In spring 2022, Europe faced an unprecedented heatwave, increasing the risk of West Nile virus (WNV) outbreaks. As early as 7 June 2022, WNV was detected in mosquitoes in northern Italy, and - in the following days - in two blood donors, a patient with encephalitis, wild birds and additional mosquito pools. Genome sequencing demonstrated co-circulation of WNV lineage 2 and a newly introduced WNV lineage 1, which was discovered in the region in 2021.
2022 年春季，欧洲遭遇了一场前所未有的热浪，增加了西尼罗河病毒（WNV）爆发的风险。早在 2022 年 6 月 7 日，意大利北部的蚊子中就检测到了 WNV，随后几天，在两名献血者、一名脑炎患者、野生鸟类和其他蚊子池中也检测到了该病毒。基因组测序表明，WNV 谱系 2 和一种新引入的 WNV 谱系 1 同时流行，后者于 2021 年在该地区首次发现。
