EPIDEMIOLOGICAL COMMENTS
The infected premises is an exhibition farm located on an island off the Atlantic Coast of Canada. A protection zone (3km) and a surveillance zone (10 km) have been put in place around the infected premises. The virus has HA cleavage site motif “PLREKRRK/GLF” consistent with highly pathogenic avian influenza strains of H5 subtype. 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. 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.
