Not hard to understand the concept- only it doesn’t work in the general public.
Apparently-CROSS CONTAMINATION is a hard concept for you to understand
Masks actually increase the spread due to cross contamination. Your articles made that point and they were also based on healthcare workers dynamics, where infection control protocols are followed, not general public use where no one knows or follows proper infection control procedures.
Your so-called studies have a lot of suppositions-MAY, POSSIBLY, SOME, those are words used in an attempt to qualify an opinion not substantiate a scientific fact.
I’ve had over 25 years of infection control protocols and actually used the protocols in healthcare settings on a daily basis.
So tell me jackass- how much do you know? You can’t even understand the information you sent me.
