to further explore the possibility of transmission of CWD to other species. By April 2016, CWD had been found in captive animals in South Korea; the disease arrived there with live elk that were imported from Canada for farming in the late 1990s. In the summer of 2018, cases were discovered in the Harpur Farm herd in Grenville-sur-la-Rouge, Quebec. Over the course of 2018, 12% of the mule deer that were tested in Alberta, had a positive result. More than 8% of Alberta deer were deemed seropositive. In 2022, it had been recorded that outbreaks of CWD had shown themselves in both the United States and Canada. CWD was present in 29 states, infecting herds of moose, deer and elk in 391 different counties. Alabama (1), Arkansas (19), Colorado (27), Idaho (1), Illinois (19), Iowa (12), Kansas (49), Louisiana (1), Maryland (1), Michigan (9), Minnesota (7), Mississippi (9), Missouri (21), Montana (23), Nebraska (43), New Mexico (3), New York (1), North Carolina (1), North Dakota (7), Ohio (2), Pennsylvania (14), South Dakota (19), Tennessee (14), Texas (7), Utah (7), Virginia (10), West Virginia (5), Wisconsin (37) and Wyoming (22). Europe 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. In May and June 2016, two infected wild moose (Alces alces) were found around 300 km north from the first case, in Selbu. By the end of August, a fourth case had been confirmed in a wild reindeer shot in the same area as the first case in March. In 2017, the Environment Agency of the Norwegian government released guidelines for hunters hunting reindeer in the Nordfjella areas. The guidelines contain information on identifying animals with CWD symptoms and instructions for minimizing the risk of contamination, as well as a list of supplies given to
