Yes, agreed, our knowledge in this area has come on leaps and bounds this year though I'm surprised that there wasn't research to hand from the Asian countries that have used face masks routinely.

Is there actually any proof that masks helped in those countries? Or did they simply not too many infected people coming into the country in the first place? Eg A small island/country can either not have a single case or could be completely overwhelmed, depending on whether any infected people go there.
Not going out at all, is preferable to going out with a mask. The masks aren't 100% effective and there is contact transmission. The more people go out, even with masks, the greater the chance they will pick up the virus.
It's only recently that it's recognised that merely breathing spreads it, rather than the previously thought coughing and sneezing. Sneezing and wet coughs are NOT symptoms of Covid-19, but are more generally symptoms of flu.
The previous mask advice was based upon actual studies. They didn't suddenly pronounce it from nowhere.

In conclusion there is limited data to support the use of face masks and/or respirators in healthcare and community settings. The effectiveness of masks and respirators is linked to consistent and correct usage; however, this remains a major challenge – both in the context of a formal study and in everyday practice. This update has demonstrated that new evidence has emerged (primarily for RCTs based in the community), however studies are still few and far between for influenza, particularly within the context of the 2009 pandemic, and there has yet to be any studies examining the behaviour of ‘new’ seasonal influenza (which may behave somewhat differently than the preceding seasonal influenza (50) . Hence continued research on the effectiveness of masks/ respirators and other associated considerations remains an urgent priority with emphasis being on carefully designed observational studies and trials best conducted outside the stress and strain of crises.
