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. 

2024

A total of 10,932 samples of wild, semi-domesticated and captive Norwegian cervids were analysed in 2024. Of these, two moose (Alces alces) tested positive for CWD, old females culled in Nore and Uvdal, and Notodden municipalities. The cases detected had disease characteristics as described for the species in previous reports, i.e. PrPSc were only detected in brain tissue, and no prions were detected in lymphoid tissues with diagnostic tests. In the Nordic countries, CWD have shown sporadic appearance in moose and red deer, whilst in reindeer the disease has been contagious and with lymphoid detections in routine diagnostics.
