Since we know that a basic cloth mask or scarf doesn’t do much to keep you from getting infected, do you think maybe we are being encouraged to wear masks to help keep asymptomatic people from spreading the C19 virus?
They have always said to wear a mask if you have the virus, so maybe now they are assuming that since some people show no symptoms it would be better to have everyone wear a mask to help prevent them from spreading the virus.
Just my tin foil hat theory for today.

I think that's a reasonable interpretation for the wear-whatever-on-yer-face recommendation.
It is to stop infected people from spreading the disease as easily.

Sewing a bunch this weekend. Found an alternative to regular elastic, which is in short supply - extra thick extra large hair elastics.

The best I've seen on this, can't find it now, is something like:
A good n95 mask will knock out maybe 98% of the likelihood of getting a virus (and remember, if you're distancing, the likelihood of encountering a virus goes way down in the first place!)
A multiple layer bandana maybe knocks the likelihood down 80%? 60%? So not as good as an N95, but much much more than nothing.
There's stuff out there comparing n95 to surgical mask, and maybe to a bandanan, but i don't have time to find --have to work this weekend.

A good reason also is to keep people from touching their faces.

I'm guessing those dust masks you (could) get at the Dollar Tree are maybe a half step above useless? I had a few in the shed. Better than nothing?
