Wondering about the data behind new CDC guidance on schools, like what data support 6’ vs. less than 6’ with masks? What do other organizations say about using case counts or test positivity to decide when in-person learning is safe, and based on what data? 1/n

What about the safety and effectiveness of masks for kids? How to practically implement screening in schools? Possible impact of new variants and vaccines? The 2/13/21 COVID-19 School & Community Resource Library is online. https://globalhealth.massgeneral.org/covidlibrary.pdf. 2/n

All updates since 1/27 marked in yellow. These particular questions are flagged in sections 4, 11, 17, 19, 21, and 22. A huge thanks as always to the author team and hosting/supporting orgs. 3/n
