Salmonid herpesvirus 2 (SalHV-2) is a species of virus in the genus Salmovirus, family Alloherpesviridae, and order Herpesvirales.[1]
The virus has been referred to as Oncorhynchus masou virus (OMV) after the disease caused by the virus was first referred to as Oncorhynchus masou virus disease (OMVD) in 1981.[2]
The virus was first isolated in the ovarian fluid of masu salmon (Oncorhynchus masou) in 1971 from a hatchery in Hokkaido, Japan.[3] In later studies, the virus has been found to be pathogenic and oncogenic to fish other than masu salmon, including coho salmon (O. kisutch), kokanee salmon (O. nerka), chum salmon (O. keta), and rainbow trout (O. mykiss), though the virus is still referred to by the species it was initially found to have infected.[4][5] Salmonid herpesvirus 2 primarily affects such salmonid fish, both wild and farmed, in Japan, though it has been observed in Kuwait. Significant economic loss was suffered by the rainbow trout industry in Japan due to the virus, as the resulting disease affected many marketable-sized fish in 1992.[6]
