The only place a face covering helps is in large droplet transmission. Sneezing, Coughing, etc. Even then it fails to stop the small, arosolized, viral droplets. These are the droplets that seed deep in your lungs and cause infections. Masks are less than 30% effective and then only for the person who is ill as this mask fails to stop virus inhalation around the unprotected sides of the mask.
