Human African Trypanosomiasis (HAT), also called African sleeping sickness, is a parasitic disease that is transmitted by infected tsetse flies. HAT can occur as a chronic or acute infection depending on the sub-species of parasite responsible for the infection.
There are two types of African trypanosomiasis (also called sleeping sickness); each named for the region of Africa in which it was found historically. Individuals can become infected with West African trypanosomiasis if they receive a bite from an infected tsetse fly, which is only found in Africa.est African trypanosomiasis, also called Gambian sleeping sickness, is caused by a parasite called Trypanosoma brucei gambiense carried by the tsetse fly. In recent years, 7,000-10,000 new cases of West African trypanosomiasis have been reported to the World Health Organization annually.
