Risk behaviors in volunteer blood donors who seroconverted for HIV, Abidjan, Côte d'Ivoire 1997 to 2005.: HIV infection risk factors in seroconverted blood donors in Abidjan

Abstract : BACKGROUND: The residual risk of human immunodeficiency virus (HIV) transmission from blood products in the Abidjan National Blood Transfusion Center was estimated to be 1 in 5780 blood donations over the period 2002 through 2004. We aimed at describing risk behaviors in blood donors who seroconverted for HIV in Abidjan to improve the pre-blood donation selection. STUDY DESIGN AND METHODS: We investigated the behavioral profile of HIV seroconverters assessed before their HIV diagnosis, during the blood donation selection at the blood bank of Abidjan, and compared it to the profile documented after this HIV diagnosis, at enrollment in the PRIMO-CI cohort. Since 1997, enrollment in this cohort is offered to every blood donor whose delay since HIV seroconversion was 36 months or less. RESULTS: Among the 418 blood donors who seroconverted for HIV between 1997 and 2005, 241 were enrolled in the cohort. Median age was 28 years and 63% were men. The median time between the last HIV-negative test and the first positive test was 7 months. Since the last blood donation, 29% of donors reported unprotected sexual intercourse with multiple casual sexual partners, 55% unprotected sexual intercourse with one casual sexual partner, and 36% sharing of nail clippers. During the pre-blood donation questionnaire, 69% of HIV seroconverters had reported unprotected sexual intercourse since the last blood donation (vs. 89% reported after donation), and 7% had had multiple casual sexual partners (vs. 32%). CONCLUSION: Volunteer blood donors who seroconverted for HIV in Abidjan reported a high proportion of unprotected sexual intercourse with casual sexual partners.
