Bovine viral diarrhoea (BVD) has once again been receiving a lot of attention recently. The implementation of a national control programme has been announced in the Netherlands. The BVD type 2 outbreaks in 2013 and in the first half of this year have shown that BVD still represents a real risk.
In America, BVD type 1 and type 2 are equally prevalent. In the EU, the prevalence of type 2 is less than 10 percent. Of type 2, subtype 2c is most common in Germany and was also the cause of the recent outbreaks in the Netherlands. Subtype 2a has also been detected in Germany. The most common form of the BVD virus in the EU is type 1b, followed by type 1d.
