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，瑞典在一名因流感样疾病寻求初级医疗护理的患者身上检测到一种具有7:1基因组合的人类季节性重组甲型流感病毒A(H1N2)。该病毒的神经氨酸酶基因来自A(H3N2)，其余基因来自A(H1N1)pdm09。患者已康复。通过常规监测未检测到其他病例。这是2024/25季节欧洲在GISAID报告的三种季节性A(H1N1)pdm09和A(H3N2)重组病毒中迄今唯一确定的A(H1N2)重组病毒。
