The SF Anti-Mask League of 1919
Is there any reason to believe that gauze masks are even slightly effective against influenza?The flu can stay viable in air for hours, and the individual exhaled airborne particles are vastly smaller than the holes in gauze -- it's "breathable" (allows moisture droplets to pass)I suspect the mechanism of action is inconveniencing people into not leaving home at all, a no-pants order would probably have worked as well or better
