Aww, suze, I'm sorry ... that sux! You're right, you cannot catch anything from your neighbor simply from talking to her. Her kids aren't home so yours won't be over there and exposed so you will be fine. It could be an sv or even food poisoning or soemthing. Either way you're going to be OK.
As for the kid at school ... ewww ... but if it makes you feel better when I was a kid it seemed every year at least on kid v* in the classroom and I never caught anything from them.
I know it's nerve wracking but you're doing very good hanging in there!
