Face masks can reduce your chances of getting SARS-CoV-2, but the primary purpose of face masks is to protect others from you in case you are infected, especially if you are not showing symptoms. It is recommended that the public wear well-fitting multi-layer cloth masks, including homemade masks, to help prevent transmitting the virus to other people. You may also want to consider wearing 2 masks, which can offer additional protection if your mask is a little loose and doesn’t fit snugly around your nose and mouth. 4
