Upon his visit to Uganda, Churchill described the landscape as a "beautiful garden of death" because so many individuals were chronically infected with African Sleeping Sickness. What is the causative agent of this disease and its corresponding vector?

It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It is a vector-borne parasitic disease transmited by the Tse-tse fly.

Explanation:

African sleeping sickness, named human African trypanosomiasis, is a vector-borne parasitic disease transmited by the Tse-tse fly (that belongs to the Glossina genus). These flies can acquire the parasite by biting infected humans or animals.

It is caused by infection with protozoan parasites belonging to the genus Trypanosoma. It can be Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense. Trypanosoma brucei gambiense has a prevalence of 98% of the reported cases, while Trypanosoma brucei gambiense accounts for the 2%.
