OBJECTIVES: To estimate HIV incidence from first-time testers among voluntary counseling and testing (VCT) clients in Uganda. METHODS: Data on 203,000 VCT clients tested from 1992 through 2003 were adjusted for temporal changes in the testing population. Differential mortality rates by HIV status were used to derive expected prevalence at future times from baseline prevalence within 5-year birth cohorts. Incidence was computed as the proportion of HIV-uninfected persons who seroconverted divided by the proportion negative at baseline. RESULTS: Annual HIV incidence per 100 uninfected persons increased from 0.9 (95% confidence interval [CI]: 0.8 to 1.1) in 1993 to 2.3 (95% CI: 2.2 to 2.5) in 2003 (chi test for trend, P < 0.001). Prevalence decreased from 23% to 13% in 1999 to 2000 and increased to 15% in 2003. Women had a higher incidence. Peak incidence shifted to older age groups over time. CONCLUSIONS: Estimating incidence from routine data presents a practical way of tracking HIV incidence and is a useful tool in targeting and evaluating the impact of prevention programs. Our analysis reveals a new phase of the HIV epidemic in Uganda: decreasing prevalence and increasing incidence, especially among middle-aged persons. These findings support the need for intensified prevention interventions among middle-aged persons in Uganda.
BACKGROUND: Information about the characteristics of persons whose HIV diagnosis was made soon after infection contributes to a better understanding of the HIV epidemic and to appropriate targeting of care and prevention efforts. METHODS: In 10 US cities from 1997 through 2001, specimens from consenting persons for whom a diagnosis of HIV was made within the past 12 months in were tested using the serologic testing algorithm for recent HIV seroconversion. The characteristics of those whose HIV diagnosis occurred within 170 days (on average) from seroconversion were identified. RESULTS: For 191 (20%) of the 964 participants, an HIV diagnosis was made during the period of recent infection. These diagnoses of recent infection were made more frequently among men (21.7%), whites (29.3%), men who have sex with men (25.5%), persons with a known HIV-infected partner (24.9%), and persons with a diagnosis of gonorrhea made in the 12 months before interview (27.0%). Recent infection was diagnosed less frequently among African Americans (15.5%), Latinos (15.5), and heterosexual men (14.7%) and women (14.4%). CONCLUSIONS: To increase early diagnosis of HIV, HIV testing should be more routinely offered to persons with a recent history of sexually transmitted diseases and to African Americans and Latinos in a variety of settings.
Health workers (N=692) in five Zambian hospitals were interviewed to assess HIV/AIDS risk-taking and status awareness. They comprised of physicians, nurses, clinical officers and paramedics. Only 33% had been tested for HIV and only 24% said their partner had been tested. 26 percent of sexually active respondents had multiple partners; thirty-seven percent of these had not used condoms. Only 60% of respondents believed condoms were effective in preventing HIV. Women were less likely to trust or use condoms even in high-risk relationships. The data suggest a need to develop HIV/AIDS programs for health workers, with emphasis towards gender-based obstacles hampering safer behaviors.
