Before everyone starts walking around like billy the kid.
From webmd ...
Cloth masks, like a bandana or handkerchief covering your nose and mouth, trap moisture and can help bacteria and viruses grow.
That article you linked...about not wearing masks/face covers....merely regurgitates what the CDC has been saying about wearing masks.
And, we all know better than to trust the CDC.
Clearly
Don’t
Care
about the masses.
Several of our local safety agencies are saying TO wear cotton (bandana) masks/coverings, to keep conversational droplets (aka spit) from traveling from one person to the next.
Now, how effective are these bandanas at protecting from CV? I’d say at least somewhat better than wearing nothing at all.
How long do you have to wear a mask before bacteria and viruses grow?
