The tsetse fly is large, brown and stealthy. While taking blood from a mammalian host, an infected tsetse fly (genus ''Glossina'') injects metacyclic trypomastigotes into skin tissue. The parasites enter the lymphatic system and pass into the bloodstream.

Sleeping Sickness. Human African trypanosomiasis, or sleeping sickness, is a parasitic infection found in sub-Saharan Africa, transmitted by the tsetse fly. MSF admitted 330 patients for sleeping sickness treatment in 2014.

Generally known as sleeping sickness, human African trypanosomiasis is a parasitic infection transmitted by tsetse flies. Tsetse flies are found in 36 countries in sub-Saharan Africa, putting 65 million people at risk. The infection attacks the central nervous system, causing severe neurological disorders.

The disease is found in two forms, depending on the parasite, either ''Trypanosoma brucei gambiense'' or ''Trypanosoma brucei rhodesiense''. ''T. b. gambiense'' is found in central and western Africa; it causes a chronic condition that can extend in a passive phase for months or years before symptoms emerge.

Instances of sleeping sickness are being reduced by the use of the sterile insect technique. Regular active surveillance, involving case detection and treatment, in addition to tsetse fly control, is the backbone of the strategy for control of sleeping sickness.

Both of these parasites are transmitted to human hosts by bites of infected tsetse flies (Glossina palpalis for T brucei gambiense and Glossina morsitans for T brucei rhodesiense), which are found only in Africa. In West African trypanosomiasis, the reservoirs of infection for these vectors are exclusively human. East African trypanosomiasis, however, is a zoonotic infection with animal vectors.

African trypanosomiasis, also referred to as sleeping sickness, is an illness endemic to sub-Saharan Africa. It is caused by the flagellate protozoan Trypanosoma brucei, which exists in the following 2 morphologically identical subspecies: T brucei rhodesiense (East African or Rhodesian African trypanosomiasis).

Back to Top Causes. Sleeping sickness is caused by two germs (protozoa), Trypanosoma brucei rhodesiense and Trypanosomoa brucei gambiense. The more severe form of the illness is caused by T. b. rhodesiense. Tsetse flies carry the infection. When an infected fly bites you, the infection spreads through your blood.

It is found in southern and eastern Africa; its infection emerges in a few weeks and is more virulent and faster developing. According to recent estimates, the disability adjusted life years (9 to 10 years) (DALYs) lost due to sleeping sickness are 2.0 million. Recent estimates indicate that over 60 million people living in some 250 locations are at risk of contracting the disease, and there are about 300,000 new cases each year.
