I'm thinking we don't need to isolate

[CovidConfusionSendingMeCrazy]

I'd appreciate peoples thinking here.

I must say, I am a real rule follower by nature and will absolutely SI if we need to. However this is a complicated situation and I'm genuinely confused.

So my niece's mum is in a support bubble (as allowed as a single parent) with her sister. My sibling is in a support bubble with us, though doesn't live with us. DN is therefore in both bubbles, as permitted, as she's under 18 and both parents single parents.

What I’m trying to work out is if WE need to isolate.

DN last saw their aunt on the 27th, which was 4 days before she started displaying symptoms.

Our own kids saw DN on the 29th. We haven't seen them since.

The sister of my niece's mum started showing Covid symptoms on New Years Eve and tested positive today.

DN (and my sibling and parents) are now SI as they've seen her aunt since and within 2 days of her symptoms starting.

So basically, DN last saw her aunt 4 days before she started showing symptoms, and we saw DN 2 days after that) and two days before her aunt showed any symptoms) and not since.

Would you agree? Fully prepared to be told I'm wrong - it's genuinely bending my brain! We will do what's right of course.

I could be wrong, but I think as it's contact of a contact, dn should isolate, but you shouldn't, unless she shows symptoms.

Could you call 119 for advice?

Your DN will need to isolate as a close contact just in case. If she shows symptoms then your family will need to isolate, depending how long it will have been between you last seeing her and her starting symptoms.
It’s no different to a school bubble closing due to a case in class. The whole class needs to isolate, but families of those classmates won’t need to.

Going by the logic used in schools you dont need to isolate. In schools, if a pupil is in contact with a positive case then they need to isolate but not the pupils family.

If your DN hasn’t displayed any symptoms yet and it’s been more than 2 days since you saw her, you don’t need to isolate.

Self isolation is only for people who have been within 2m for 15 minutes or longer, in the 48 hours before symptoms appear. Not for contacts of contacts.

Fab thanks all, that's my thinking but want to do the right thing so wanted to check.

None of us, including DN, have been in contact with the positive person for at least 48 hours prior to their onset of symptoms.

It was the fact we are 'bubbled' that made me check myself... but think we are ok.

No, because none of you have been in contact within 48 hours of someone who is positive. Your DN saw her aunt before her contagious period so she wouldn’t be incubating when she saw your children. Rightly or wrongly, it’s contact within 48 hours of someone starting symptoms which is the trigger for self isolation.

someone in your support bubble has symptoms and you’ve been in close contact with them since their symptoms started or during the 48 hours before they started

So, if I am reading correctly- your niece doesn't have symptoms? Niece and family isolate, you are fine. I think. You would need to isolate if your sister or niece showed any symptoms.

@HibernatingTill2030 - correct.
