New Facebook application idea:
Allow users to indicate whether they are ill or not. Give them the ability to list symptoms and submit a diagnosis if they have one from a doctor.
The application could then provide healthcare providers with abstracted data about disease movement. It could also warn you not to go to a concert because there is a 30 percent chance you'd get the mumps based on current confirmed attendance.

Interesting idea.
Not exactly the same, but "Who is Sick?" is a Google Maps mashup allowing sick people to submit their location and symptoms.
