Should I be worried?

Our daughter is sick today, she has a fever and flu symptoms. She isn't too bad really but I am worried that I will catch whatever she has like I normally do. I have been taking lots of precautions such as earlier nights, eating well, taking antioxidants and not eating or drinking from the same bottles or plates as the kids. But the fact remains that I have increased my training in the last few weeks. My running has been going really well too. Maybe I won't get it, maybe I'm worrying over nothing or maybe I should take it easy over the next few days just in case.
