Hi, apologies if this is a silly question, but I'm a bit confused. My DS tested positive for Covid very late on Tuesday night, was borderline Wednesday morning. I'm taking Wednesday as day 1 as advised by his school. I understand that he needs to do lateral flow tests on days 6 and 7 (which will be Monday and Tuesday) and that he can return to school if these are negative. Does this mean he can go back to school on day 7 (Tuesday) if he's negative, obviously if he does his test first thing. Thanks
