I actually saw a handful of NYC people wearing masks - most of them in useless "surgical-style masks". Every time I saw a caregiver w/child, no masks, I stopped myself from yelling at the adult.
>In a room w/ COVID, surgical "masks" protect you for five (5) minutes.
>In that room, in a N-95-style mask, you're protected for fourty-five (45) minutes!
