Bovine virus diarrhoea in cattle

Norway is regarded as free from bovine virus diarrhoea.

The aim of the national surveillance and control programme for bovine virus diarrhoea (BVD) is to document freedom from the infection in the Norwegian cattle population and to contribute to the maintenance of this favourable situation.

Background

Bovine virus diarrhoea 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 (list B) 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 from 2,950 in 1994 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 aims of the programme have been surveillance and control.

2022

Bovine viral diarrhoea virus was not detected in any of the herds sampled in 2022.
