In the influenza virus, H and N respectively represent hemagglutinin (H) and neuraminidase (N) of the outer membrane of the virus, depending on the antigenicity of outer membrane hemagglutinin (H) and neuraminidase (N) proteins Currently, it can be divided into 16 H subtypes (H1 ~ H16) and 9 N subtypes (N1 ~ N9). The reported human infection with the H7N9 avian influenza virus was a novel reassortant virus. The gene encoding HA was derived from H7N3, the gene encoding NA was from H7N9, and the six internal genes from the H9N2 avian influenza virus.
