Abstract
Examination of 2,876 persons in fourteen communities was carried out for clinical onchocerciasis in the Taraba river valley, Nigeria, where parasitological findings indicate unusually high endemicity. Forty-five percent of the population had at least one type of skin lesion or the other, the commonest of which was pruritus. Thirty-two percent had nodules.
Some of the nodules were located in unusual sites such as the mammae, anus. Nodule carriage and nodule-load as well as lymphatic enlargement were higher than those recorded elsewhere in Nigeria and tended to increase with increase in age.
