DS (15) tested positive a month ago. He isolated in his room, both DH and I are double jabbed. DS ended isolation and a week later I test positive. I'm in my last few days of isolation (stuck in my room so DH doesn't get it).
Is it possible that I caught it from DS even though it had been a week since his isolation ended that I tested positive? Or am I more likely to have picked it up elsewhere (eg work)?
