EPIDEMIOLOGICAL COMMENTS
On March 25th, 2022, the Canadian Food Inspection Agency (CFIA) was notified of high mortality in a commercial turkey farm in Southern Ontario. The CFIA National Centre for Foreign Animal Disease has confirmed that the virus was H5N1. The virus contains unique constellation of gene segments with PB2, PB1, PA and NP belonging to wild bird origin North American lineage influenza A viruses. The remaining gene segments (HA, NA, M and NS) belong to Eurasian Gs/GD lineage HPAI H5N1 viruses belonging to 2.3.4.4B clade circulating in the Atlantic provinces of Canada, USA and Europe. On March 26th, 2022, the CFIA was notified of a high mortality in a second commercial turkey farm in Southern Ontario. The CFIA National Centre for Foreign Animal Disease has confirmed that the virus was H5N1 consistent with other Eurasian Gs/GD lineage HPAI H5N1 viruses belonging to 2.3.4.4B clade circulating in the Atlantic provinces of Canada, USA and Europe Both viruses have HA cleavage site motif “PLREKRRK/GLF” consistent with highly pathogenic avian influenza strains of H5 subtype. The different genomic sequencing suggests distinct introductions. The CFIA has immediately quarantined the infected farms and is implementing strict movement controls and a stamping out policy. A protection zone (3km) and a surveillance zone (10 km) are being put in place around the infected premises. Surveillance is ongoing in the affected area. Wildlife surveillance as well as the Canadian Avian Influenza Surveillance System (CanNAISS) activities for poultry are ongoing in Canada.
