Salmonid herpesvirus 3 (SalHV-3) is a species of virus in the genus Salmovirus, family Alloherpesviridae, and order Herpesvirales.[1]
The virus has been referred to as epizootic epitheliotrophic disease virus (EEDV) after the disease caused by the virus was first referred to as epizootic epitheliotrophic disease (EED) in 1989.[2]
Salmonid herpesvirus 3 affects lake trout (Salvelinus namaycush), resulting in several mass mortality events over the years.[2]
The virus was initially identified in 1988 when investigating the cause behind the mass mortalities of cultured juvenile lake trout within two hatcheries located in the Great Lakes region of the United States.[3] By the end of the 1980s, 15 million lake trout had died due to the virus in the Laurentian Great Lakes Basin.[4][5] Hatcheries removed the infected fish and heavily sanitized the contaminated areas in order to prevent further spread of the virus. However, a northern Michigan hatchery experienced two outbreaks in 2012 and 2017, resulting in the loss of approximately 100,000 lake trout, indicating that the threat of Salmonid herpesvirus 3 is still present, possibly due to infected wild lake trout being introduced to the hatcheries for breeding.[4]
