[Epidemiologic study of onchocerciasis in the Matakams of the Mandara Mountains (North Cameroon)].

The epidemiological study of onchocerciasis performed in the area, where a certain number of dams are already build, shows that the prevalence of the disease varies in the different villages. The variations observed are probably in relation with the distance separating the villages from the temporary breeding sites of S. damnosum. The onchocerciasis is of the savannah type. The visual acuity is low and blinds are frequently seen in the villages where the prevalence of the disease is high.
