Hand scrubbing is good, but also not all that effective since the primary means of infection is droplets. So the #1 defense that kept you healthy and keeps others healthy, is masks. Which many schools will not be requiring. The second is social distancing, which in the younger years, many schools will also not be requiring within their "bubble" (keeping in mind the bubble could be anywhere from 15-60 kids depending on class size and then how many classes are in the bubble, and that all those kids in the bubble are being exposed to many people outside of school). Temperature checking isn't being proposed here, either.
The return to school is really a very different scenario than going to eat on a patio or running into Canadian Tire for half an hour, or even your job where you had hand washing, masks and temp checks.
To me, I think one of the most important things school can do this year is take learning outside as much as possible, then require face shields and/or masks while indoors. Parents could easily start working with their kids now re: wearing them, especially learning not to fidget with them. I'm thinking face shields for teachers and students would be better for K-2, for the purpose of learning to read, social skills learning etc... Not as good as masks, but better than nothing. Then have a hand wash station set up in each K-2 classroom, so kids can wash their hands with soap regularly, since those ages are the slimiest lol. By grade 3/4, most schools have moved past learning to read to reading to learn, so masks would be fine, though I think face shields will always be better for teachers since some kids are always going to rely on seeing what they are hearing. I also think they should be screening everyone (temp check), every day. While temp checks are useless for the asymptomatic cases, even if they catch just a few cases, that could go a long way towards stopping a local outbreak.
I know many places are starting to do throat swabs instead.
