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”. Approximately 70 million people are estimated to be at different levels of risk of contracting HAT in Africa.
