Infectious salmon anaemia (ISA) is a finfish disease caused by the ISA virus, which belongs to a family of viruses called Orthomyxoviridae. There is no human health concern with this disease. Depending on the strain of virus, outbreaks of ISA can result in death rates up to 90 per cent in affected populations of finfish.
ISA is a reportable disease in Canada. This means that anyone who suspects ISA in finfish they own or work with is required by law to notify the CFIA.
The disease was first detected in the Atlantic area in 1996. It has been reported in New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland.
In 2012, a surveillance program for ISA was initiated in the Pacific Ocean watershed and the Pacific Ocean off British Columbia. To date, no cases of ISA have been confirmed in these areas.
