If you can still smell a fart while masked, the masks don't work.
Btw, and I can't remember where I saw it first, but there was a study done in China originally early last year, on COVID-19, that says they knew it passed more easily thru fecal matter than anything else. Which would explain the high numbers if infected among the homeless populations in "fine, liberal run" cities such as Seattle, Portland, NYC, San Fran, L.A., etc.

I'm sure the info is still out there to find.
