Been thinking about this. How can schools open if the borders are still closed? In China right now they are closing the border again due to returners bring covid19 with them. Schools will only re-open when it is safe to do so. That might be after a vaccine is available. The worst is yet to come. USA, India, Africa are all heading for a very scary time in the next month or so. The death figures will be terrifying and this will change the common view that cv19 is no big deal. I agree with grandsire, there will be an inevitable second wave and maybe a third which will see schools close and life return to quarantine rules. After reconsideration, I reckon schools will not reopen in 2020.
