Illustration of influenza (flu) virus particles (virions). In each particle's lipid envelope are two types of protein spike, haemagglutinin (H, orange) and neuraminidase (N, bright green). These determine the strain of virus and are used for recognising and binding to the host cell. At the virus' core is the RNA (ribonucleic acid) genetic material (not seen). | |
