It is not as critical because the incidence of death or serious complications arising from SARS-CoV-2 infection are so much lower than with adults, and as you see in the studies, masks aren't all that effective with students. I let your earlier comment go about masks being 37% effective against original COVID meaning they would also be 37% effective against Delta, but that isn't how it works. Most reputable studies I've read put Delta at twice as transmissible as the original. You can pretty much cut the 37% and 21% in half with Delta. There are studies that put the number even lower than that but they haven't been published by the more prestigious journals and I can be a bit of a journal snob.Yet, I'm sure you agree that student-student paths also need to be controlled, right?
If you were curious, here is one that came out yesterday that put the effectiveness of surgical masks at 11% in a study out of Bangladesh.
