An ecological approach to the problem of the responsibility of men and rats in the workings of a transmission site of Schistosoma mansoni in Guadeloupe (Western Indies)

Abstract:

The study of the rate of contamination of B. glabrata and the cercarial densities of S. mansoni in the channels of Beaugendre valley (Guadeloupe, French West Indies) concentrates attention on the focalization of the sites with high risk of contamination. This focalization of the sites of transmission is directly related to the regular deposition of human faeces. A small number of contamined people is enough to maintain high cercarial densities (230 c/1). In the channel studied, the role of the rat in the transmission of the parasite seems less important than that of man. The infection of the rats during consumption of snails can be foreseen.
