Abstract

TO THE EDITOR: The past 2 decades have heralded notable success in efforts to control sleeping sickness (human African trypanosomiasis [HAT]) in Africa. HAT is a neglected tropical disease with major public health and economic effects in sub-Saharan Africa, and its effects on livestock productivity and development are considered major constraints to alleviating poverty in this region (1,2). Because of concerted and coordinated continental control efforts, its incidence has steadily decreased.
