The herpes viruses are a proposed virus regulation since 2007 and since 2009 according to the decision of the ICTV . The differences in the genome structure and the phylogenetic relationship between the family Herpesviridae (from which the name of the order is derived) and two other genera separated from it, justify the new virus order. The genus Ictalurivirus has been classified in the new family Alloherpesviridae (herpes virus in fish ) and the genus Ostreavirus in the new family Malacoherpesviridae (a herpes virus species in oysters ). The old Herpesviridae family now only includes viruses in birds , mammals, and reptiles .

Systematics

The internal systematics of the herpes virus is as follows:

• Okay herpes viral
  • Family Herpesviridae
    • Subfamily Alphaherpesvirinae
      • Genus Iltovirus
      • Genus Mardivirus
      • Genus simplex virus
      • Genus Varicellovirus
    • Subfamily Betaherpesvirinae
      • Genus Cytomegalovirus
      • Genus Muromegalovirus
      • Genus Proboscivirus
      • Genus Roseolovirus
    • Subfamily Gammaherpesvirinae
      • Genus Lymphocryptovirus
      • Genus Macavirus
      • Genus Percavirus
      • Genus Rhadinovirus
  • Family Alloherpesviridae
    • • Genus Batrachovirus
      • Genus Cyprinivirus (with species Koi herpesvirus , en.Cyprinid herpesvirus 3 )
      • Genus Ictalurivirus
      • Genus Salmonivirus
  • Malacoherpesviridae family
    • • Genus Ostreavirus
      • Genus Aurivirus

Koonin et al. (2015) suggest the following genealogy of the herpes viruses :

Herpes viral	Malacoherpesviridae     Herpesviridae     Alloherpesviridae

The origins (ancestors) of the herpes virus suggest Koonin et al. (2015, 2019) in the Caudovirales (tailed dsDNA bacteriophages ). A proposal from October 2019 was therefore officially confirmed by the ICTV in March 2020 to place both orders in a new common area “Duplodnaviria”.
