Human African trypanosomiasis

Mapping the risk of human African trypanosomiasis

Based on information on the HAT reported cases and the geographic distribution of human population, spatially explicit estimates of population at risk have been calculated and classified in five categories of risk, ranging from “very high” to “very low”.

For gambiense HAT, 55 million people are estimated to be at risk of infection (period 2010-2014), with 1.2 million at very high and high risk, and 9.2 million at moderate risk.

For rhodesiense HAT, over 6 million people are estimated to be at risk of infection (period 2010-2014). Most are in the low and very low risk categories (5.6 million), while only four hundred thousand people are in the moderate risk.
