For the rest of us who aren't healthcare workers, homemade cloth face masks can help alleviate transmission of germs in general and remind us not to touch our face. When everyone wears masks, those of us who may be infected with the virus but don't show symptoms (asymptomatic) can contain our droplets and lessen the risk of infecting others. If everyone did that, we could make a big difference in transmission. And when healthcare workers need to protect their medical masks, a cloth mask can help extend its use.
Anyone with basic sewing skills, some 100% cotton cloth (sheets, t-shirts, etc.), and a sewing machine (or time for hand-sewing) can make a face mask. Make masks for your own use, or donate to others. #medicalmaskforce #millionmaskchallenge
