I'm recanting my previous statements. I'm disappointed how few people are wearing masks today compared to just yesterday. Masks should remain mandated IMO.
I stumbled on this. It's a very interesting explanation of the math behind masks and how it reduces infections in mathematical models (and how changing the variables changes the outcomes, which is not always an intuitive result). The YouTube videos imbedded are very helpful if you prefer to watch over reading, although the text goes into considerably more detail and lets you interactively manipulate the input numbers.

The basic gist is that if 50% of people wear a mask that's 50% effective, it *could* result in 75% less transmissions overall. That's pretty astounding, actually.
Some other food for thought too... I read yesterday that if a COVID vaccine is as effective as a flu vaccine, it will only be about 50% effective, at best. Mask wearing, even without a vaccine, generally achieves substantially higher protection.
The basic premise was don't count on a vaccine saving us. In the meanwhile, wear a mask.
