What are the causes of trypanosomiasis?
Key facts. African trypanosomiasis is caused by parasites of genus Trypanosoma and transmitted by infected tsetse flies and is endemic in 36 sub-Saharan African countries where there are tsetse flies that transmit the disease. Without treatment, the disease is considered fatal.
In which stage of trypanosomiasis does sleeping occur?
History. Symptoms of stage 1 (early or hemolymphatic stage) African trypanosomiasis (sleeping sickness) include the following: Painful skin chancre that appears about 5-15 days after the bite, resolving spontaneously after several weeks (less commonly seen in T brucei gambiense infection)
Can African sleeping sickness be treated?
Antitrypanosomal treatment is indicated for all persons diagnosed with African trypanosomiasis. Choice of therapy depends on the infecting subspecies of the parasite and on the disease stage. The first line drugs for both first and second stage disease are highly effective. Pentamidine is used to treat first stage T.
What is the treatment for Trypanosomiasis?
The acute phase of trypanosomiasis (Chagas disease) is treated with nifurtimox or benznidazole. Cases of congenital Chagas disease have been successfully treated with either drug. A single case of successful treatment of an adult with posaconazole (after failure of therapy with benznidazole) has been reported.
Can sleeping sickness be cured?
The oral therapy — called fexinidazole — cured 91% of people with severe sleeping sickness, compared with 98% who were treated with the combination therapy. It also cured 99% of people in an early stage of the disease who would typically undergo a spinal tap to determine whether they needed infusions.

What are the two types of trypanosomiasis?
The two primary forms of African trypanosomiasis are East African sleeping sickness, caused by Trypanosoma brucei Gambiense, and West African sleeping sickness, caused by Trypanosoma brucei Rhodesiense. East African sleeping sickness is caused by the subspecies T. b. Rhodesiense.
