When my children or myself came down with vomiting bug last winter we keep away from things for 48 hours....
However, my DD vomited during a car journey the other day. It was hot, she was using her iPad and the road was windy. After clearing up and a brief 30m rest before continuing our journey, she was completely fine afterwards. I judged she’d been sick due to travelling and not a virus. I didn’t ‘quarantine’ her afterwards as a result. I think I was being entirely reasonable... but would be interested to know what others think.
