Trying to work out what to do with my year 11 ds as hes in the middle of GCSE's. My husband and dd have just tested positive today. My son had a very bad headache and felt sick earlier in the week but no other symptoms. Tested negative on lft but never sure if he does them right. I know he looked very unwell. Husband has more cold like symptoms and dd2 just temperature and sore throat. Wondeirng if we should isolate him from them, let him catch it with it being half term rather than it being caught by me and passed to him next week or assume he caught it first and the headache was covid-just not sure if its likely that would be his only symptom....
