I am hearing mixed information about wearing a mask. Fouci says it is not needed provided you are keeping that six foot distance and you do not have the virus but that seems to be changing a bit. Also hear that mask if worn may be worse than not wearing if you fiddle with it as the primary mechanism for transfer is contact/touching. Not saying it is not transferred by aerosol droplets just that it is secondary. Guidance seems to be wear it if you want but be careful.
I am not a doctor but I play one on Nukeworker.

these are not fit tested for the average joe on the street,....
they're not just one time use, they're one time touch to apply, and then only touch one more time to remove and discard,...
these masks are a psychological band aid for the masses,...
a best PF of 10 for professional care givers who know and fastidiously implement the rules of
minimizing cross contamination,...c'mon, we do cross contamination minimization for a living,...we're the LAST people who need this dust mask conversation,....
