Human trypanosomiasis in south-east Uganda. A further study of the epidemiology of the disease among fishermen and peasant cultivators.

During the past two decades there has been an increase in the incidence and spread of sleeping-sickness due to Trypanosoma rhodesiense throughout the north-eastern shore area of Lake Victoria; this increase has been associated with heightened finishing activity and increasing and irregular settlement of the tsetse-fly belt of south-east Uganda.The author describes a number of epidemiological factors affecting the occurrence of the disease among fishermen, placing emphasis on the correct development of the local fishing industry to avoid, on the one hand, depleting the fish population and, on the other, increasing the incidence of sleeping-sickness.Sociological factors which militate against the development of settlement in Glossina-infested areas of south-east Uganda are also described and plans for future settlement in that area are discussed.
