West African Sleeping Sickness
A form of Human African Trypanosomiasis caused by Trypanosoma brucei gambiense. It has a slow course with few symptoms in the initial phase. It is usually transmitted by a tsetse fly species of the riverine group (Glossina palpalis) in a man-fly-man cycle. While animals can also get infected with T.b. gambiense, the role such infected animals play in transmission still needs to be clarified.
