human african trypanosomiasis a neglected disease
نویسنده
چکیده
Typology There are two forms of HAT, one of which is endemic mainly in East Africa and is caused by Trypanosoma brucei rhodesiense. This form represents less than 10% of the reported cases of sleeping sickness. The other form is endemic mainly in West and Central Africa and is caused by Trypanosoma brucei gambiense. This form represents more than 90% of the reported cases in Africa. These protozoan parasites are both transmitted by the tsetse fly (Glossina genus), which name refers to the sound it makes. The two trypanosome species have indistinguishable morphologic appearances. However, the infections differ in clinical presentation, prognosis and treatment.

متن کاملHuman African trypanosomiasis.
Human African trypanosomiasis (sleeping sickness) occurs in sub-Saharan Africa. It is caused by the protozoan parasite Trypanosoma brucei, transmitted by tsetse flies. Almost all cases are due to Trypanosoma brucei gambiense, which is indigenous to west and central Africa. Prevalence is strongly dependent on control measures, which are often neglected during periods of political instability, th...
