Fever in Returning Travelers

Fevers in individuals with recent tropical travel require rapid assessment because many of the potential causes are treatable and/or have important public health implications. History and clinical findings are essential to identify the likely causes of the fever and, thus, recognize those that require urgent intervention.This review outlines obtaining the travel history, incubation periods, undifferentiated fever, and evaluation based on syndromes. Figures show the most common diagnoses and range of incubation periods; the top specific diagnoses in febrile returned travelers by geographic region; countries/areas at risk for dengue transmission; images of Aedes aegypti and Aedes albopictus, vectors of dengue virus and chikungunya virus; countries and territories where chikungunya cases have been reported (as of March 10, 2015), excluding where imported cases only are documented; cases of Ebola virus disease in Africa, 1976–2015, by species and size; and an algorithm for approach to workup.
