HIV Prevalence Increases in the U.S., 48% Are Black
August 14, 2006
Looking at how the HIV epidemic is affecting people in the United States is important to understanding both HIV prevention and treatment needs. The objective of this study1 was to describe the recent epidemiology of HIV infection in the 33 states of the United States that have been reporting HIV infections to the U.S. Centers for Disease Control and Prevention (CDC). This was an analysis conducted by Michael Campsmith of the CDC on HIV surveillance data from 33 states reporting confidential name-based HIV infections since 2000. Data was adjusted for reporting delays and redistribution of unknown transmission categories. Reporting included both HIV infection, AIDS, and prevalence rates per 100,000 population.
HIV risk factors for males (more than 13 years, n = 332,190) were 60% men who have sex with men (MSM), 19% injection drug use (IDU), 13% heterosexual transmission, and 7% MSM and IDU. HIV risk factors for females (n = 123,178) were 71% heterosexual transmission and 27% IDU.
Prevalence and rates by race were as follows:
The limitations of this study are that the data is limited to 33 states and reporting trends are limited to five years starting from 2000. The analysis is also missing some states with known high HIV infection prevalence, such as California, Illinois and Maryland. Finally, not all patients with HIV infection have been tested, diagnosed and reported to the CDC in the 33 reporting states, which further underestimates the prevalence.
