The sequencing results indicates that the HA proteins from both red fox kits belongs to Eurasian Gs/GD lineage HPAI H5N1 with cleavage site motif “PLREKRRKR/GLF” compatible with HPAI viruses. . The virus from both red foxes 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 lineage. https://oie-wahis.oie.int/#/report-info?reportId=53345
