Racial/ethnic disparities in diagnoses of HIV/AIDS--33 states, 2001-2005.

During 2001-2004, blacks accounted for 51% of newly diagnosed human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) infections in the United States. This report updates HIV/AIDS diagnoses during 2001-2005 among black adults and adolescents and other racial/ethnic populations reported to CDC through June 2006 by 33 states that had used confidential, name-based reporting of HIV and AIDS cases since at least 2001. Of the estimated 184,991 adult and adolescent HIV infections diagnosed during 2001-2005, more (51%) occurred among blacks than among all other racial/ethnic populations combined. Most (62%) new HIV/AIDS diagnoses were among persons aged 25-44 years; in this age group, blacks accounted for 48% of new HIV/AIDS diagnoses. New interventions and mobilization of the broader community are needed to reduce the disproportionate impact of HIV/AIDS on blacks in the United States.
