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.
Both of the subspecies which cause African Trypanosomiasis have different progressions and symptoms but ultimately if left untreated both result in coma followed by death [1]. Trypanosoma brucei rhodesiense which causes close to just 2% of all human sleeping sickness cases is characterized by rapid progression.
