No evidence for HPAI H5N1 2.3.4.4b incursion into Australia in 2022
Abstract
There is an ongoing and profound burden of lineage 2.3.4.4b high pathogenicity avian influenza (HPAI) H5 on wild birds and poultry, globally. Herein we report the continued absence of HPAI in Australia from September - December 2022, in inbound migratory birds. Given the ever changing phenotype of this virus, worldwide studies on the occurence, or here absence of the virus, are of critical importance to understand the virus dispersal and incursion risk and development of response strategies.
