Answer:
If your mask touches another part of your body that is potentially contaminated with the virus—hair, forehead, hands—and the mask is put over your mouth and nose, you are at risk for infection.
Always be sure to wash your hands before putting your mask on, and once it is in place and you are out in public, don’t keep touching or adjusting it. When you’re not wearing it, don’t leave it around your neck in case there was any type of contamination.
