Sadly, my takeaway/tl:dr
Everything you've heard or read is fake news, we know almost nothing. Ironically uses 'gone viral' when he crits a fellow doc (cite 12) on the mask 'issue', and clearly we can't even get these experienced pros on this very topic to agree on much of anything, but will print regardless.
Based on my comment's downvotes, and no feedback, I have to assume I've either 1) Misread the article, 2) Misinterpreted the article, 3) Didn't clarify my position sufficiently.
This recent HN post has a pretty good summary of where I think we all are on the given 'mask issue' topic:
Suffice it to say, these clap-back articles among the medical elite in supposed positions of authority don't clarify the facts any better than the sketchy policies being made on nebulous data. But I guess we are in a state of 'real-time' peer review, and everyone left guessing the outcomes.
