After adjusting for race\/ethnicity and socio-economic status, there was no difference in the incidence rates between schools with a \u22653 feet vs \u22656 feet distancing policy among students (aIRR=0.761) and staff (aIRR=0.902). Incidence rates in both students and staff were strongly correlated with community incidence and positive cases in schools, particularly among school staff. <span class=\"Apple-converted-space\">\u00a0<\/span><\/li>\n<\/ul>\n<p><i>van den Berg et al.\u00a0(Mar 10, 2021).
