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 is named for the region of Africa in which they were found historically. East African trypanosomiasis is caused by the parasite Trypanosoma brucei rhodesiense, which is carried by the tsetse fly. person will get East African trypanosomiasis if he or she is bitten by a tsetse fly infected with the Trypanosoma brucei rhodesiense parasite. The proportion of tsetse flies that are infected with this parasite is low. The tsetse fly is found only in rural Africa.
