Do other householders isolate of one has had a test

[Chaotic45]

A 19 year old I know found out his gf had received a positive test on Friday evening. He has been spending ltime with her and they slept together on Friday. I'm not clear whether he knew she was awaiting test results, I know this sounds odd but it's not my place to interrogate them, he's a good kid and I feel for him!

I had spent the evening indoors with the 19 year old and his parents on Friday night prior to him hearing about his gf's test results. We were socially distanced, we shared a takeaway but they stayed over 2m away, they used our bathroom.

The 19yo has no symptoms. He isolated immediately and got a twat on Saturday. No results yet.

I've scrubbed my house.

I'm not sure how he got a test as he's asymptomatic. He's been sensible enough to use the app- so I'm wondering if if helped him organise a test whilst being asymptomatic.

I've checked the guidelines as to if his household and my household should be isolating. But the guidelines assume he has symptoms- which he doesn't.

So am I right in thinking:
He should isolate for 14 days regardless of his result.

They don't need to isolate unless he gets a positive test, or unless app or T&T tells them to.

We don't need to isolate unless we get symptoms, or app or T&T tells us to- regardless of his test results?

I'm sorry for all the questions. I have checked the guidance but I am confused as it assumes he's got symptoms, but he hasn't.....

I want to make sure I'm doing the right thing. Despite not isolating as I don't think I have to, I am having no social contact for 2 weeks and I am able to work in a safe way. My DS is at school though.

He should be isolating for the 14 days regardless of a negative test at this point. Any people in his household should isolate for 14 days from the onset of any symptoms he develops - if he develops no symptoms they don't have to isolate (whether they still should reduce their own social contacts knowing what they know is up to them).
You don't need to isolate unless he tests positive, 14 days from your contact with him.

@jerometheturnipking thank you that's really helpful. We haven't been within 2m of him, so I'm not sure why we need to isolate?

We will if we need to of course. But can you point me towards where this is set out please?

The fact that he got a test, then family members have to isolate until he gets results.

It would come down to whether you were classified as a close contact or not at that point. Under this guidance:www.nhs.uk/conditions/coronavirus-covid-19/self-isolation-and-treatment/when-to-self-isolate-and-what-to-do/
You might be classed as a close contact as he was in your home for a prolonged period for the takeaway. But it would come down to what the contact tracers judge I guess.

In Scotland (where I am), his family would have to isolate while he's awaiting a test result. According to the page I linked, they don't have to isolate as he's got himself a test without symptoms, and the guidance there states "you live with someone who has symptoms or tested positive" (and potentially he's got himself tested before he would even develop Covid depending on whether Friday was the only time he had seen his GF that week or not).

@jerometheturnipking thank you for clarifying that's really helpful.

They are the only people we have had in our home for months. Oh how I regret it now!

I've no idea how often he's seen his gf. His family haven't been very forthcoming with details and it feels nosey to ask.

I can see that he may have tested too early. But I guess if he tests negative then that's good for my household as it means he wasn't shedding virus when in our home (false negative notwithstanding).

I'm not too sure how he can not get it TBH though- surely having sex with someone is as risky as it gets 🤷🏻‍♀️.
