Herpes virus. Illustration of a virus belonging to the Herpesvirus group. This group includes the viruses that cause chickenpox, shingles, glandular fever and cold sores. At the viral centre (green) is the icosahedral (20-sided) protein shell of the virus, the capsid. This encloses the coiled nucleoprotein (genetic material). The capsid is surrounded by a lipoprotein membrane, the envelope (white). The envelope is acquired on release from host cells and is partly made from the host cell membrane. It is studded with peplomers (projections, blue) which form an irregular surface fringe surrounding the virus.
