We identified clade 2.3.4.4 highly pathogenic avian influenza A(H5N6) viruses from whooper swans (Cygnus cygnus) found dead in Mongolia. The identification of these infections in wild birds in this area is of concern because of the potential for virus dissemination during fall migration.
我们从蒙古国死亡的疣鼻天鹅(Cygnus cygnus)中鉴定出了 2.3.4.4 分支的高致病性禽流感病毒(H5N6)。由于在秋季迁徙期间病毒传播的可能性,在该地区的野生鸟类中发现这些感染令人担忧。
