Cyprinid herpesvirus包含carp pox virus (fish papilloma virus，Cyprinid herpesvirus 1; CyHV1)，goldfish hematopoietic necrosis virus (Cyprinid herpesvirus 2; CyHV2)和koi herpesvirus（Cyprinid herpesvirus 3; CyHV3）。
CyHV1：Superficial papilloma-like growths can occur over limited or extensive areas of the skin, but these are often most prominent on the fins.
CyHV2：An acute systemic disease in goldfish (Carassius auratus). Before death, affected fish may exhibit lethargy and focal pallor of the gills. Internal lesions include pallor of the kidney and spleen. Histologic lesions include severe ne...

CyHV1：Superficial papilloma-like growths can occur over limited or extensive areas of the skin, but these are often most prominent on the fins.
CyHV2：An acute systemic disease in goldfish (Carassius auratus). Before death, affected fish may exhibit lethargy and focal pallor of the gills. Internal lesions include pallor of the kidney and spleen. Histologic lesions include severe necrosis of the interstitial hemopoietic tissues in the kidney and spleen. Intranuclear inclusions within infected cells provide a presumptive diagnosis in affected goldfish populations.
CyHV3：KHV infection may produce severe gill lesions which exhibit as gill mottling with red and white patches (may be similar to columnaris disease signs). The white patches are due to necrosis (death) of the gill tissue. Gill lesions caused by KHV disease are the most common clinical signs in affected koi. Other external signs of KHV may include bleeding gills, sunken eyes, and pale patches on the skin. Some KHV infected koi may have a notched nose (Goodwin 2012).主要造成鰓的問題
