Dd tested positive last week after the mildest of symptoms. If her brother and I hadn't been ill I wouldn't have even tested her. Just a blocked nose, very occasional cough and nausea. All very mild and would have gone to school pre-covid times. She's been back at school since her isolation ended 2 days ago but now has a proper cough, sore throat and feels sick and actually feels unwell whereas she didn't before. Has anyone else or their dc experienced this?
