Close to 100% of the Atlantic salmon collected following the escape of 253,000 Atlantic salmon from a farm in Puget Sound, Washington State, were infected with a strain of piscine orthoreovirus (PRV) that appears to have originated from Iceland. The PRV sequences from these farmed Atlantic salmon were very similar to PRV isolates from the hatchery in Iceland purported to be the origin of the Atlantic salmon used in commercial aquaculture in Washington State.
