Descriptive Epidemiology and Phylodynamics of the “First Wave” of an Outbreak of Highly Pathogenic Avian Influenza (H5N1 Clade 2.3.4.4b) in British Columbia and the Yukon, Canada, April to September 2022

<div>Contextualization of British Columbia (B.C.)/Yukon reassortants with global H5N1 sequences in GISAID between September 2021 and September 2022. B.C./Yukon genetic clusters relative to global GISAID sequences and the fully Eurasian A/chicken/NL/FAV-0033/2021 sequence detected at the start of the N. American outbreak highlight N. American reassortants in some or all of the clusters in NP (a), PB2 (b), NS (c), and PB1 (d) segments of the virus. Trees are rooted by the KU201896 (H5) reference sequence.</div>
