A larger study in Uganda and Tanzania comparing 16 HIV coinfected patients to 49 HIV-negative patients found no difference in clinical manifestation or mortality related to trypanosomiasis. Humans are infected by two types, Trypanosoma brucei gambiense (TbG) and Trypanosoma brucei rhodesiense (TbR). In second-stage disease, invasion of the central nervous system causes a variety of neuropsychiatric manifestations to appear in addition to the first-stage signs and symptoms, with fever occurring less frequently over time.
It is characterized by fever and headache followed by sleep disturbances. Edeghere H. et al. There are two types of trypanosomiasis in Africa: East African type is caused by T. b. rhodesiense and prevalent in eastern and southern Africa; while West African type is caused by T. b. gambiense and prevalent in western and central Africa.

It is caused by infection with protozoan parasites belonging to the genus Trypanosoma.They are transmitted to humans by tsetse fly (Glossina genus) bites which have acquired their infection from human beings or from animals harbouring human pathogenic parasites. A study of African trypanosomiasis patients in Kenya found only 4 of 31 patients (13%) were HIV coinfected; by comparison, 100% of these patients had malaria coinfection. TbG causes over 98% of reported cases. SEASONAL FLUCTUATION IN TSETSE FLY POPULATIONS AND HUMAN AFRICAN TRYPANOSOMIASIS: A MATHEMATICAL MODEL T. MADSEN, D. I. WALLACE, N. ZUPAN Dartmouth College Hanover, NH, 03755, USA Human African trypanosomiasis, commonly known as sleeping sickness, is a vector- borne disease endemic to Sub-Saharan Africa. Human African trypanosomiasis is caused by microscopic parasites of the species Trypanosoma brucei.It is transmitted by the tsetse fly (genus Glossina).As the disease progresses, it causes meningoencephalitis and, eventually, coma and/or death, hence its common name, “sleeping sickness.” This is a list of human infectious diseases with their case fatality rates (CFRs). For both types of disease, the stage is determined by examining cerebrospinal fluid (CSF) and observing trypomastigotes. The age adjusted Death Rate is 7.70 per 100,000 of population ranks Central African Republic #1 in the world.

(1960) The influence of tsetse flies on the distribution of African cattle. Human African trypanosomiasis, also known as sleeping sickness, is a vector-borne parasitic disease. Without treatment, African trypanosomiasis is a universally fatal illness. The disease is widespread in sub-Saharan countries, with the incidence rate as high as 80% in epidemic areas.

African trypanosomiasis, also known as African sleeping sickness or simply sleeping sickness, is an insect-borne parasitic infection of humans and other animals.
