LOL @ "well documented". No it's not. Its a guess. A theory. To you, that's "well documented" when it works to your narrative, and "misinformation" when it doesn't. Right, so tourism causes COVID spikes. That explains Florida's spike!
Evidence is emerging, doncha know. Some of us knew this way back before the CDC changed their guidance to pretend it does work.
Yet surgical masks pictured in the tweet are effective. And I will note that multiple studies of cities showed that mask mandates were effective for the 1918 flu -- and the cities which controlled the disease better had better economic outcomes.
Most non-idiots (or non red hats) figured out two years ago that most non n95 masks don't filter out virus of a certain size. They also figured out virus travel in microdroplets which do get trapped by some masks, and that the biggest impact is in disrupting airflow during exhalation/inhalation. Hence why the preferred gater worn by redhats does fuck all.
There information about masks and the 1918 flu has been posted numerous times in the past. You really should go educate yourself.
