East African trypanosomiasis
the usually acute, more severe, often fatal form of African trypanosomiasis, occurring in East Africa, caused by Trypanosoma brucei rhodesiense, transmitted by the bites of infected tsetse flies, chiefly Glossina pallidipes, G. morsitans, and G. swynnertoni. This form differs from West African trypanosomiasis in that the acute form has a duration of 3 to 9 months and central nervous system involvement occurs earlier in its course. Called also Rhodesian t. and rhodesiense t.
