There is a data indicating masks are not effect source control for respiratory illnesses.

I think the single study that supported cloth face coverings of no particular standard of performance was a mechanistic study that depends on the belief that respiratory illness spread is a direct function of the distance water droplets of an arbitrary threshold size travel from a simulated sneeze. Which, of course, is so obviously true it needs no supporting evidence.

Except it turned out to be false, the primary mode of transmission for sars-cov-2 is aerosols that can spread throughout a room (hence the need for good ventilation), not droplets that quickly fall to the ground (which was what social distancing and masking was predicated on).

I may be reading it wrong, but I believe they were being sarcastic with that last sentence.
