Worth looking at the Italian intensive care professor interviewed by JAMA here.
We are lucky to have their warning- 14days since their first case and he feels the "surge" is still to come (that's my interpretation of what he says).
We need to go into intense lockdown now ...no pubs, Corona parties, trips to the beach, "running into" friends on local walks etc.
Lots of teens out today (according to my DC) meeting up at the local indoor slots/bowling areas.

"Flatten the curve" (ref John Campbell).... slow down the rate of transmission, so that those of us who get it, or whose parents get it, will have a hospital bed to go to.
to all our nurses, doctors, ambulance personnel, admin support who will be putting themselves on the line.
And to answer your question OP, I can't see schools reopening. We will see our surge coming in the next 4-8weeks (all those Cheltenham returners will be shedding for the next 2 weeks, then all their contacts and so on).
Please God, NI gets agreement to coordinate their response with the RoI.
