Chronic Wasting Disease

The Norwegian Veterinary Institute (NVI) surveillance chronic wasting disease (CWD) in the cervid populations.  

The programme include moose (Alcec alces), red deer (Cervus elaphus), roe deer (Capreolus capreolus), reindeer (Rangifer tarandus) and fallow deer (Dama dama).

The aim of the surveillance programme is to document the status of CWD in the cervid populations in Norway. 

2020

A total of 22,528 samples of wild, semi-domesticated and captive Norwegian cervids were analysed in 2020. From these, one moose (Alces alces) tested positive for CWD. It was euthanized in Bamble municipality in Southern Norway due to a broken leg. Further, a case in wild reindeer was detected for the first time in Hardangervidda wild reindeer management area, within Vinje municipality. The reindeer was harvested during regular hunt. Both animals were males, 13 and 8 years old respectively. Both animals were detected with disease characteristics as described for the respective species in previous reports, i.e. detection of PrPSc in lymphoid tissue from the reindeer and only in the brain for the moose. In addition, 1 reindeer from Svalbard and 35 wild muskoxen (Ovibos moschatus) from the Dovrefjell Mountains were tested and found negative for TSE.
