How should I wear a mask?
The WHO recommends that you clean hands with alcohol-based hand rub or soap and water before putting on a mask.
Cover mouth and nose with mask. Loop the elastic straps around your ears and adjust the toggles, if available, so there are no gaps between your face and the mask.
After use, remove the mask from behind, loops first. Wash the mask after every use.
