Trends in HIV/AIDS diagnoses--33 states, 2001-2004.

In 2003, more than 1 million persons in the United States were estimated to be living with human immunodeficiency virus (HIV) infection. As a result of advances in treatment with highly active antiretroviral therapy (HAART) since 1996, persons infected with HIV are living longer than before and progression to acquired immunodeficiency syndrome (AIDS) has decreased. Consequently, AIDS surveillance no longer provides accurate population-based monitoring of the current HIV epidemic. Therefore, CDC recommends that all states and territories adopt confidential, name-based surveillance systems to report HIV infection. This report describes the characteristics of persons for whom HIV infection was diagnosed during 2001-2004 and reported to 33 state and local health departments with name-based HIV reporting. The findings indicate that the rate of HIV diagnosis in these states decreased among non-Hispanic blacks from 2001 to 2004; however, the rate of HIV diagnosis among blacks remained disproportionately high. In 2004, the rate among blacks was 8.4 times higher than among whites. Improved knowledge of HIV status and access to care and prevention services is important to decrease the number of new HIV infections among those populations most affected.
