Illustration of an influenza (flu) virus particle (virion) binding to a host cell. The haemagglutinin (H) protein spike in the viral lipid envelope is binding to a sialic acid receptor on a host cell. Binding to this receptor allows the virus to enter the cell. Once inside the cell it will use the cells' machinery to make more copies of itself. | |
