One area in which there has a lot of enthusiasm in recent years is in HIV prevention. A number of significant advances have come to fruition over the last decade in prevention: microbicides, male circumcision, treatment as prevention universal testing and pre-exposure prophylaxis are a few that come to my mind.

As we head into the XIX International AIDS Conference this month in Washington, D.C., prevention is a big part of the discussion around ending the AIDS epidemic and the Washington D.C. Declaration.

Brad Hare gave me a nice run-down on the science of prevention and how it has changed in the last few years–the new biomedical methods of prevention and how they might be used in combination with the tried and true behavioral intervention of condoms, clean needles and education.
