didn't read the full thread yet, but one thing popped into my mind.
Could it be that it's just a PR stunt? Mass testing in secondary schools as they need to stop the transmission. > by the time they find anything* the schools will have shut anyway for xmas > sec.school age infections will go down (you know: schools are off for xmas) --> the gov will pat itself on the back about how well they handled it. And many will fall for this (hook, line and sinker)
I might be just cynical.
*think of the timeline:
dec 10 - MH says things on telly
dec 11 - orders start flowing down the command chain, logistics start, but it's friday
dec 12-13 - weekend, when the high level stakeholders are not working
dec 14-15 - ppl scramble to get it organized
dec 15 - they really start en mass to test - but they have
dec 17(ish) results start to come back AND schools break up
result: ok, tested a lot. BUT given how HTs are responsible for TTR (because of having the seating plans?!) the actual result will be that HTs and teams will be working almost up until xmas on this.
And by the time everyone is actually followed up: "free for all where nothing matters" starts up.
So apart from getting data what is the point?
(and I'm all fro data, but this seems to be a waste of money in this form)
