We use data from

COVID-19 Symptom Survey https://delphi.cmu.edu/covidcast/survey-results/?date=20210221.">https://delphi.cmu.edu/covidcast... Based on responses throughout the country (A) we see huge differences frequency of in-person schooling (B), the amount full time (C) and the number of mitigation measures reported (D) (2/8)

After adjustment for reported case rates and other covariates we find a significant association between living w/ a child in inperson school and reporting #COVID-19 related. Risk increases w/ grade. We look at two measures of recent symptoms and +COVID test in last 14 days (3/8)
Odds of #COVID-19 outcomes decrease by ~8% w/ each mitigation measure. Symptom screening, teacher masking, and closing extracurriculars stand out. (4/8)
When examine impact by mitigations in place, it looks like ~7 school-based mitigation measures is enough to make household member risk the same as if they were living with kids not in in-person schooling. Likely depends on how well these are implemented. (5/8)
We couldn& #39;t drill in as much on teachers, but we did find that Pre K-12 teachers who reported "working for pay" outside home had an increase risk of #COVID-19 outcomes. The increase was similar to office workers. (food service funny due low at home N) (6/8)
The type of survey and the topic raises lots of concerns about potential confounding and biases. We can& #39;t rule those out, but when we did tons of stratified analyses in supplement and things held up (7/8)
Overall, in-person schooling seems to be associated with #COVID-19 risk to household members, but this risk can be controlled by in-school mitigation measures. A lot still remains unknown, hopefully this study of ~600k people helps folks thinking about this thorny issue. (8/8)
