How to Wear a Mask?

From the World Health Organization:

How to put on, use, take off and dispose of a mask

• Before putting on a mask, clean hands with alcohol-based hand rub or soap and water.

• Cover mouth and nose with mask and make sure there are no gaps between your face and the mask.

• Avoid touching the mask while using it; if you do, clean your hands with alcohol-based hand rub or soap and water.

• Replace the mask with a new one as soon as it is damp and do not re-use single-use masks.

• To remove the mask: remove it from behind (do not touch the front of the mask); discard immediately in a closed bin; clean hands with alcohol-based hand rub or soap and water.
