Epidemiology of HIV infection in central Brazil: Data from voluntary counseling and testing centers

Voluntary counseling and testing (VCT) is recommended to facilitate early identification of HIV infection. Data from VCT centers in Goiás and Federal District, Central Brazil, evaluated HIV prevalence and identified risk factors for HIV among individuals ages 13 years and older. Results indicated a 1.5% overall prevalence of HIV. Factors independently associated with HIV infection were: getting tested in a large city, being illiterate, having had a previous HIV test, living with an HIV-infected sexual partner, and being a noninjection illicit drug user. Being referred by friends was strongly associated with HIV infection. For men, being a health care worker, sex worker, man who has sex with men, or injection drug user were significant. In Central Brazil, HIV remains concentrated in males and subpopulations with known risk behaviors. Higher prevalence among individuals referred to VCT by friends highlights the importance of social network-based HIV prevention interventions in Brazil. © 2013 Association of Nurses in AIDS Care.
