Why a cloth mask?

The CDC (Centre for Disease Control and Prevention) in America recommends that everyone should wear a cloth face cover when around other people.

Cover your mouth and nose with a cloth face cover when around others

• • • You could spread COVID-19 to others even if you do not feel sick.
    • Everyone should wear a cloth face cover when they have to go out in public, for example to the grocery store or to pick up other necessities.
      • Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
    • The cloth face cover is meant to protect other people in case you are infected.
    • Do NOT use a face mask meant for a healthcare worker.
    • Continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.

Masks of any kind do not replace the other actions which reduce the risk of coronavirus transmission, including hand washing, physical distancing and not touching your face.
