Year bubble closed - can't find guidance on how this works practically?

[MsGillis]

Apologies, I've googled and searched here before posting this, but I can't find any definitive guidance.

Year 8 child has been told to isolate for 14 days after someone in their year group tested positive. That's fine, I'm glad the school are taking it seriously as I know other schools are just isolating children who were literally sat next to a child who's tested positive.

What I don't know, is whether we should all be distancing from him at home while we wait to see if he develops symptoms?

And can anyone explain to me how it's supposed to be ok to send my Year 10 child in, even though Year 8 child isn't allowed to set foot outside? If (heaven forbid) my youngest one develops symptoms and has the virus, the eldest is likely to do the same, but has then had x days at school to infect their whole year group. I know that technically that is the guidance, but can anyone explain why it is, and how it doesn't put another year group at risk?

Thanks @steppemum, that's really useful. I'm sure the school will send out something similar shortly, they'll be run ragged I guess. We got the text very very late last night, the poor teachers having to deal with that...

and to the person up thread who said they were at home as one of the family are being tested.

If you are being tested then you must have symptoms.
If you have symptoms, the whole family must self isolate.

And self isolate means no leaving the house, no shopping, no dog walking, no exercise, no school, no work etc. It is much stricter than lockdown was.

Under test and trace only your child needs to isolate

This is the link we were given. You're right, it IS different from self-isolation when it's a contact you don't live with and it is confusing. But the rest of you don't need to isolate or test unless dc shows symptoms. But they can't leave the house. www.gov.uk/government/publications/guidance-for-contacts-of-people-with-possible-or-confirmed-coronavirus-covid-19-infection-who-do-not-live-with-the-person
