Last year, the U.S. Centers for Disease Control and Prevention (CDC) announced that the number of annual new HIV infections in the United States is actually 40% higher than previously estimated. This means that more than 56,000 Americans are infected with HIV every year despite public education efforts on how to avoid getting infected. Addressing the global HIV/AIDS pandemic is critical, but it’s clear that we need to re-examine our approaches and figure out additional ways to control and curtail the epidemic here in the United States.

At the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, we stand at the forefront of the nation’s HIV prevention research efforts. One of our goals is to develop new scientific strategies to prevent HIV transmission. We've had our share of successes and disappointments, like all areas of science, but we remain optimistic and are committed to ending the HIV/AIDS epidemic.
