Wearing a mask will change everything about the epidemic, that is the big lie currently being told by our political leaders. Look, here is a great example–Memphis. See how much cases declined when both the city and county imposed mask mandates. (Thanks to T. Heller for the chart.) And please, go to Worldometers or whatever site you prefer and take a look at what is going on in Japan and other Asian countries, where mask-wearing has always been close to a religion. Coronavirus doesn’t care, at all. And we have a sense of why now. Masks aren’t perfect, and it appears that the dose needed to infect is so small, and the binding affinity to the receptor so high, that any leakage or other issue is all the virus needs. So wear ’em if you want to but let’s stop the mass delusion that they are the magic pill for the epidemic. Oh, and did I mention that the epidemic is basically over in Sweden, where no one wears a mask.
