Evidence for Population Level Declines in Adult HIV Prevalence in Kenya
Cheluget, B., Baltazar, G., Orege, P., et al. Sexually Transmitted Infections (2006), 82(S1), pp. i21–i26.
National survey data show that HIV prevalence in Kenya peaked at about 10 percent in the late 1990s and declined to 7 percent by 2003. Age at first sex and use of condoms increased while the percentage of adults with multiple partners fell. Gonorrhea, chlamydia, and syphilis all declined in young women attending an antenatal clinic in Nairobi. The researchers concluded that HIV prevalence decreased in some but not all areas of Kenya and that some of the decline was due in part to high levels of AIDS deaths. Prior to 2000, there were more new infections than deaths—a situation that reversed after 2000. Prevention interventions increased after 2000, too late, say the authors, to explain the earlier decline in HIV prevalence.
