Sorry I'm a bit confused about isolation rules.
Ds1 had to vacate his Uni house last sunday. He developed covid symptoms when he had half an hour to leave the house, so we had to let him come home, he went straight into isolation. So we had no contact with him prior but of course he is having to use family bathroom. When he returned to had 2 negative LF tests and on monday had a PCR test and results negative on wed. He continued to isolate as people he had socialised with the day he left his Uni town tested positive. He had a further pcr test on friday and it has come back positive today. So clearly he must have contracted covid over a week ago as he could not have since picked it up since.
Do we now all have to isolate for ten days from now or for another 3 days. We have not been isolating since the first test came back negative on wednesday as obviously we thought he was negative and his symptoms had largely gone. Have we done anything wrong and how long do we need to isolate for now ? Any help appreciated.
