What has happened over the years is that scientists have now developed AIDS therapeutic capabilities, as well as prevention, and we've linked prevention and treatment in a way that if you fast-forward 30 years form '88 to now, we can say without hyperbole that we have the tools, if implemented the way they could be implemented, to theoretically, essentially end the epidemic as we know it now.

Better ways to diagnose, treat and prevent E. coli 0157:H7 infections are badly needed.

We can sharply deflect the curve of HIV incidence.

Previous efforts to eradicate malaria failed for several reasons, including political instability and technical challenges in delivering resources, especially in certain countries in Africa.

You help someone's health, and you prevent them from infecting others.

When you put someone on therapy, you lower the level of virus such that it makes it very difficult for them to infect others.

Although it is still important to develop an HIV vaccine, we have significant tools already at our disposal that can make a major impact on the trajectory of this epidemic.
