Why Masks Work BETTER Than You'd Think (youtube.com)

This video is about how masks (whether surgical, or N95, or cloth) are counterintuitive and actually work much better epidemiologically than one might expect. Masks do double-duty, and the fraction of interactions with masks is much higher than the fraction of people wearing masks, so partially adopted, partially effective masks are able to reduce the basic reproduction number surprisingly well.

    Francisco Gimeno - BC Analyst A simple and useful explanation on why we use masks during these troubled times. Yes, there are many questions yet, many "ifs" and theories which make the use of masks a point of contention for political, power or just control reasons. We are however afraid we are going to get used to be with masks around not just now but for the near future. Better to be informed.
