Masks are mandatory here in New York. I work for a large public transit company and I am out there in public everyday. I'm noticing that people are wearing the typical surgical mask-the one they hand out to you if you go to a doctors office now. With these masks I'm noticing that people now feel comfortable enough to ride on a train, or enter an office where there are others present. My question is, do these masks help the wearer from contracting COVID-19? I am aware it does contain the spread from a person, but how safe are you wearing one for protection?
