EPIDEMIOLOGICAL COMMENTS
A fourth non-poultry infected premises from the Atlantic area is a non-commercial backyard flock located in Nova Scotia. We also report a first wild bird infected with Highly pathogenic avian influenza virus strain of H5 subtype in New Brunswick and additional wild birds in Prince Edward Island and Nova Scotia. The HA gene segment is A/goose/Guangdong/1996 (Gs/GD) lineage belonging to 2.3.4.4B clade. Phylogenic analysis indicates this virus corresponds to the Eurasian lineage circulating in 2021 in Europe and to those currently circulating in North America. Wildlife surveillance as well as the Canadian Avian Influenza Surveillance System (CanNAISS) activities for poultry are ongoing in Canada. According to article 10.4.1.4 of the Terrestrial Animal Health Code, Member Country should not impose bans on the international trade of poultry commodities in response to notification of infection with any Influenza A viruses in birds other than poultry.
