      Yet another paper arguing that mandatory masking protects against COVID... you CANNOT do a randomized trial, so this is a natural experiment. BUT THE EVIDENCE KEEPS ACCUMULATING ...https://voxeu.org/article/unmasked-effect-face-masks-spread-covid-19 …

      2011's https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3285078 … wasn't double-blind but did have no-masks group for comparison to the has-masks group.

      Yes but different disease. But more importantly, source control can't be measured at the individual level, you need a population level variable. It's like air pollution not a drug one takes. So you'd need randomization between communities. Hence the value of natural experiments.

      Same viron size, same infection mechanism though. You’re right about bigger trials needed. As we stand right now we can observe whole countries. Ghana is the late “game of masks” player I’m watching (rooting for) personally. That &sewing high spec masks https://fu-cv.blogspot.com/2020/07/high-filtration-cloth-mask-with-ribs.html …

      Countries that took flu-like protections are doing worse than countries that treated this like SARS tbh, not sure we can say same infection mechanism. So many differences, and emerging. In any case, we are going to go with natural experiments with this necessarily.

          My only position has been “masks for all” since Feb. That *ahead* of singing happy birthday twice. Flu, C19, SARS covered, I think.
