My family came in in a type of space suit to visit me. Then sprayed down or whatever they did.
I only ever wore a mask in hospitals, Sweden was pretty free on this front.
Asians here were the first to mask, very conformist, for good and bad I guess. I'm not positive but some ssy their immmediate draconian measures did have an effect, they did very well all things considered. Not necessarily because of the masks per se...
