One thing has jumped out at me from recent studies of transmission in schools: The seeming rarity with which students transmit the virus to school staff. This should be reassuring to teachers and other staff. Here are some findings: (1/5) 
11 school districts in North Carolina over 9 weeks of in-person instruction: Among 90,000 students and teachers there were 32 infections determined to be acquired within schools. NO instances of child-to-adult transmission were reported (2/5)

17 rural K-12 schools in Wisconsin over about 13 weeks in fall (with VERY high community transmission). Among some 5,500 students and staff, there were 7 reported cases of in-school transmission, ALL among students (3/5) https://www.cdc.gov/mmwr/volumes/70/wr/mm7004e3.htm
Two K-12 independent schools that did regular universal testing throughout fall semester: Among 3,520 students and staff, several instances of in-school transmission, but NO identified student-to-staff transmission (4/5) https://www.medrxiv.org/content/10.1101/2021.01.26.21250065v1.full.pdf+html
Experts at Children's Hospital of Philadelphia have also said that, even as school-related clusters increased over the fall, "student-to-teacher transmission was much less frequent than transmission between students, or between staff members" (5/5) https://policylab.chop.edu/blog/covid-19-outlook-returning-holidays-beset-new-challenges-and-new-solutions
