This also happened to a friend with DC at a different school.
Message to parents last night, DD's class bubble will now be closed and children to isolate for 14 days as a child in the bubble has tested positive over the weekend.
Class group chat starts, one mum comes on & says it's X but we're ok. Then says X doesn't have any symptoms, was me on Friday afternoon and husband Saturday but we got her tested anyway and it's positive.
Now every single thing I have read says only to have a test if you develop symptoms. X would have to self isolate anyway due to the parents having positive tests but by getting her tested they now closed the bubble and all 30 kids are at home for 14 days. This what would happen if following the rules but then it shows the system if flawed as this child obviously did have it and was asymptotic.
So I don't know if I'm right to be annoyed by this or not. I'm certainly not looking forward to 2 weeks home schooling again.
