Ah! Sad you think like that OP!
I taught in a residential school when SARS hit. We had lots of foreign kids doing summer school and one of them came down with it. They were all quarantined and, because I shared a lunch room with them I was asked to volunteer to stay and help out.
Many staff did so, teachers, cleaners, canteen staff etc, a couple got SARS and were further quarantined. All got well, as did the few kids that got it too.
So no... I don't reall think that anything unusual is being asked of nurses here!
The point is not that it probably won't kill us. The point is, as others have said, to try and stop it spreading to third world countries where there isn't the infrastructure to deal with it, where people may not have such good heath.
And don't tell me it won't get there... look how quickly it got here! That isn't hysteria, I don't think it would harm me much if I did get it. It's common sense and thinking further than the end of my own nose!
