Opening schools when things are getting worse doesn't seem like such a good idea especially for kids in America. Children especially little ones are expected to keep on masks for hours when it's difficult for them to sit still in a chair for 5 minutes. They're going to cram hundreds of students in one building which makes it easier to spread. It isn't worth the risk and staying home and doing online school until places contain the virus better.
I totally disagree they should open now , kids can spread the virus and I think for now until things get better and numbers go down and there is a really good plan for opening schools then can we only open, but remembering that the virus is still around and that we need to take caution for our schools during this time.
I think the worst decision taken by governments is to reopen schools for the mainstream public.
That said, if there are kids who wish to go back then they should be allowed to do so.
