Imported Dengue in French University Hospitals: a 6-year survey.
Dengue fever (DF) is a mosquito-transmitted acute disease caused by any of four dengue flavivirus serotypes (DEN-1, DEN-2, DEN-3, and DEN-4) which is becoming a major public health problem in intertropical areas.1 DF is increasingly observed in febrile travelers returning from tropical areas,2 especially those returning from the Caribbean islands and Southeast Asia, but it is rarely diagnosed in travelers returning from Africa.3-8 Diagnosis is often serologic, and in most cases is not confirmed; virus isolation remains exceptional. In a retrospective study of 44 cases of imported DF diagnosed in France, we found that the epidemiologic, clinical and diagnostic characteristics of these cases were similar to those reported in other previous published studies; diagnosis was carried out with serology, and no virus isolation was reported. To draw the attention of physicians from nonendemic areas to the possible occurrence of dengue infection in febrile travelers from all tropical countries, including those in Africa, and to reinforce recommendations required to establish diagnosis with certainty, we report herein a prospective study from 1998-1999 which we compiled with our previously published data.
