Abstract

We report reoccurrence of highly pathogenic avian influenza A(H5N2) virus clade 2.3.4.4 in a wild mallard in Alaska, USA, in August 2016. Identification of this virus in a migratory species confirms low-frequency persistence in North America and the potential for re-dissemination of the virus during the 2016 fall migration.

摘要

我们报告了2016年8月在美国阿拉斯加一只野生绿头鸭体内再次出现高致病性甲型禽流感病毒(H5N2)2.3.4.4分支。在一个迁徙物种中发现这种病毒,证实了该病毒在北美以低频率持续存在,并有可能在2016年秋季迁徙期间再次传播。
