Cyprinid herpesvirus 1 (Carp pox herpesvirus, CyHV1)

Infects Cyprinus carpio (Common carp and Koi) but, unlike Cyprinid herpesvirus 3, does not usually kill infected fish. Symptoms include shiny, opaque white waxy lumps on the fins, skin and lips. Regarded as the oldest recognised fish virus disease, being described about 400 years ago (Smail and Munro 1989 in Crockford 2007). 

Cyprinid herpesvirus 2 (Goldfish haematopoietic necrosis virus, Goldfish herpesvirus, CyHV2)

Infects Carassius auratus (Goldfish). Prevalence in southern African uncertain but as Goldfish are a common aquarium fish in this region, presumably it does occur here.

Cyprinid herpesvirus 3 (Koi herpesvirus, CyHV3, KHV)

Infects Cyprinus carpio (Common carp and Koi), often causing mass mortality. An outbreak was recorded from South Africa from 2001 - 2003 (Haenen et al. 2004).
