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. 


A total of 21,661 samples of wild, semi-domesticated and captive Norwegian cervids were analysed in 2021. From these, two moose (Alces alces) and one red deer (Cervus elaphus) tested positive for CWD. The cases in moose were a female moose from fallen stock, 17 years old, found dead in Vinje municipality and a 13 years old male moose euthanized in the municipality of Bamble due to a broken leg. The red deer was a hunted animal, adult female, from the municipality of Etne. All locations are in Southern Norway. The cases detected had disease characteristics as described for the respective species in previous reports, i.e. PrPSc were only detected in brain tissue, and no prions were detected in lymphoid tissues with diagnostic test.
