Molecular analysis of HA amino acid sequences of the isolated virus and reference strains. Red boxes are potential glycosylation sites. Previously defined antigenic sites are indicated: site Sa (lime shade), site Sb (yellow shade), site Ca (pale green shade), site Cb (canary shade). Residues marked with “” are receptor-binding sites. The site with a blue arrow is the HA cleavage site.
