Original Note:
Secretary Cardona, I was the senior author of this study. Our study is not able to give any information about the role masks played in the observed low in-school transmission rates. We had no control group so don't know if the rate would have been different without masks. https://twitter.com/TracyBethHoeg/status/1442710250830774274?s=20
