Is KHV a herpesvirus?
The work of Waltzek and colleagues (Waltzek et al. 2005, 2009) revealed that KHV is indeed a herpesvirus, based on virus morphology and genetics, and is closely related to carp pox virus ( Cyprinid herpesvirus 1; CyHV1) and goldfish hematopoietic necrosis virus ( Cyprinid herpesvirus 2; CyHV2).
What are the signs and symptoms of Kelvin KHV disease?
KHV infection may produce severe gill lesions which exhibit as gill mottling with red and white patches (Figure 1) (may be similar to columnaris disease signs; SRAC publication #479b on Columnaris Disease ). The white patches are due to necrosis (death) of the gill tissue.
Can KHV spread to other fish?
Survivors of KHV outbreaks may become carriers of the virus and may be capable of spreading the disease to susceptible fish. These carrier fish may not show signs of KHV infection although they may be carrying and/or shedding the virus. How does water temperature affect KHV disease?
