Abstract: | Tsetse-transmitted trypanosomiasis is an important diesease of livestock and people in large parts of Subsaharan Africa. It occurs in various epidemiological settings driven by the encroachment of people and livestock into tsetse-infected areas. Each epidemiological setting represents a particular host-vector interaction. Of particular veterinary importance is the situation where the livestock (mainly cattle) have become the main host of tsetse flies and the main reservoir of trypanosomes. This change from a sylvatic to a domestic transmission cycle seems to result in a reduction in the prevalence of highly pathogenic trypanosome strains and thus a reduction in the disease impact. The creation and maintenance of such trypanosomiasis endemic areas may constitute an additional tool in the control of the disease in livestock. Bibliogr., sum. in English, French and Dutch.
