The Science Is In: Wear. A. Mask!

Back in June, in a post called Jesus Christ, Just Wear a Face Mask!, I presented a bunch of evidence and arguments for wearing face masks to prevent the spread of Covid-19. Even then it was pretty clear that masks were working. In piece published by Nature yesterday, Lynne Peeples summarizes what the data and science currently says about the effectiveness of wearing face masks. Here is her one-sentence summary:

To be clear, the science supports using masks, with recent studies suggesting that they could save lives in different ways: research shows that they cut down the chances of both transmitting and catching the coronavirus, and some studies hint that masks might reduce the severity of infection if people do contract the disease.

And importantly, even ardently pro-mask scientists agree that masks should be worn in conjunction with taking other precautions: limiting large gatherings, maintaining distance, limiting the time you spend indoors with others, etc.
