Japanese encephalitis virus (JEV) continues to circulate throughout Southeast Asia and the Western Pacific where approximately 3 billion people in 24 countries are at risk of infection. Surveillance targeting the mosquito vectors of JEV was conducted at four military installations on Okinawa, Japan, between 2016 and 2021. Out of a total of 10,426 mosquitoes from 20 different species, zero were positive for JEV. The most abundant mosquito species collected were Aedes albopictus (36.4%) followed by Culex sitiens (24.3%) and Armigeres subalbatus (19%). Statistically significant differences in mosquito species populations according to location were observed. Changes in land use over time appear to be correlated with the species and number of mosquitoes trapped in each location. JEV appears to be absent from mosquito populations on Okinawa, but further research on domestic pigs and ardeid birds is warranted.
日本脑炎病毒（JEV）在东南亚和西太平洋地区持续传播，在这两个地区，约有 24 个国家的 30 亿人面临感染风险。2016 年至 2021 年，在日本冲绳的四个军事设施中对 JEV 的蚊子媒介进行了监测。在总共从 20 种蚊子中采集的 10426 只蚊子中，没有一只蚊子对 JEV 呈阳性。采集到的最丰富的蚊子种类是白纹伊蚊（36.4%），其次是库蚊（24.3%）和三带喙库蚊（19%）。根据位置观察到蚊子种群的统计学显著差异。随着时间的推移，土地利用的变化似乎与每个地点捕获的蚊子种类和数量有关。JEV 似乎不存在于冲绳的蚊子种群中，但有必要对当地的猪和鹭科鸟类进行进一步研究。
