DS (10) came home from school last night complaining of a sore throat but no temperature and otherwise fine (eating, gaming etc) a few hours later his temperature was really up and he was very clearly unwell. This morning temp totally gone and looks like it's now a cold - lots of snot, taste and smell okay and eating & drinking okay. My gut feeling is he's picked up a cold from school but obviously don't want to take any chances at the moment. Also the rest of us in the house are fine.
So in the above circumstances would you be self isolating and contacting school (also my DD school)
Thanks
