The five avian influenza A/H9N2 viruses isolated from wild birds in Jiangxi, China in 2015 are novel reassortants which most likely evolved from multiple lineages. They shared a high similarity with isolates from poultry, suggesting a frequent contact and continuous viral circulation at the bird-poultry interface. Given the continuous reassortment of H9N2 viruses, it will of substantial importance to implement routine surveillance in wild birds to successfully control avian influenza viruses and better the early warning system of the emerging reassortants with pandemic potential.
2015 年，中国江西从野鸟中分离出的 5 株甲型流感病毒 A/H9N2 为新型重配病毒株，可能来源于多个谱系。这些病毒株与家禽来源的病毒株具有高度相似性，表明在禽-鸟接触界面上存在频繁的接触和持续的病毒循环。鉴于 H9N2 病毒的持续重配，对野鸟进行常规监测对于成功控制流感病毒和改善具有大流行潜力的新型重配病毒的早期预警系统具有重要意义。
