Herpes viruses

Author: Dr Amanda Oakley, Dermatologist, Hamilton, New Zealand, 2013.

The human herpes viruses (HHV) include several very common viruses that have cutaneous manifestations. The Herpesvirales family is characterised by:

  • Double-stranded DNA genome
  • Icosahedral capsid surrounded by a tegument
  • Lipid envelope derived from infected cell membranes modified by insertion of viral-encoded glycoproteins
  • Diameter of 160–200 nm
  • Infectious, latent (persistence in the host) and reactive phases of infection
