i just had an experience with a very similar situation. My friend and i were at a party together and her kids were there. The next day she called and said that her baby had V'd. Total he did it 4 or 5 times no D though. The next day her older boy was sick. He only V'd twice. i kept waiting for her to get it and she didnt. She even slept with the baby when he was sick and he V'd in her bed. Of course she was the one cleaning up after them too. I thought for sure. But she didnt. She has been fine. This past Saturday made a week since her first kid V'd. I figured she would have gotten it by now if she was going to. If your co-worker did catch it from her kid it doesnt mean that you will catch it from her. Dont use the bathroom where she just went. Try not to answer phones that she did or touch stuff that she did. Keep your hands clean. Good lucK!!!
