Children should follow the same principles as adults for wearing masks. This includes cleaning hands at least 20 seconds if using an alcohol-based hand rub, or at least 40 seconds if using soap and water, before putting on the mask. Make sure the mask is the right size to cover the nose, mouth and chin. Children should be taught how to wear the mask properly, including not touching the front of the mask and not pulling it under the chin or into their mouth. They should store the mask in a bag or container, and not share the mask with others.
