1/ Schools & COVID-19

A lot of misinformation on this. Best evidence: there is considerable transmission in schools.

So schools should be opened only w/ low community transmission, and w/ mitigation measures: high-quality & well-fitted masks, less density, ventilation, CO2...

2/ If you are interested on this topic, I highly recommend following two experts that have been doing rigorous work:

@DrZoeHyde, e.g. this thread: https://twitter.com/DrZoeHyde/status/1336612124835995648?s=20

3/ Also follow Deepti Gurdasani @dgurdasani1, for example this thread: https://twitter.com/dgurdasani1/status/1346362159446577154?s=20

4/ In terms of how to manage schools in practice, follow @j_g_allen of the Harvard School of Public Health. They have published many excellent resources, such as the Schools for Health website: https://schools.forhealth.org/ 

5/ For information on how to mitigate airborne transmission (most likely the main mode of transmission, both in close proximity and shared room air), see our scientist's FAQs:

6/ Now that @nature seems to have shamed @WHO into admitting that transmission "GOES THROUGH THE AIR", we can hope that clearer guidance may be coming from them. https://twitter.com/HuffmanLabDU/status/1357047539741065216

7/ This is the extraordinary @nature editorial, which might have prompted the admission by @WHO: https://twitter.com/EricTopol/status/1356765668750712832
