We had for aim to describe the epidemiological, clinical, biological, and outcome features of dengue fever in Abidjan, in 2010.We retrospectively studied the files of patients hospitalized for dengue fever in 2010, in Abidjan. The diagnosis was made on clinical symptoms and positive dengue PCR and/or IgM.Seven patients were included (5 men, 2 women, median age of 51years [31-65years]). They presented with a febrile pain syndrome (n=7), jaundice (n=3), rash (n=2), and hematemesis complicated by thrombocytopenia (n=6) and leukopenia (n=5). Three patients had a positive IgM serology and 4 had a positive dengue PCR for DENV-3. The outcome was favorable for 6 patients, and 1 patient died of severe hemorrhage.The authors advocate the implementation of epidemiological surveillance of dengue and vector control in the Ivory Coast.
