DS1 had a positive covid PCR result yesterday. He has been isolating since last Sunday due to two friends he was with last weekends testing positive on LFTs on Sunday and later confirmed positive on PCRs on Monday. So DS has had no contact with anyone except me and DS2 since last Sunday. He took a PCR that was negative on Wednesday however he developed symptoms later on Wednesday so decided to test again yesterday and it was positive.
I have ordered PCR tests for myself and DS2. According to the guidelines we have to test on day 2 and 8 since last contact with the positive case. But we live with him. He has been isolating as much as possible in his room but our paths have crossed. So when is day 2 and day 8?
