Wonderful article that puts 3 feet vs 6 feet issue to rest in schools (e.g. 3 ft fine for distancing if teachers not vaccinated, then likely less). WHO recommends 1 meter for distancing (3.28 ft), rumor is we miscalculated that to 6 feet! Study from MA

that looked at public schools in the state that opened with any in-person learning in fall 2020. Data was from publicly available district infection control plans & variables of interest were school model type (full in-person or hybrid), physical distancing of ≥3 versus ≥6 ft,

masking policies, ventilation upgrades if done and (sigh) disinfection protocols even though this is spread by respiratory route and not surfaces. Because of practicality in public schools, minimum of ≥3 feet of distancing often put into infection control plans. SARS-CoV-2

positivity examined 9/24/20-1/27/2021 from school data; community incidence rates also known. Among 251 eligible school districts, 537,336 students & 99,390 staff attended in-person instruction during the 16-week study period. Student case rates with spacing of 3 vs 6 ft similar

even when adjusting for community incidence. Same with staff case rates. So, ≥3 feet distance can be easily adopted in public schools now if there is any remaining barrier there (≥ 6 ft not required) after this excellent study in this top ID journal. Write your city/state DPHs
