A parasitic disease of cattle and other livestock, known in Africa as nagana, caused by Trypanosoma protozoa transmitted by tsetse flies, that produces fever, anemia and progressive wasting, often fatal if untreated. It renders vast areas of sub-Saharan Africa unsuitable for cattle keeping, and its long standing exclusion of livestock and the plow from the tsetse belt is considered one of the most significant historical influences on African agricultural development.
