I think you will be fine too. Even, worse case scenerio, say it's a sv, say he caught it from your son, you havent' caught it from your son. He was right up there next to him, probably wasn't as careful as you are and was probably worn down. That's another thing, being stressed/exhausted can make one feel sick even cause the runs so it most likely isnt' contagious but even if it is your chance of getting it is so slim. Just keep remindign yourself what the nurse said and remind yourself she IS a nurse, she has no reason to make things up to make you feel better and she knows her field. I hope both you and your hubby feel better soon!
