I won't be sending mine back anytime soon. But I don't think schools will reopen soon anyway. It's fairly clear we haven't yet reached the peak of hospitalisations, so it would be madness, even for a government that doesn't seem to care much about human life or even for the facts. But if they try, I think teachers will decline to put themselves in the firing line in sufficient numbers for it to work. That is after all why most schools in England, at least, closed when they did.
My guess is that it will be September and I'll be looking at the situation and making my own decision when we get to that point, e.g. at the infection rate (if it can be discerned from the number of tests being done by then), the state of things in the hospitals, what is known by then about immunity and ability to be reinfected, whether or not a treatment has been approved and is available, etc. If I'm unconvinced going back is wise, I'll probably keep my ds13 at home, as his education is at a less vital stage and his opportunities (and inclination) to be hygienic less good. But I'll send my ds17 in, as his education is at a really important stage and he has much more control over what he does, where he goes, who he mixes with, and can be trusted to exercise good hand and face hygiene.
Anyone who thinks the government can be trusted to make the best decision based on 'the science' might like to listen to this panel discussion, hosted by Paul Mason and Afua Hirsch, which features a rather different more knowledgeable kind of expert from that in favour at the moment: .
