      I'm a co-author (one among many) on this new paper reviewing and synthesizing the strong scientific evidence for how universal masking can reduce transmission (source control) and greatly dampen the spread of COVID-19. It's under review. Preprint here: https://www.preprints.org/manuscript/202004.0203/v1 …pic.twitter.com/Q6CFBfUNgc

      It was an honor to work with so many amazing people on something so important. Check out the team. Also look at this graph modeling the combination of mask efficacy and compliance. (But read the paper! We go through many issues in a realistic overview). https://twitter.com/jeremyphoward/status/1249809098079637512 …pic.twitter.com/Khk49I8gmk

          I want to add a note on how amazing the preprint experience has been. We've received *a lot* of critical feedback. Right now official peer-review is backed up everywhere due to high-volume of papers. But there is also such robust open discussion. Final paper will greatly benefit.

          Just like everything else, there is a lot of not-so-useful feedback (the simplest things that we've obviously thought of and addressed) but also really harsh but on-point stuff. Things we overlooked, a paper that was cited incorrectly, interesting, challenging points to ponder.

          Seeing the sausage made makes some people queasy! How can they be right if they cited a paper incorrectly? (We did!) In reality, everyone makes mistakes, small or big, and the only thing you can trust is a process that tries to spot and fix them. Nobody, no team is infallible.

          And here's the part that just makes me so happy. When we receive criticism, this team's response has been: hah, let's check, are they right, does this need improvement, let's go look at that, let's recalculate, let's add a clarification... As it should be. Iterative improvement.

          Doublechecking I understand the graph and mask efficiency: 100% mask efficiency needs 40% usage to reach R0=1 60% mask, 65% usage 40% mask, 100% usage Reading the paper, the estimate for a home-made cotton mask seems to be 1/3 of 96% ( surgical mask ), so around 30%?

          I think the citation for this chart should be supplemental fig 4 of ref 89 not (ref 7). Congrats to all on this piece. So much more realistic that testing 100M people each week!

          This is a great plot. So important to get ppl out of the flawed binary thinking of mask-good/mask-not-good, protection/unprotected. It's all about nudging the population closer to R<1, and there are no sharp lines here. Just probability scales.

          I also suspect there's a spectrum w/in each individual infected person, and that reducing the dose of virus thru masking probably tends to produce less severe outcomes. But, I know that's harder to model, and needn't be on this plot.

          Thank you @jeremyphoward, @zeynep, et al for this work. Ever more important if this estimate of an R0 of 5.7 for COVID-19 proves accurate. https://wwwnc.cdc.gov/eid/article/26/7/20-0282_article …
