School incorrectly advising isolation

[321Backintheroom]

So late last night an email to say my child needs to isolate for 14 days as someone in the class has a member of their household that’s tested positive and they have closed the whole class down .
I have tried contacting the school and because it’s half term nobody is responding to emails or picking up the phone but this isn’t the right process is it ?
The child who has a family member that’s positive needs to isolate but not the whole class ??
We were due to go on a uk break today but now we can’t go because nobody at the school can clarify the position .
So potentially 14 day isolation that’s too early because the child in the class isn’t actually positive the family member is .

Sounds wrong.

We had an email over half term about a case in a pupil just saying their close contacts have been informed and everyone else to carry on as normal and expected back next week as usual.

I have known a case where two siblings tested positive and the official letter that went to parents said that someone in a students' household had tested positive - so maybe that's the wording they use when it's more than one individual from a family?

(the siblings were both students at the same school)

Please could someone just clarify what the rules are? Re a school asking is to isolate?

Head has just ring. To say that a child in Ds2's year is positive. Ds2 is on 1/2 Term this week, so hasn't been at school since last Friday, so Head said ds2 only needed to stay off next week.

Is that correct? He's asymptomatic and feeling fine. Should I get him a test? If it's negative can he go back sooner?

No test. No he can't go back sooner.
