Site of Schistosomiasis Transmission, Senegal River

Photo of members of a local village near the Senegal River. After a dam was built downstream of the village, river prawns that normally migrated upstream could no longer do so, and the number of snails bearing parasitic schistosomiasis increased. Consequently, villagers who relied on the river water as a major part of their lives contracted schistosomiasis and suffered from symptoms that included anemia, fever, chills, and abdominal pain.
