cause cross infection.
✘Do not put it directly in a bag, pocket, etc., because there may be a risk of persistent infection.
