> Later there were some evidence that it can become aeresol in some high concentration situations like hospitals, but for all practical purposes in everyday life its droplet.

That's not true. There are good studies, followed up with full contact tracing in the environment it happened in, that show aerosol transmission in everyday situations (such as planes and restaurants)

Additionally on the poor fitting masks, triple layer surgicals are more effective (not effective enough) when double masking (which that situation is surgical first, cloth second.. this is the same as using a mask brace to ensure a tight fit)

However, the findings from Aaron Collins found that yes, they are better with a mask fitter.. but they still fail to qualify at the same level as an N95, KN95, or KF94 level of protection. (Those are the levels of protection you require when dealing with airborne based contaminants) On top of that it made it more difficult to wear.

That was later yet. At least in the public mind - some leaders who should know better were saying things that they should have known were false.
