Dengue fever has been endemo-epidemic in the whole Region of America. In 2010, Guadeloupe and Martinique experienced historical epidemics, with an estimated attack rate of 10% in two islands. When considering the temporal evolution of epidemiological indicators, an unusual increase in the number of dengue cases could be detected very early. Two main factors might have facilitated the settlement of a viral transmission despite the dry season: a low immunity of the population against the circulating serotype and particular climatic conditions, notably very high temperatures which could have improved both virus and vector efficiency. This unusual situation was considered as a warning sign, and indeed led to major outbreaks in both islands a few weeks later. This event underlines that follow-up of epidemiological indicators is necessary to detect the unusual situations as soon as possible. Furthermore, development of biological and modelling tools should be promoted, as well as integrated management strategies for dengue prevention and control.
登革热在整个美洲地区呈地方性流行。2010 年，瓜德罗普岛和马提尼克岛经历了历史上的登革热流行，两个岛屿的估计发病率为 10%。当考虑到流行病学指标的时间演变时，可以很早就发现登革热病例数量的异常增加。有两个主要因素可能促进了病毒的传播，尽管是在旱季：人群对流行血清型的免疫力低，以及特殊的气候条件，特别是非常高的温度，这可能提高了病毒和媒介的效率。这种异常情况被视为一个警告信号，确实导致几周后两个岛屿都爆发了重大疫情。这一事件表明，需要监测流行病学指标，以便尽快发现异常情况。此外，应促进生物和建模工具的开发，以及制定综合的登革热预防和控制管理策略。
