School bubble closed - isolation period question

[BeingATwatItsABingThing]

Sorry if the back story is confusing. I’ve tried googling but can’t find a definitive answer. I’m hoping someone more knowledgeable on MN will be able to help.

DD1’s year group bubble was told to isolate for 10 days after a positive covid case. The child’s last day was the Thursday so the isolation period ends today and she’s allowed back into society again tomorrow. Woohoo!!

However, one of the parents has asymptomatically tested positive in the last couple of days. They haven’t been anywhere since school (I know the family and this is definitely true. Her health condition means that she’s taking covid very seriously) so it’s most likely she caught it from her DD. Her DD was in school on Friday so does this mean we have to isolate another day?

All of our half term plans had to be cancelled due to this and, as DD1’s school has a training day tomorrow, we were going to do something nice together as a family. We’d like to be able to do that but will obviously follow isolation guidelines.

I think it's only contacts within 48 hours of symptoms or positive test so if her daughter didn't test positive/ show symptoms until Monday then she won't have any contacts outside the household?
Are the kids doing tests as close contacts? (I'm in ni - recently they introduced that all close contacts are to get tests)

Honestly I'm not 100% sure though but I don't think you have to increase your isolation period if someone outside your household tests positive during the isolation period as they should have been isolating before able to spread it?

You don't know where they caught it. You only need to isolate for close contacts. Unless your daughter was a close contact of this parent in the two days before the test then she doesn't need to self-isolate. Yes, their daughter could have been positive, but they didn't test her so they don't know that. We can't start back-tracing close contacts of potential cases or we'd never be allowed out!

There is no requirement to isolate in this situation because the daughter hasn't tested positive and she is your daughters potential contact not the mother.

Also if a class has to self isolate and others in the class test positive during that self isolation period, the clock doesn't restart for everyone else.

No your fine. There's nothing to suggest the daughter had covid Friday, so it ends today

Amazing! These were the answers I was hoping for. Thank you.
