The West Nile virus (WNV) transmission cycle includes a wide range of migratory wetland birds as reservoirs, mosquitoes as biological vectors, and equines and humans as dead-end hosts. Despite the presence of potential vector species, there is no information about the existence of WNV in mosquito vectors in Iran. The Iranian West Azerbaijan Province is located in the northwestern part of Iran and has borders with Turkey, Iraq, Armenia, and the Republic of Azerbaijan. The current study was conducted to identify the wetland mosquitoes of the West Azerbaijan Province and their infection with WNV. In this study, 2143 specimens were collected, comprising 1541 adults and 602 larvae. Six species belonging to four genera were collected and identified: Anopheles maculipennis sensu lato (s.l.), Culex (Cx.) hortensis, Cx. pipiens s.l., Cx. theileri, Culiseta longiareolata, and Aedes (Ae.) (Ochlerotatus) caspius. In total, 45 pools of mosquitoes were examined. Two of the adult pools collected from the same location showed the presence of WNV in Ae. (Och.) caspius, from Sangar, Makoo County, as confirmed by PCR and sequencing. Due to the discovery of WNV in the mosquito population of the region, and the presence of wetlands and significant populations of migratory birds, the health sector should carefully monitor the factors involved in the cycle of this disease.
西尼罗河病毒（WNV）的传播循环包括多种作为宿主的迁徙湿地鸟类、作为生物媒介的蚊子，以及作为终末宿主的马和人类。尽管存在潜在的媒介物种，但伊朗尚无关于蚊子媒介中存在西尼罗河病毒的信息。伊朗西阿塞拜疆省位于伊朗西北部，与土耳其、伊拉克、亚美尼亚和阿塞拜疆共和国接壤。本研究旨在鉴定西阿塞拜疆省的湿地蚊子及其感染西尼罗河病毒的情况。在本研究中，共收集了2143个样本，包括1541只成虫和602只幼虫。收集并鉴定了属于四个属的六个物种：嗜人按蚊复合组、霍氏库蚊、尖音库蚊复合组、泰勒库蚊、长跗库蚊和里海伊蚊（奥氏伊蚊）。总共检查了45组蚊子。从同一地点收集的两组成虫样本显示，来自马库县桑加尔的里海伊蚊（奥氏伊蚊）中存在西尼罗河病毒，经PCR和测序确认。由于在该地区的蚊子种群中发现了西尼罗河病毒，以及存在湿地和大量候鸟，卫生部门应仔细监测该疾病传播循环中涉及的因素。
