Arboviruses transmitted by Aedes mosquitoes are a growing global concern; however, there remain large gaps in surveillance of both arboviruses and their vectors in West Africa. We reviewed over 50 years of data including outbreak reports, peer-reviewed literature, and prior data compilations describing Zika, dengue, and chikungunya, and their vectors in West Africa. Large outbreaks of dengue, Zika, and chikungunya have recently occurred in the region with over 27,000 cases of Aedes-borne disease documented since 2007. Recent arboviral outbreaks have become more concentrated in urban areas, and Aedes albopictus, a relatively new arrival in the region, has emerged as an important vector in several areas. Seroprevalence surveys suggest reported cases are a gross underestimate of the underlying arboviral disease burden. These findings indicate a shifting epidemiology of arboviral disease in West Africa and highlight a need for increased research and implementation of vector and disease control. Rapid urbanization and climate change may further alter disease patterns, underscoring the need for improved diagnostic capacity, and vector and disease surveillance to address this evolving health challenge.

西非伊蚊传播的疾病暴发：呼吁加强监测。

伊蚊（Aedes）蚊子传播的虫媒病毒日益引起全球关注。然而，在西非，虫媒病毒及其媒介的监测仍存在很大差距。我们回顾了50多年的数据，包括暴发报告，同行评审的文献以及描述Zika，登革热和基孔肯雅热的先前数据汇编以及它们在西非的媒介。自2007年以来，该地区最近爆发了大规模的登革热，寨卡病毒和基孔肯雅热疫情，记录到27,000例伊蚊传播的病例。最近的虫媒病毒暴发更加集中在城市地区，而白纹伊蚊在该地区相对较新到来在多个领域已成为重要的媒介。血清阳性率调查表明，报告的病例严重低估了潜在的虫媒病毒疾病负担。这些发现表明西非的虫媒病毒病流行病学正在发生变化，并突出显示了对媒介和疾病控制的更多研究和实施的需要。快速的城市化和气候变化可能会进一步改变疾病模式，从而强调需要提高诊断能力，以及对病媒和疾病进行监测以应对不断发展的健康挑战。
