Beginning this week, HIV.gov is launching a new blog area focusing on the latest developments in HIV/AIDS research from the agencies of the U.S. Department of Health and Human Services. This is just one more way that we hope to use social media as a method for keeping you in tune with what's happening in the fight to end the global HIV/AIDS pandemic.

Next week, we welcome guest blogger Dr. Carl Dieffenbach, director of the Division of AIDS at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. As a leading federal research institute on HIV/AIDS, NIAID supports and conducts international and domestic research designed to better understand the virus and find new and improved HIV treatments and effective ways to prevent HIV infection. In his initial blog post, Dr. Dieffenbach will discuss NIAID’s research agenda for preventing HIV infections here in the United States of America.
