Last week Governor Pritzker and the CDC recommended that all people wear face coverings when going outside.
N95 masks and surgical grade masks should be reserved for healthcare workers. For everyday use, you can make a face covering using an online pattern or with a scarf. The face covering should cover your nose and mouth and should be relatively snug to the face. Be sure to wash your covering between use and do not take it on and off while using it. Face coverings are to enhance, not replace, other social distancing practices. Please be sure to maintain a 6ft distance between yourself and others, avoid touching your face, and wash your hands often. The CDC has developed an FAQ here.
