Why Universities are Disease Factories

I got back from my trip Saturday, and planned to grade and get started on school stuff. Did not happen, as I'm feeling ill. Normal cold issues, plus a sore jaw. Normally I would just ignore it, but I'm stressed, and Tom mentioned mumps. So I go the KU health services. I don't know if I fit the symptoms, but I'm supposed to stay home if I have it. So I try to get an appointment at Watkins. No luck Sunday, as they're closed. Call this morning, and get told that they can't schedule an appointment because the system is down. I mention the suspesion.. and get my information taken and told that I'll get a call back. I ask when.. a few hours. Hmmm.. Do I go to class? Apparently. Because I've already missed a week. If I am infectious, I get to spread it around. So what happens if a real epidemic occurs?

EDIT: I may have mumps, but the best test they can do is to feel my neck. I might have mumps, so I am quarentined until Sunday. This makes schoolwork difficult.
