Health Issues and Related Data
nIncreased waterborne diseases since the dams were constructed, including schistosomiaisis, malaria, Rift Valley Fever, river blindness nProliferation of snails, which can be an intermediate host of human and animal trematodosis
Increase in the proliferation of the snails is caused by the prevention of the intrusion of saltwater in the Senegal River, regularization of the level of the water of the river and other effluents in the delta, and the pH of the water becoming more alkaline.

First outbreak of schistosomiasis occurred in the delta town of Richard-Toll in 1988-89

After Diama dam became operational and many hydro-agricultural activities were set up, an increase in animal trematodosis was observed in the SRB as well, for example an increase in the infestation rate in cattle was observed.
