Decrease of human immunodeficiency virus prevalence in antenatal clinics in Abidjan, Côte d'Ivoire, 1995–2002.

Antenatal HIV seroprevalence surveys are important tools to understand the extent of the HIV epidemic in Africa. The main objective is to describe HIV prevalence trends from 1995–2002 in pregnant women consulting antenatal clinics in Abidjan, Côte d'Ivoire. We proposed HIV test to pregnant women consulting antenatal clinics in Abidjan from 1995–2002 in a programme of prevention of mother-to-child transmission of HIV. Yearly prevalence was estimated. Overall, 36,442 women were tested. Prevalence decreased from 14–15% in 1995–96 to 11% in 2002. The prevalence among 18–22-year-old women dropped from 15% in 1995 to 8% in 2002, while for older women it increased slightly, or remained stable from 1995–1999 and decreased thereafter. HIV prevalence among women consulting antenatal clinics has been decreasing overall. This is the first such report among pregnant women in Abidjan, probably the result of different phenomena: ageing of the epidemic and behaviour changes (disease awareness and prevention campaigns).
