Let's remind ourselves of the government's own 5 tests for reopening schools safely:
First we must protect the NHS’s ability to cope, and be sure that it can continue to provide critical care and specialist treatment right across the whole of the United Kingdom.
Second, we need to see daily death rates from coronavirus coming down.
Third, we need to have reliable data that shows the rate of infection is decreasing to manageable levels.
Four, we need to be confident that testing capacity and PPE is being managed, with supply able to meet, not just today’s demand, but future demand.
And fifth, and perhaps most crucially, we need to be confident that any changes we do make will not risk a second peak of infections (that will overwhelm the NHS).
So death rates are going up, they're incredibly worried about infections spiralling out of control, testing is ballsed to fuck and they're very worried about the coming winter.
And they have backtracked on the idea that kids don't spread it that seemed to be the mainstay of arguments against any mitigation measures in schools.
But schools reopened anyway.
If you are arguing that current rises in cases are nothing to do with schools, then you must accept that the govt have reopened them at an unsafe moment according to their own tests and therefore cases will rise because of schools being open.
