FOR IMMEDIATE RELEASE
Tuesday, Nov. 3, 2009
Approximately 2.7 million people were infected with HIV worldwide in 2007—an average of more than 7,000 individuals each day. In the United States, nearly 600,000 people have died of HIV/AIDS, and an estimated 1.1 million people currently are living with HIV infection. Each year for about the past 15 years, approximately 56,000 people in the United States have become newly infected with HIV.
In a new article in Health Affairs, Anthony S. Fauci, M.D. and Gregory K. Folkers, M.S., M.P.H., discuss the urgent imperative both to scale up proven tools of HIV treatment and prevention, and to develop bold new interventions—from curative therapies to vaccines and other new prevention modalities. Dr. Fauci is director of the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health. Mr. Folkers is health scientist and chief of staff in the Immediate Office of the Director, NIAID.
The authors note that only a fraction of people who need HIV treatment, prevention and related services is receiving them. Even if access to scientifically proven HIV services were greatly improved by increased funding or improved efficiencies, slowing and ultimately ending the HIV/AIDS pandemic also will likely require major advances in two areas. First, curing a sizable proportion of those already infected with the virus such that lifelong therapy is not required; and, second, developing more powerful prevention tools to slow the rate of new infections. The authors assert that the scientific challenges related to these two goals are the most important issues in HIV/AIDS research today.
The authors explain that a cure theoretically could involve complete eradication of HIV from the body, a “sterilizing cure.” Alternatively, a cure could shrink the amount of HIV in a person’s body to the point where the immune system could control the infection without antiretroviral drugs: a “functional cure.”
Other compelling challenges in HIV/AIDS research relate to developing, assessing and validating new approaches to blocking HIV transmission. These approaches include:
The authors conclude that it is essential to sustain a robust HIV/AIDS research agenda to develop these interventions, which have the potential to be truly transforming. Without such tools, the scope and burden of the HIV pandemic will continue to grow.

NIAID conducts and supports research—at NIH, throughout the United States, and worldwide—to study the causes of
infectious and immune-mediated diseases, and to develop better means of preventing, diagnosing and treating these illnesses. News
releases, fact sheets and other NIAID-related materials are available on the NIAID Web site at www.niaid.nih.gov.
About the National Institutes of Health (NIH): NIH, the nation's medical research agency, includes 27 Institutes and Centers and is a component of the U.S.
Department of Health and Human Services. NIH is the primary federal agency conducting and supporting basic, clinical, and translational medical research,
and is investigating the causes, treatments, and cures for both common and rare diseases. For more information about NIH and its programs, visit www.nih.gov.
