Heckfire, even the U.S. CDC is now getting into the act on the side of actual evidence-based public health:
And please note the two read arrows that I've added to the graph to draw attention to the reduction in sub-micron aerosols if the receiver alone (i.e. the exposed) doubles up and puts a paper medical mask under a well-fitting cloth one (see 'B' in the upper image).
Of course the best for everyone, always is when, of course, everybody masks up as is clear from all three groups in the graph.
Do it!

Do it!
