[Parasitic risks (bilharziosis and intestinal parasitosis) to Mboune's valley revitalisation (Senegal)]. / Risques parasitaires (schistosomose urinaire et parasitoses entériques) liés a la revitalisation de la vallée fossile de Mboune (Sénégal).

In order to assess the parasitic risks related to M'Boune's valley water launching, a study has been carried out from September 16 to November 24, 1998 in 12 villages: four villages surrounding the Guiers lake, four villages surrounding Ferlo already water launched 10 years ago, and four villages within M'Boune not water launched. The prevalence rate of urinary bilharziosis is 0.002% in the frist area, 1.3% in the second one and 13.7% in the third area. In these areas, intestinal parasitosis are prevaling respectively at rates of 38.2%, 36.4% and 21.3%. Although, there is no reason to fear immediately a worsening of the epidemiological situation due to M'Boune's valley revitalisation project, nevertheless, appropriate steps should be taken right now aiming at tackling the extension of conditions related to hydric medium.
