West Nile virus is a flavivirus transmitted to humans mainly by mosquito bites. Outbreaks are observed in several European countries, and Greece is one of the most affected countries during the recent years. Thessaly was one of the most affected regions in Greece in 2019. A total of 3,025 Culex spp. mosquitoes collected in Thessaly were grouped into 47 pools and tested for West Nile virus (WNV). Eight (17%) pools were found positive. Whole genome sequences were obtained from two positive pools. Phylogenetic analysis showed that the causative strain was an evolutionary variant of the strains circulating in 2018 belonging to the Balkan subgroup of the Central European subclade of WNV lineage 2.
西尼罗河病毒是一种主要通过蚊虫叮咬传播给人类的黄病毒。在几个欧洲国家都观察到了疫情爆发，希腊是近年来受影响最严重的国家之一。塞萨利是2019年希腊受影响最严重的地区之一。在塞萨利采集的总共3025只库蚊属蚊子被分成47组，并检测了西尼罗河病毒（WNV）。发现8组（17%）呈阳性。从两个阳性组中获得了全基因组序列。系统发育分析表明，致病菌株是2018年流行菌株的进化变体，属于西尼罗河病毒2型中欧亚分支的巴尔干亚组。
