Caused by the protozoan parasite Trypanosoma brucei
Two distinct sub-species exist T. brucei rhodesiense and T. brucei gambiense
rhodesiense - Eastern and Southeastern Africa
Transmitted by tsetse flies that live in woodlands on the savanah
gambiense - Central and Western Africa (More common of the two infections)
Transmitted by tsetse flies that live in denser vegetation and along rivers
Crude demarcation line runs through the Great Rift Valley
Endemic in 36 countries in Sub-Saharan Africa and about 30,000 are currently infected
Spread by the Tsetse fly
Data from 2009 and 2011 suggest that the prevalence is decreasing
The Democratic Republic of the Congo reported about 80% of new cases in 2012
Vertical Transmission (Mother to fetus) is also possible
