ENTRY

• Naked viruses can deliver their genomes directly in to the cell through a pore in plasma membrane. Many naked viruses enter through endocytosis.
• The plasma membrane flows around the virus. More receptors bind and eventually the virion is completely enclosed in the membrane which pinches off as an endosome.
• In the case of enveloped viruses entry is by fusion of the viral envelope with plasma membrane or endocytosis followed by fusion of virus envelope with the endosome membrane.
