Is an 'AIDS-free generation' really possible?
KISUMU, Kenya – Thirty years after the discovery of AIDS, scientists believe for the first time that they now have the tools to beat back the deadly virus.
The evidence is found in HIV prevention research conducted here on the shores of Lake Victoria and in several other parts of sub-Saharan Africa, long the epicenter of AIDS. The most notable research discovery stems from the HIV Prevention Trials Network 052 clinical trial, a U.S.-funded, nine-country study that found early treatment reduced the risk of HIV transmission to an uninfected partner by 96 percent.
The 052 results – announced to a standing ovation in Rome at the International AIDS Society conference in July – was one in a line of recent breakthroughs, including the benefits of male circumcision to prevent infection, and smaller conceptual advances in an HIV vaccine candidate as well as with microbicides, or gels used by women to stop transmission.
But the gloomy global economic situation, and recent scale-backs in HIV funding around the world, have cast great doubt as to whether policymakers will take advantage of the combination of new prevention tools to fight AIDS.
This collision of scientific advances vs. economic realities also comes at a heightened political moment of the U.S.’s own making: Secretary of State Hillary Rodham Clinton earlier this month called for an “AIDS-free generation,” and the United States’ actions on AIDS will be in the spotlight during next July’s International AIDS Society conference in Washington, D.C., which is being held in the U.S. for the first time in 22 years due to the Obama administration’s decision last year to end U.S. entry restrictions on people who have HIV. The conference is expected to attract more than 25,000 people from around the world.
President Obama is expected on Thursday — World AIDS Day — to talk about his administration’s next steps on AIDS, following Clinton’s speech. This would be his first major speech on AIDS as president; he has remained largely silent on all global health issues. Even when Obama announced a bold new Global Health Initiative, the White House put out only an eight-paragraph statement.
“The terrific science in the last year is coming up against the fiscal constraints,” said Chris Collins, vice president and director of public policy amfAR, the Foundation for AIDS Research. “It is going to take choices. That is the big challenge for policymakers in the next couple of years: How to get above the day-to-day politics here and use the resources as strictly as possible. We now need to hear our president articulate his policy action plan for an AIDS-free generation.”

Several sources within the Obama administration said in interviews that Clinton’s speech at the National Institutes of Health was at least partially spurred by the realization that next year’s AIDS conference will shine a spotlight on the U.S. commitment to fighting the virus, both globally and domestically. The idea was that the United States will be able to report back to the conference on its plan of action globally, while also speak about ongoing research in several U.S. cities about the most effective ways of finding those who are infected and then putting them on treatment.
In the meantime, Obama’s top scientists are urging that the research discoveries to prevent HIV transmission are put to use. The one in the forefront is the best known of all: Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, who has advised U.S. presidents since Ronald Reagan on how best to address AIDS.
“All of a sudden we have a convergence of prevention approaches, which includes treatment as prevention, and that really validates the concept of combination prevention,” Fauci told GlobalPost in an interview earlier this month. “There is now an enthusiasm and an excitement if we can implement some of these scientific advances, we can have a major impact in turning around the trajectory of the epidemic.”
