This is 4 th viral infection my dd has had this year! First was covid negative. A couple of weeks later similar symptoms and covid positive (in September). Had another cold shortly after but didn’t test but negative LFT and decided highly unlikely to be covid. Now yesterday sent home from school with cough, no temperature but says feels like she has a lump in her throat. Sore feet also but fine in herself. Could this now be omicron? She had a negative lateral flow but I have mum’s funeral next Thursday and dad needs help with stuff but don’t want to pass anything on as he is being tested for pancreatic cancer?
