Onchocerciasis in Benue State of Nigeria. VI. The prevalence and distribution of the disease among the human population in Sati-Ikyov village.

Following our report on onchocherciasis among the Ikyov and Nanev clans, we initiated a survey of the prevalence and distribution on onchocerciasis in some villages in Benue State, Nigeria. Out of the 1,558 inhabitants (619 males and 608 females) examined, 1,227 (78.8%) were found to carry microfilariae (mf) of Onchocerca volvulus (mean density: about 20/skin snip). The presence and number of mf from the right and left iliac crests were comparable. The findings indicate that clinical manifestations in onchocerciasis remain vital indices for rapid prospection.
