Influenza Virus (Human)
Influenza virus is classified into three groups, A, B, and C by the difference of nuclear protein. Prevalent types of Influenza virus are H1, H3 and B strain. The structure of Influenza virus is shown below. Influenza virus is further classified into subtypes by the difference of Neuraminidase (NA) and Haemagglutinin (HA) that are the surface glycoprotein of the virus. H1N1 subtype and H3N2 subtype are known they cause severe febrile illness. A virus particle consists of a head region and a stem region. A head region has a receptor domain to the target cell and in stem region there is a special amino acid sequence that is necessary to fuse the virus and the target cell.
