Item The Epidemiology of Sleeping Sickness in Samia Location, Kenya.(1968) Wijers, D.J.B.In 1964 a T. rhodesiense sleeping sickness epidemic occurred in Alego Central Nyanza. Here the disease was transmitted by Glossina fuscipes which had left its riverine habitat and had settled in the dense hedges around the homesteads so that the flies had come into very close contact with man and his livestock. The disease was found to have a reservoir in cattle that could harbor the trypanosome for many months without showing any signs of illness. To control the epidemic and to prevent further spread, the Government decided to eradicate all tsetse in Central Nyanza by spraying the bush with insecticides. To prevent re-invasion by the fly from Uganda, all bush was cleared in a barrier zone at the western border of the sprayed area.Item Factors that may Influence the Infection Rate of Glossina Palpalis with Trypanosoma Gambiense: I.—The Age of the Fly at the Time of the Infected Feed.(1958) Wijers, D.J.B.; West African Institute for trypanosomiasis Research, NigeriaMuch experimental work on the polymorphic trypanosomes has been hindered by the low percentage of flies that become infected. The conditions necessary for the infection of the fly and the factors which may increase the infection rate have been studied by several workers, but the published evidence is often conflicting.Item The History of Sleeping Sickness in Yimbo Location (Central Nyanza, Kenya) as Told by the Oldest Inhabitants of the Location(1969) Wijers, D.J.B.; Medical Research Centre, Nairobi"Long ago, before the Europeans came, there lived in Yimbo two mighty Luo clans: the Kanyathuon and the Kajongo. Relations between the two clans werestrained because, when the clans conquered Yimbo, the Kajongo had killed off all the original inhabitants and they blamed the Kanyathuon who had spared the lives of the conquered people and allowed them to live quietly among their conquerors. In the clan war which resulted the Kajongo lost battle after battle, for the Kanyathuon, aided by the men whose lives they had spared, were far too strong for them."
