Continuing racial differences in HIV prevalence in US

Poverty, a reality of life for a disproportionately large number of African Americans, is strongly associated with HIV infection.

Writing in the article, Adaora A. Adimora, MD, MPH, University of North Carolina at Chapel Hill, School of Medicine, states, "Continuing racial disparities in HIV infection more than 2 decades after the identification of the virus and availability of an accurate test are an indictment of the U.S. response to the epidemic. Existing interventions have failed to control the epidemic in African Americans in part because critical features of the socioeconomic context promote behaviors that transmit HIV and increase the risk of HIV infection even among those who do not have high-risk behaviors. Failure to address these structural determinants has allowed the epidemic to continue in the black community.
