A disease in carp that was associated with high mortality and that appeared to be of viral aetiology was first described in 1997 in Germany (Bretzinger et al, 1999), and from Israel and the USA in 1998 (Hedrick et al, 2000). There is evidence that CyHV-3 was actually present in carp in the UK in 1996 (Aoki et al, 2007). It has since spread to many other countries around the world.
The aetiological agent was considered to be a herpesvirus (Koi herpesvirus, KHV, now known as CyHV-3), and, in experimental infections, was associated with up to 100% mortality in both common carp (Cyprinus carpio carpio) and koi carp (C carpio koi). Furthermore, CyHV-3 affected fish of any age in either species (Hedrick et al, 2000). The disease is now considered to represent a significant threat to the important carp industry, not only in Eastern Europe (Haenen et al, 2004), but worldwide where the common carp is the world’s fourth most-farmed fish (Ronen et al, 2003).
