<P> Influenza viruses bind through hemagglutinin onto sialic acid sugars on the surfaces of epithelial cells , typically in the nose , throat , and lungs of mammals , and intestines of birds ( Stage 1 in infection figure ) . After the hemagglutinin is cleaved by a protease , the cell imports the virus by endocytosis . </P>
