Created in 2011, this diagram depicts how the human cases of swine-origin H3N2 Influenza virus, reported in Indiana and Pennsylvania in September, 2011, resulted from the reassortment of two different Influenza viruses. The diagram shows three Influenza viruses placed side by side, with eight color-coded RNA segments inside of each virus. Note: All Influenza viruses contain 8 RNA segments. These RNA segments are labeled HA (hemagglutinin), NA (neuraminidase), PB1, PB2, PA, NP, M and NS. See PHIL 13470, for a transmission electron microscopic (TEM) image revealing the ultrastructural details displayed by some actual H3N2 virions, represented by the central figure of this diagram.
