[Endemic parasitoses in the villages surrounding the Saloum fossil valley, Senegal].

In order to determine the prevalence rates of malaria, urinary schistosomiasis and intestinal parasitosis in Saloum's valley, the authors carried out a study which took place from november 16 to november 24, 1996. For malaria, the global parasites index was 22% (146/662). Malaria prevails at a hypoendemic level in N'Diobène and N'Guent-paté villages and at a medium-endemic level in Ribo-Escale and N'Dodj. The infestation index for urinary schistosomiasis was 8.9% (137/154) About intestinal parasite, among 868 persons screened, 124 showed one or several parasites, that is an infestation index of 14.3%. Appropriate steps should be taken to prevent an extension of these conditions along the fossil Saloum's valley.
