    AIDS. 1997 Dec; 11(15):1867-72.

    To assess the impact of the 1994 expanded World Health Organization (WHO) AIDS case definition upon AIDS surveillance in Cote d'Ivoire, passive AIDS case surveillance was conducted from March 1994 through December 1996 at the 3 university hospitals in Abidjan, while active AIDS case surveillance was conducted at the 8 large tuberculosis (TB) centers throughout Cote d'Ivoire. Standardized questionnaires were administered and blood samples for HIV testing were collected from patients evaluated. 3658 of the 8648 hospital patients met the clinical and/or expanded case definition: 744 HIV-seropositive individuals met only the expanded definition, 44 HIV-seropositive individuals met only the clinical definition, 2334 HIV-seropositive individuals met both definitions, and 536 HIV-seronegative persons met only the clinical definition. Of 18,661 TB center patients, 9664 met the clinical and/or expanded case definition: 5685 HIV-seropositive individuals met only the expanded definition, none of the HIV-seropositive individuals met only the clinical definition, 2625 HIV-seropositive individuals met both definitions, and 1354 HIV-seronegative persons met only the clinical definition. The use of the 1994 expanded definition for surveillance purposes should be encouraged in areas of the developing world where HIV serologic testing is available.
