The point is that people are arguing that schools need to be closed lest they become a hotbed for virus spread. But if that were actually the case, if schools indeed serve as important infection vectors, then teachers would contract it at a significantly higher rate than other professions do. This data is a very strong indication that the assumption that schools are hotbeds for covid transmission is just flat out wrong.Doesn't take into account asymptomatic spread to families, etc. Also, great, they got sick just like everyone else? What's the point here? They wouldn't get sick if schools were closed, thus lowering the level of spread of the virus.
If schools do, in fact, not serve as considerable infection vectors, then the marginal benefit of keeping them closed is not worth the major drawback of harming children's development
