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 30,147 samples of wild, semi-domesticated and captive Norwegian cervids were analysed in 2019. From these, two moose (Alces alces) tested positive for CWD, one fallen stock (found dead) from the Sigdal municipality in Southern Norway and one hunter harvested from the Selbu municipality in Mid-Norway. Both of these were old females (12 and 20 years respectively) with characteristics similar to previous CWD cases in Norwegian moose [1], i.e. no detection of PrPres in lymphoid tissue. In addition, four reindeer from Svalbard and 37 wild muskoxen (Ovibos moschatus) from the Dovrefjell Mountains were tested and found negative for TSE.
