Salmonid alphaviruses (SAVs), which include the etiological agents of salmon pancreas disease (PD) and sleeping disease (SD), are significant viral pathogens of European salmonid aquaculture, resulting in substantial economic losses to the salmonid-farming industry. Even though many countries including China have not reported the presence of SAV infections, these countries may be seriously threatened by these diseases as the salmon fish import trade increases. Thus, it is indeed necessary to develop efficient detection methods for the diagnosis and prevention of SAV infection...
