I checked several medical sites and they all urge the use of masks, insisting they inhibit the spread of the bug from those who have it to those who don't.
The mask is to protect others, and does help.
But MSNBC has several times had a doctor on who insists masks are useless.
If you stand next to a person who has the bug for one minute you will be infected, masks or no.
Leaves you wondering, eh?
Anyway, I won't be getting a haircut any time soon.
Don't share a car, don't ride a bus, don't get on a plane, etc..
