  African Trypanosomiasis
The term “sleeping sickness” is derived from the West African form of trypanosomiasis, primarily because invasion of the cerebrospinal fluid and brain after infection of the blood is often delayed, resulting in symptoms of extreme fatigue that can last for several years before the severe phase of the disease sets in; toxemia, coma and death.
Animal trypanosomiasis, caused by a wider number of trypanosome species and carried with higher prevalence by a greater number of glossina species, is invariably the greater epidemic across the African continent with dire economic consequences.
Historically, the impact of animal trypanosomiasis were so profound that it influenced the migration routes of cattle-owning tribes into the continent who were forced to avoid the G. morsitans “fly-belts” (Ford 1960), as well as the movements of early European and Arab settlers into the continent who depended on horses and oxen (McKelvey 1973).
