H5N2 Clade In Kostromskaya Russia

Recommended Posts

In the 2016/2017 season H5N8 Clade spread widely in Asia, Europe, and Africa.  In the 2017/2018 season H5N6 with a Eurasian N6 was reported after a late appearance in 2016/2017 season in Europe.  Now a HPAI H5N2 has been reported in western Russia, suggesting multiple clade serotypes will be co-circulating in Europe and beyond in 2018.
