I went to a large greek school in the days before we were all nuts about hand sanitizer.
I had mono the summer before my RUSH followed by a type of walking pneumonia. The doc said that I was prone to this because of the mono.
By the time I hit RUSH, as we called it, I was on antibiotics for the walking pneumonia. Aside from telling my RUSH roomie, we had separate RUSH housing for early RUSH, no one really knew. I made sure that I was in bed at 9pm every night. Also, my mom had driven down with me and stayed at a hotel so she made sure that I got fed and relaxed.
The bad thing was that I did not probably socialize as much as I could have and made friends during RUSH. But, I had all of my college time to make up for that!
The good thing was that I did not hear all of the tent talk. Between seeing mom at the end of the day and getting to bed, I did not have much time.
And, no, I DID NOT TELL GREEK LIFE. I knew that I would be fine. Again, rest was the key. Worst case scenario is you tell Greek Life a week or less ahead.
I would play it by ear, getting plenty of rest and a liquids. See how things go. Plus, recruitment can be an adrenaline rush anyways.
I really think that she will okay. I hope she is.
Oh, and suck on tons of butterscotch candies for the nasty sore throat that she has. Whole Foods has some nice spray hand sanitizer that is the size of a small travel sized hair spray bottle. Burts Bees makes a similar too.
I hope she gets better soon!!! Let us know how it goes!
