I don't think we keep sending whole year groups home at secondary monkey. That's really rare and usually means a lot of (connected) cases. We have had two cases now and about 30 kids were sent home. It still isn't ideal. Some schools were doing trials of only sending home the case and doing 7 days of testing for contacts (I wonder how many comply and how accurate the LFT outcomes are) . It is ethically quite unpopular because of consent issues and government is being coy about how it is going . That said- she says cynically- I am sure the results of the trial will be what they want! With case numbers low in many areas I doubt they are learning much.
I suspect they will stick to June 21st whatever ( as seems to be the way) and, at that point, announce no more SI for contacts. But for me, as a teacher, to be comfortable with that it would have to extend beyond schools, otherwise it feels like we are always the guinea pigs : cf schools losing masks this month when nowhere else did!
My views are coloured by the Indian Variant : 50 cases in one local school (including a teacher in hospital), about 15 now in DS's.
I feel a bit bleak about it all. Rock and hard place.
Masks back from Monday at my school. Head must be so annoyed. He is a borderline covid denier and has never been seen in a mask!
