African trypanosomiasis in two travelers from the United States.Clin Infect Dis. 1999 Oct; 29(4):840-4.CI
African trypanosomiasis is a rare but well-documented cause of fever in United States travelers returning from areas where it is endemic. We report two recently diagnosed cases that involved tourists who went on safari in Tanzania. Review of these and 29 other published cases indicates that disease in returning United States travelers is nearly always of the East African form, a fulminant illness for which prompt diagnosis is necessary. In the United States, timely and appropriate therapy for this disease has resulted in favorable outcomes for most patients. Chemoprophylaxis for East African trypanosomiasis is not recommended, but travelers visiting areas of endemicity should practice appropriate preventive measures to prevent tsetse fly bites.
