Well, imagine my shock that school districts in Colorado requiring masks have lower COVID transmission. How much lower if they also used good ventilation, HEPA filters, outdoor lunch, etc. (1/x)

2/ @CDPHE data via @johningold showing COVID cases for school-age kids in #Colorado districts w/ mask mandates (blue) are lower than those w/o mandates (orange). Yellow bar shows in-person school return.
But 6-17 yr cases very different at county level, so these wrap together.

3/ More data from @CDPHE via @johningold. Overall, COVID cases in 0-5 & 6-11 yrs age groups (no vax approval yet) still hovering near their peak levels as a Colorado state average.

but, until school-aged children in the state (and everywhere) have widespread access to being fully vaccinated, schools and the rest of society owe it to them and ourselves to apply reasonable prevention strategies.
