Active surveillance in high-risk sites in Cambodia has identified multiple low-pathogenicity influenza A(H7) viruses, mainly in ducks. None fall within the A/Anhui/1/2013(H7N9) lineage; however, some A(H7) viruses from 2018 show temporal and phylogenetic similarity to the H7N4 virus that caused a nonfatal infection in Jiangsu Province, China, in December 2017.
在柬埔寨高危地区的主动监测中发现了多种低致病性甲型流感病毒(H7),主要存在于鸭群中。这些病毒均不属于 A/Anhui/1/2013(H7N9)谱系;然而,2018 年的一些 H7 病毒与 2017 年 12 月在中国江苏省造成非致命感染的 H7N4 病毒在时间和系统发育上具有相似性。
