Abstract

A focus of intestinal schistosomiasis was discovered in november 1981 in Martinique in the Saint-Pierre area. An analysis of its structure and of the mecanisms of the transmission of the parasite was carried out between 1981 and 1983. This focus presents the following particularities: a transmission site very small constituted by water cress beds; a small human population infected with a prevalence of 13% (positive stools) to 41,3% (positive serologies); a weak fecal contamination of the water; a non functioning sewage stabilization tank is responsible for this contamination; a rich population of the snail host Biomphalaria glabrata (40,5 to 256,3 Bg/m2) with a low prevalence of infestation (0,13 to 0,59%); low cercarial densities in the water cress bed waters; a very low contamination of the Roxelane river water in to which the water from the water cress beds flows. The epidemiological importance of this contamination has proved very low but not altogether absent. This focus appears as a particular case in Martinique because all the surveys which have been conducted in the island to date has not uncovered a similar example.
