Dengue is a public health concern across the globe, and an escalating problem in the Americas. As part of a wider programme (covering Latin America and South East Asia) to characterize the epidemiology of dengue in dengue endemic areas, we undertook a systematic literature review to assess epidemiological trends (incidence, timing and duration of outbreaks/epidemics, age and sex distribution, serotype distribution, seroprevalence and disease severity) for dengue across the French Territories of the Americas (FTA), in French Guiana, Guadeloupe, Martinique, Saint Martin and Saint Barthélemy between 2000 and 2012 (CRD42012002341: http://www.crd.york.ac.uk/prospero/display_record.asp?ID=CRD42012002341). Of 413 relevant data sources identified, 45 were eligible for inclusion. A large proportion of the available data were from national surveillance reports, and 12 publications were from peer-reviewed journals. During the review period, 3–5 epidemics were identified in each of the island territories and French Guiana, and epidemics were often associated with a shift in the predominant circulating dengue virus serotype. Substantial gaps in epidemiological knowledge were identified. In particular, information regarding dengue virus genotype distribution, seroprevalence and age distribution of dengue were lacking. Additionally, much of the available data were from epidemic years; data from inter-epidemic periods were sparse. Nevertheless, the available epidemiological data showed that dengue is endemic across the FTA and suggest an evolution towards hyperendemicity, highlighting the need to continue the efforts with the existing surveillance programmes to assist in planning an effective vaccination programme once a dengue vaccine is deployed.

Dengue disease is a mosquito-borne viral illness and is a major health concern in the Americas. We conducted a literature analysis and review to describe the epidemiology of dengue in the French Territories of the Americas (FTA), comprising French Guiana, Guadeloupe, Martinique, Saint Martin and Saint Barthélemy, to determine the impact of dengue on the population and to identify research priorities. We used well-defined methods to search for and identify relevant research conducted between 2000 and 2012. We identified an increase in the frequency, magnitude and severity of dengue epidemics across all the territories, an increase in the co-circulation of serotypes and the evolution to a hyperendemic state. Countries sharing geographical and environmental characteristics (e.g., Martinique and Guadeloupe, and Saint Barthélemy and Saint Martin) also shared characteristics in dengue epidemiology and its evolution, including timing of epidemics and circulating serotypes. Gaps in epidemiological knowledge provide several avenues for research, such as dengue virus genotype distribution, seroprevalence and age distribution of dengue cases. Epidemiological and virological surveillance of dengue in the FTA is evolving, and improved knowledge of the disease in these territories will improve anticipation of epidemics and aid implementation of control measures.
