Read the last line of this (seemingly) official @educationgovuk doc:
"YOU DO NOT NEED TO TELL OTHER PUPILS AND PARENTS THAT A CHILD HAS BEEN SENT HOME WITH COVID19 SYMPTOMS"

If this is confirmed,UK #school managements have received an official licence to lie.

jtbc:
1) I'm still not sure whether this doc is genuine;
2) I find it worrying because it encourages #school staff&management to be reticent about the actual situation.
But I'm NOT implying that this NECESSARILY shows that schools are being allowed to lie about CONFIRMED cases.

So (thanks to @Tigress58774042 !), we know know that the document is genuine; here's the source (see link):

I still find it worrying, though (see point 2 of my previous post in this thread).
