With advances in medicine, technology, DNA, etc this last 100 years you will probably see a medical cure in our lifetime. The medical community are 3-5 years away from releasing a herpes vaccine that prevents women from getting the virus...doesn't help people already infected though. They are trying to get it to work for men but with half the population vaccinated there should be a significant drop in new cases. It was tested in trial runs in most states.
If the medical community can do that I'm sure we are not too far off from a real medical cure. Right now tons of government funding worldwide is going into viral studies (with that deadly avain flu virus haunting us and all).
