Although it was thought that this virus shows virulence only to
goldfish, Wang et al. (2012) reported that mass mortality
caused by CyHV-2 infection occurred in Prussian
carp Carassius gibelio in China. Furthermore, Daneˇk
et al. (2012) detected this virus from the same species
in the Czech Republic. These reports suggest that this
virus has been spreading by movement of diseased or
carrier fish and also that CyHV-2 has the potential to
infect other species of the genus Carassius.
