Abstract: Human African Trypanosomiasis (HAT) is a parasitic disease usually confined to endemic areas in sub-Saharan Africa, but it occasionally may occur among travelers, migrants, or expatriates. Although it is an uncommon diagnosis in returning travelers attending travel and tropical medicine clinics [1], the number of HAT diagnoses in travelers has been rising in recent years [2], most likely in connection with an increase of tourists visiting endemic areas and improved reporting systems. Trypanosoma brucei is the etiological agent of HAT, and is transmitted by tsetse flies of the genus Glossina. Two species can cause the disease: T. brucei gambiense in West and Central Africa (g-HAT) and T. brucei rhodesiense (r-HAT) in Eastern and Southern Africa. The disease usually presents in two stages: a first or hemolymphatic stage, where the parasite is located in the lymphatic system and blood; and a second or meningo-encephalitic stage, which occurs when trypanosomes penetrate the central nervous system.
