municipalities. Adult hunter-harvested moose and slaughtered semi-domesticated reindeer from the area are tested for CWD. In September 2019, a third moose was found positive for CWD, a hunter-harvested 10-year-old apparently healthy female moose from Arjeplog. A fourth case of CWD in moose was verified in September 2020, in a euthanized 14-year-old lame and unshy female moose in the municipality of Robertsfors, in the county of Västerbotten, approximately 200 km from the previous moose cases in the neighboring county of Norrbotten. Research Research is focused on better ways to monitor disease in the wild, live animal diagnostic tests, developing vaccines, better ways to dispose of animals that died from the disease and to decontaminate the environment, where prions can persist in soils, and better ways to monitor the food supply. Deer harvesting and management issues are intertwined. References External links This entry incorporates public domain text originally at What is chronic wasting disease?
