Glycan microarray analysis of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus isolated from poultry farm workers, Washington, USA, 2024. Clade 2.3.4.4b genotype D1.1 H5N1 virus A/Washington/240/2024 was isolated from a confirmed Washington human case. Glycans containing α-2,3 sialic acid and α-2,6 sialic acid are shown. Error bars reflect SDs from 6 independent replicates on the microarray. Details of the glycan structures are listed in Appendix Table 2.
