Years ago, I said forcing kids maskless back into classrooms would cause infections and spread of #COVID19. I was told kids wouldn't be spreaders. Research from France during Omicron found "Children aged 10 to 19y played the greatest relative role in propagating Omicron epidemics, particularly when schools were open, followed by children aged 0 to 9y." With COVID mutating, immunity fading & kids still maskless in schools, will we get serious about safe air in classrooms?

@augieray So if we start with the infectiousness of Covid, maybe 10 resting breaths is infectious, take a classroom of 36x24x8 yielding 6900 cuft, what ACM would stop or slow transmission? If we put 1 CR it takes 8 minutes. 8 box yield 1 minute and turbulent air. Those infectious exhalations are still going to get around to many if not all the other kids in there in either scenario. So clever people will have done this math and will not push their political and financial capital on failure.
@zephyrleifrenner Nothing is 100%--not masks, vaccines, ventilation or filtration. But giving up because something isn't a perfect solution is why we have the issues we do. If you search, you'll find plenty of evidence that air purifiers do, in fact, make classrooms much safer. https://www.brusselstimes.com/243591/air-purifiers-in-classrooms-greatly-reduces-risk-of-covid-19-infections-study-confirms
@augieray @zephyrleifrenner I feel like most everything you could ever want to know about the subject is covered here:
