Hemagglutinin Protein

Position 190 is described as a mutation site with epidemiological significance. Sequencing revealed potential mutations at two critical sites on the hemagglutinin protein. Q226 is a hemagglutinin position known to affect receptor binding specificity. Both identified mutation sites on the viral sequence are known to affect binding to human respiratory receptors. The mutations on hemagglutinin are epidemiologically significant because they influence human-to-human transmissibility potential.
