Carp Pox Is A Common Herpes Virus Infection In Ornamental Koi

Carp pox is a common infection in ornamental koi. It is characterized by thickened epithelial growths along the dorsal ridge, sides, and fins of koi fish. It's a benign disease that only causes aesthetic changes. Severe outbreaks can result in secondary skin infections but are very rare. Clinical signs of Carp Pox herpes virus are more commonly seen in cool water temperatures. The signs will likely return when the water cools seasonally. This does not mean the virus is gone. It means the clinical signs are not present. Carp pox can be infected very young in life. It may not show clinical signs until years later. Secondary stress can activate latent infections and cause skin lesions. Goldfish will not show the symptoms of KHV when they are carriers. Like all other herpes viruses, latent virions will bury deep into neural tissue. This makes them impossible to remove or treat. Surgical removal of the plaques is not recommended since they will only grow back. You may lessen the pain of having to deal with pox by raising your water temperature. CarP pox virus is not known to be transmitted to other fish. Other cyprinid Herpes viruses are transmitted by other fish such as goldfish. . . .
