Abstract

In April 2025, a human seasonal reassortant influenza A(H1N2) virus with a 7:1 genetic constellation was detected in Sweden in a patient seeking primary care for influenza-like illness. The neuraminidase gene of this virus was from A(H3N2) and the remaining genes from A(H1N1)pdm09. The patient recovered. No additional cases have been detected through routine surveillance. This is so far the only identified A(H1N2) reassortant among three seasonal A(H1N1)pdm09 and A(H3N2) reassortants reported in GISAID from Europe during the 2024/25 season.

2025年4月，瑞典，一名患者中发现新型甲型h1n1流感季节性重组病毒。

2025年4月，瑞典在一名因流感样疾病寻求初级保健的患者身上发现了一种遗传星座为7:1的人类季节性甲型h1n1流感病毒。该病毒的神经氨酸酶基因来自A(H3N2)，其余基因来自A(H1N1)pdm09。病人康复了。通过常规监测未发现其他病例。这是迄今为止在GISAID报告的来自欧洲的三种季节性A(H1N1)pdm09和A（H3N2）重组中唯一确定的A（H1N2）重组。
