Face masks (or other face coverings that cover your mouth and nose) are one of the most effective measures that help reduce spreading of the virus. The face covering helps to avoid spreading of the virus by stopping the respiratory droplets which contain viral particles.
Face masks are only effective when worn correctly – over your nose and your mouth.
Face masks are used to prevent spreading of COVID -19 and are recommended by sufficient professional organizers including the World Health Organization (WHO). To cover your mouth and nose, it is recommended to use face masks (either medical or textile masks), respirators or scarves.
