If I was in charge, I think I'd be taking quite a pragmatic approach.
Christmas is 11 weeks away.
If they put in a firebreak over the schools midterm at end of October/early November, that might get numbers down so that they can release the pressure heading into early December and Christmas.
It would be very very difficult to ask people to be locked down over Christmas; but if numbers went back up, January could be another fire break.
I suspect, they have fingers and toes crossed to keep numbers down for the next 3 weeks, though tonights numbers are v v concerning.
