We found that Eretmapodites subsimplicipes, a highly abundant mosquito species in Mayotte, can transmit RVF virus. Additionally, we confirmed that Aedes albopictus can also transmit RVF virus, as observed in other countries. These findings highlight the importance of both species in the transmission of RVF in Mayotte and contribute to the understanding of the RVF epidemiological cycle and prevention measures.
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 empha-sizing 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.
