Phylogeny of hemagglutinin (HA) gene sequences of HPAI H5N1 viruses collected from waterfowl experiencing unusually high mortality in Netrokona, Bangladesh during June–July 2011. Viruses detected in Bangladesh during this outbreak investigation are denoted by a triangle in clade 2.3.2.1a. Collapsed branches indicate other large clades of H5N1 virus with strain names not shown. HA clades are indicated by brackets. The tree was calculated using the neighbour-joining method with the Kimura 2-parameter distance model.
