Åkerstedt J, Norström M, Mørk T. The surveillance and control programme for bovine virus diarrhoea (BVD) in Norway 2012. Surveillance and control programmes for terrestrial and aquatic animals in Norway. Annual report 2012. Oslo: Norwegian Veterinary Institute 2013.

Bovine virus diarrhoea virus was not detected in any of the herds sampled in 2012.

The aim of the surveillance and control programme for BVD in 2012 was to document freedom from the infection in Norwegian livestock and to contribute to the maintenance of this favourable situation.

Bovine virus diarrhoea (BVD) is caused by bovine virus diarrhoea virus (BVDV) in the genus pestivirus. The virus is the cause of mucosal disease and hemorrhagic syndrome, but the economically most important manifestations of disease are related to infection in pregnant animals, resulting in embryonic death, abortion and congenital defects. Persistently infected calves may be born and serve as the main reservoir of infection to other animals. Bovine virus diarrhoea is a notifiable disease in Norway. 

An eradication programme, financed by the authorities and the industry, started December 1992. During the programme period, the number of herds with restrictions decreased from2,950 in1994 to none at the end of 2006. Details of the programme and a discussion of factors important for its success are given in the annual report for 2006. Since 2007, the aim of the programme has been surveillance and control.
