I dont think people realize that despite the advances in medical science and techonology, human kind has cured only ONE viral disease (Hepatitis) and even that not effectively. Flu, Herpes etc.. are not cureable. We only treat the symptoms and the virus can go dormant for years before they are active again. For other viral infections like small pox, mump etc, we have vaccinations, but it is upto the individual's anti body to build defense against these infection. We are still decades away from finding cure to HIV virus. This is based on my personal research into pharmacy stocks 15 or so years ago.

We have biologists, doctors on the board.. maybe they can confirm.
