It has been a big few weeks for data related to schools! Many important new studies came out, and are highlighted in the Jan 27 update of the COVID-19 School and Community Resource Library. https://globalhealth.massgeneral.org/covidlibrary.pdf 1/n

New peer-reviewed reports of low rates of in-school transmission from US public schools in WI and NC, and parochial schools in Chicago, to build on the robust and still-growing body of literature from the UK, Europe, and Australia. @TracyBethHoeg 2/n

An exciting new program announced by MA DESE @MASchoolsK12 to support weekly COVID-19 screening of asymptomatic students and staff in public K-12 schools, and 3/n

..we also want to point to work by Alyssa Bilinski that just missed this update, underscoring the role for screening in schools where community rates are high: https://github.com/abilinski/BackToSchool2/blob/master/5%20-%20Draft/Schools_draft.pdf). 4/n

Updated results from ongoing studies of aerosols from musical instruments and singers, new guidance and data on sports, and brand new sections on vaccines and variants with a focus on schools. 5/n

As always, the latest updates on case counts, testing rates, hospitalizations, and mortality from CDC and AAP. 6/n

Thanks as always to the author team and to @GlobalHealthMGH, @IDSAInfo, http://Covidsafeschools.org , @mgh_mpec, and @mgh_id for hosting and supporting this work. 7/n
