Help! I’ve lost track of the rules and don’t know what to do. DD (3) tested positive for Covid on a PCR on 24th Jan. one of her symptoms was a cough which has never gone but over the past 24 hours it has got worse again and she has developed a temperature. She was sick last night too which she was when she first had Covid symptoms. Should I be doing another PCR or are you not meant to test within 90 days? So confused, could this be Covid again?
