The way I read this is as follows
You catch Covid - and isolate for 10 days.
So does everybody else you live with and who doesn't have Covid.
On say day 4 someone else in the household tests positive for Covid, so they, you and everyone else in the household starts from scratch again and isolate for 10 days from when the second person caught it.
Fwiw I have read cases where you can catch Covid whilst you are already have Covid (if that makes sense) -
"It is possible to catch two Covid variants at the same time, experts are warning after seeing a double infection in a 90-year-old woman who became sick with the Alpha and Beta types first identified in the UK and South Africa.
The woman, who died in March 2021 in Belgium, had not been vaccinated.
Her doctors suspect she contracted the infections from two different people".
I guess the chances of that happening to most people is very remote as the Indian/Delta variant is dominant in this country at the moment but I guess in theory anyway that you could catch Covid and isolate, then on your 10th day take a test and be shown to be negative, yet the next day (your 11th and the other persons 7th) catch it again from them who still are positive from it.
I reckon that if you (assuming you are the person to catch it first) aren't going to be around the old and vulnerable and your test shows you to be negative then the chances are you are not going to be spreading it but I would continue to take frequent tests every time you plan to go out, until all the family all showing negative tests.
But why even do that and just continue to isolate for the extra few days - it isn't as though a few extra days is really such a chore is it?
Remember that even if you decide you've done your ten days and are off, all the rest of the people you live with still have to isolate for 10 days from the second person testing positive.
That's how I view things anyway but what you decide to do is up to you.
Obviously I wish that you and your family (or whoever the people are) all get through this safely.
