Rift Valley fever (RVF) recently re-emerged in Mayotte. We described, for the first time, that the mosquito species Eretmapodites subsimplicipes, a highly abundant species in Mayotte, is a competent vector for the transmission of RVF virus using three distinct populations native to Mayotte. We also showed that Aedes albopictus specimens are able to transmit RVF virus (RVFV) as previously observed in mosquito populations of other countries emphasizing the need of the increase vigilance for this highly invasive species of global distribution. Altogether, these results underline the epidemiological importance of both species for RVFV transmission in Mayotte and contribute to better understand the RVF epidemiological cycle and help to implement efficient prevention measures.
裂谷热（RVF）最近于马约特岛再次出现。我们首次描述了马约特岛数量极为丰富的拟简长足蚊种，利用来自马约特岛的三个不同种群，是裂谷热病毒传播的有效媒介。我们还表明，白纹伊蚊样本能够传播裂谷热病毒（RVFV），正如之前在其他国家的蚊虫种群中所观察到的那样，这凸显了对这种全球分布的高度入侵物种提高警惕的必要性。总之，这些结果突显了这两个蚊种在马约特岛裂谷热病毒传播中的流行病学重要性，有助于更好地理解裂谷热的流行病学循环，并有助于实施有效的预防措施。
