Abstract
H ighly pathogenic avian influenza (HPAI) H5 vi- ruses belonging to clade 2.3.4.4 of the Goose/ Guangdong/96 (GS/Gd) lineage continue to pose a threat to poultry and wild birds worldwide (1-6). Reassortment events between HPAI H5 and low pathogenicity avian influenza (LPAI) viruses of wild-bird origin have led to generation of novel variants that might be periodically spread by wild birds across continents (6).
