Émergence du chikungunya dans les Départements Français d’Amérique : résultats de la surveillance épidémiologique mise en œuvre en avril 2014

Abstract : Although the Americas were free from chikungunya until November 2013, there was an increasing risk of emergence of this arbovirus in the French overseas territories of the Americas due to the presence of a competent vector and increasing international trade with endemic areas. In mid-November 2013, clusters of cases of febrile syndromes with arthralgia were reported in St. Martin. The investigations confirmed the autochthonous circulation of chikungunya, which resulted in the activation of the Programme for monitoring, alert and outbreak management for chikungunya in the French overseas territories. This programme integrates surveillance and management interventions ranked according to the level of their epidemic risk. Epidemiological surveillance is based on primary data sources: outpatient medicine, clinical laboratories and hospitals. Data are also collected during entomological and epidemiological surveys. Depending on the level ranked, different spatiotemporal indicators related to biological confirmations, medical consultations, visits to hospital emergencies, hospitalized cases and their severity are monitored. At the end of April 2014, St. Martin, St. Barthelemy, Martinique and Guadeloupe were or had been in epidemic stage, while French Guiana was in a stage of moderate viral circulation limited to the successive emergence of clusters. Due to the decrease in the number of observed cases, viral circulation was ranked as moderate in St. Martin at the end of April 2014. The number of cases clinically suggestive observed in general practice and their impact in St-Martin, St. Barthelemy, Martinique and Guadeloupe were respectively estimated at 3,160 or 85‰, 470 or 52‰, 19,650 or 49‰, and 7,820 or 19‰ inhabitants. In all, 418 cases were hospitalized; for 229 of them the characteristics were investigated, and 13% were found to be severe. Six deaths, including 4 reported as indirectly related to chikungunya, and 2 deaths in the process of ranking, were reported. With the experience acquired in La Réunion, as well as with the dengue epidemics in the Caribbean and French Guiana, French overseas territories are currently implementing an integrated approach that brings together all the players of surveillance and response face to this sudden emergence of chikungunya.
