In 2016, the first case of CWD in Europe was from the Nordfjella wild reindeer herd in southern Norway. Scientists found the diseased female reindeer as it was dying, and routine CWD screening at necropsy was unexpectedly positive. The origin of CWD in Norway is unknown, whereas import of infected deer from Canada was the source of CWD cases in South Korea. Norway has strict legislation and rules not allowing importation of live animals and deer into the country. Norway has a scrapie surveillance program since 1997; while no reports of scrapie within the range of Nordfjella reindeer population have been identified, sheep are herded through that region and are a potential source of infection.
