Abstract excerpt

An evolutionary analysis was conducted of 354 hemagglutinin (HA) and 208 neuraminidase (NA) genes, including newly generated sequences of 5 HA and 30 NA, of Egyptian H5N1 clade 2.2.1 viruses isolated from poultry and humans. Five distinct phylogenetically distinguishable clusters arose from a monophyletic origin since 2006. Only two clusters remained in circulation after 2009: (i) A cluster of viruses arose in...
