The International AIDS Conference is under way in Washington, D.C., this week. This is the first time the U.S. has hosted the event in 22 years. During those decades, new HIV and AIDS treatments have transformed the face of the epidemic. In 2010 alone, drugs prevented 700,000 AIDS-related deaths worldwide. Dr. Anthony Fauci, a leading HIV and AIDS researcher, is at the forefront of these breakthroughs. Fauci has led the National Institute of Allergy and Infectious Disease since 1984. Today, he says an AIDS-free generation is an attainable goal. Dr. Anthony Fauci joins Diane to talk about the challenges of HIV and AIDS, and what it will take to turn the tide.
