[Febrile syndromes in the traveler returning from tropical regions admitted in a monographic unit]

The aim was to analyse those syndromes with fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures.

An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions with fever, amongst all travellers evaluated in our department between 1998 and 2013. We analysed demographic features, information related to the trip, as well as the presenting complaints and the diagnoses.

A total of 247 international travellers presenting with fever were analysed. The most common diagnoses were self-limiting fever (29.1%), malaria (25.1%), invasive gastroenteritis (15.4%), other bacterial infections (7.4%) and genitourinary parenchymal infections (4.5%). Of all the cases, only 8.5% required hospitalization, and no case of mortality was recorded.

In the series presented, there are common data with other published data (malaria as a fundamental disease, difficulties in diagnosis) and different ones (less number of pre-trip consultations and admissions, higher incidence of prostatitis and fewer dengue cases).
