Detailed explanation-1: -African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.

Detailed explanation-2: -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.

Detailed explanation-3: -African trypanosomiasis, also called sleeping sickness, is a disease caused by a parasite. People can get this parasite when an infected Tsetse fly bites them. Symptoms include fatigue, high fever, headaches, and muscle aches. If the disease is not treated, it can cause death.

Detailed explanation-4: -Once the tsetse fly ingests the trypanosomes, they multiply and develop into epimastigotes. Humans are infected after the bite from a tsetse fly. The injected parasites then rapidly divide in the bloodstream and lymphatics.

Detailed explanation-5: -brucei, which causes sleeping sickness in humans and nagana in cattle. T. cruzi, which causes Chagas disease in humans. Trypanosoma culicavium, which infects birds and mosquitoes.
