Received a text on Thursday evening from school asking my Y9 dd to SI for 14 days due to 'close contact' etc.
Lots of Whatsapping amongst the kids - some of the class asked to SI but not others.
Two of the girls not instructed to SI were off school on Friday. Neither had any symptoms, but both tested positive over the weekend.
Both have siblings in different schools. One of which I happen to know had 50 teachers and counting SI on Friday.
This is a significant part of what's driven up transmission in secondary schools in particular. The head at the '50 teachers and counting' school's plan over the summer was to send home year groups to work at home via online learning for two weeks as soon as one child was identified as positive. This was, of course, over-ridden by Dido and her Cash Cows.
That type of affirmative, proactive approach is what would have contained transmission in schools hence the community.
