Original Note:
Cloth mask use has history going back a century or more. Medical grade masks work best, but a proper cloth mask that is kept clean offers some protection and helps dampen the exhalation of virus containing droplets. Medical grade masks can be expensive and in short supply. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7510705/
