Piscine reovirus (PRV) in British Columbia Piscine reovirus has generated significant publicity in BC over the past 2.5 years. An American organization, the Pacific Northwest Fish Health Protection Committee, recently investigated the available information about PRV in Western North America and concluded, “The ubiquitous nature of piscine reovirus (PRV), its apparent long time presence in wild Pacific salmonid stocks and the lack of clear association with disease suggest the virus poses a low risk to wild species of Pacific salmonids.”20 The lead author on the resultant white paper, Dr. Ted Meyers, has a Ph.D. in fish histopathology, and he has been conducting histopathology on Alaska salmonids for about 30 years. The white paper also stated: 1. “The disease "heart and skeletal muscle inflammation" (HSMI) has not been reported in wild salmon populations in Norway or elsewhere and thus appears to only be a threat to farmed fish.” 2. “Surveys detected the presence of PRV genetic material in wild and cultured Chinook and coho salmon from Washington State, BC Canada, and Alaska, where years of surveillance have reported no presence of HSMI.” 3. “HSMI has not been reported in North America.” 4. “HSMI has not been reported in trout or Pacific salmon species.”
These conclusions are consistent with the data in the three peer-reviewed scientific publications that include analysis of samples from BC (Kibenge et al. 2013; Marty et al. 2014; Garver et al. 2015).
UPDATE:
Molecular testing of archived fish tissues in BC, Canada has shown that PRV was present in asymptomatic wild and farmed Pacific salmon since 1987 and may have been present as early as 1977 before Atlantic salmon were imported for aquaculture.

Most important - The presence of a virus does not equal the presence of a disease.
