2) The study included 61 school districts (kindergarten through grade 12) that provided data from July 26, 2021, through Dec. 13, 2021, a period encompassing the Delta surge and preceding the Omicron surge.
3) In total, there were 40,601 primary infections acquired in the community (36,032 among students, 4,569 among staff) and 3,085 secondary infections acquired in school (2,844 among students, 241 among staff).
4) Of these school districts, six districts (10%) had optional masking policies; 9 had partial masking, i.e., policies that changed during the study or only applied to certain grade levels (15%); and the remaining 46 districts (75%) required masking for the entirety of the study.
5) You know what country doesn’t require masks in schools? England 🏴. You know which country has a shitshow of a COVID situation right now again with cases and hospitalizations both up? England 🏴. 👇

6) NOW would be a very good time to put masks back on & turn on HEPA filters and ventilate indoor public spaces. 👇
