I've had an alert on the Covid 19 app telling me to isolate for 6 days. It doesn't tell me where I was supposed to have come in contact with a positive person. On the day I went out and checked in to anywhere I went to hospital and also to a restaurant with my family. If it's the hospital, then I went alone, but would suppose that there were many positive people in there? And if it's the restaurant then we all should isolate, but only I checked in on behalf of us all? I'm a bit confused
