Infectious salmon anemia virus spread from Norway to Chile

The Chilean salmon farming industry has been severely affected by disease caused by infectious salmon anemia virus. Salmon eggs shipped from Norway to Chile in 2007 are the cause of the outbreak (New York Times):

A virus that has killed millions of salmon in Chile and ravaged the fish farming industry there was probably brought over from Norway, a major salmon producer has acknowledged.

Infection salmon anemia virus is a member of the orthomyxovirus family, which also includes influenza virus. The virus causes disease in Atlantic salmon and has caused economic losses on fish farms in Canada, Norway, Scotland and Chile. We discussed the virus on This Week in Virology #41: Fish flu.
