Here's another study conducted by Stanford/Yale and other fine institutions, which I actually posted

months ago...be sure to view the 1-1/2 min. video at the end...

350,000 participants from 600 village communities...just using 'Surgical Masks'...not even N95s...not even carefully trained and monitored for usage...imagine how much better the results would be if all of them were given N95s and careful training.
