Does anyone have a clear understanding of the need to self isolate? DS17 has a close friend at school that has tested positive. They are in classes together (sports class so no masks and in close contact), have lunch together etc. DS has not been contacted by track and trace or school. The guidance now looks like that doesn't mean he has to isolate, it mentions sharing households I think. They haven't had sleepovers or anything. He has taken a pcr because he has been in contact with a few positive cases and we are supposed to be seeing grandparents. Pcr results not back. Can anyone shed light on whether he should be at school tomorrow given he is waiting for a (voluntary) pcr?
