Exposed to stomach virus!!!?

I am very young, but i have been exposed to a lot of stomach viruses. But i do not think you normally get stomach viruses by having a friend visit for a while. Raw foods, and extreme exposure to someone sick with it could cause it. And plus she RECOVERED from one, which only lowers your percentages, along with your amazing cleaning. I think you will be fine, but you will find out tonight when you are sleeping well, or next to the toilet all night. Also, congrats for your sister!
