Children are back at school in Scotland. And look what has happened to the number of reported Covid cases:
The number yesterday was about double the seven-day rolling average. That increase is staggering.
Of course, this does not prove causation. But if, as seems likely, the school holidays caused the tumble in the number of cases (they start school holidays at the end of June in Scotland) then it seems very likely that schools reopening is now causing the new spike.
If that is true then we are heading for this coming winter in a very bad place when it comes to Covid. I wish it were otherwise, but the widespread assumption that Covid is over - evidenced by the unmasked crowding in the House of Commons this week - is wrong. And that is really quite scary.
