Isolation help!

[Thoughtsfortheday]

We are a family of five, two DC have had positive PCR tests, on Tuesday morning (though symptoms started on the Saturday) and one on the Wednesday morning (no symptoms) we have been ad will continue to isolate as a family until 10 days of 2nd DC is up.

However 3 DC has had a positive LF test today (have been testing every day just 1st day 2nd line has come up) and I’m presuming they will also isolate for 10 day from their +PCR

Question is for we all have to reset the clock now and isolate as a family for a further 10 days or just 3rd DC?

No the clock doesn't reset for everyone, just the person with the positive test

If everyone has been self isolating since the first person had symptoms then isolation is 10 full days since that person got symptoms for anyone who has not tested positive.The clock doesn't reset whilst they are still isolating.
Anyone who has tested positive has to do 10 days from when they got symptoms or tested positive ( if asymptomatic).

If you have been self isolating since last Saturday and do not have symptoms or a positive test, you finish isolation on Tuesday night.

No your isolation ends as planned, only the person who got it recently has to isolate longer
