基孔肯雅热是一种由伊蚊传播的病毒性疾病，2005-2006年期间，基孔肯雅热在西印度洋岛屿和印度影响了数十万人。最初的疫情于2004年在肯尼亚沿海地区(拉穆，然后是蒙巴萨)爆发。我们利用流行病学调查和卫星数据调查了与肯尼亚沿海出现基孔肯雅热有关的生态气候条件。在疫情爆发之前，异常干燥、温暖的条件，包括一些沿海地区自1998年以来最干燥的天气。家庭储水的不频繁补充和气温升高可能为基孔肯雅病毒的传播提供了便利。这些结果表明，受干旱影响的人口患基孔肯雅热的风险可能更高，并强调在抗旱行动中需要安全的水储存。
Epidemics of chikungunya fever, an Aedes spp.-borne viral disease, affected hundreds of thousands of people in western Indian Ocean islands and India during 2005-2006. The initial outbreaks occurred in coastal Kenya (Lamu, then Mombasa) in 2004. We investigated eco-climatic conditions associated with chikungunya fever emergence along coastal Kenya using epidemiologic investigations and satellite data. Unusually dry, warm conditions preceded the outbreaks, including the driest since 1998 for some of the coastal regions. Infrequent replenishment of domestic water stores and elevated temperatures may have facilitated Chikungunya virus transmission. These results suggest that drought-affected populations may be at heightened risk for chikungunya fever, and underscore the need for safe water storage during drought relief operations.
