Figure 1

Phylogenetic tree of the concatenated genome in study of avian influenza A(H5N1) virus among dairy cattle, Texas, USA. Maximum-likelihood phylogenetic tree inferred for the A/cattle/Texas/5628356283/2024 (H5N1) virus isolated in this study (blue text) and 15 other closely related HPAI H5N1 viruses downloaded from GISAID (https://www.gisaid.org). Bootstrap values are provided for key nodes. The clade of 13 Texas viruses collected during March 2024 is labeled. Red text indicates human case (A/Texas/37/2024) and green text indicates cattle viruses collected from other farm(s) in Texas. Branch lengths are drawn to scale. Scale bar indicates number of substitutions per site.
