Technical Abstract: Due to the sheer number of different clinical presentations existing under the BVD umbrella, diagnosing BVD based on clinical signs is not advisable. Thus diagnosis relies upon testing of samples in diagnostic laboratories. In the US, most of the diagnostic effort has been focused on identifying and culling animals persistently infected with BVD pathogens. The Academy of Veterinary Consultants recommends that testing for animals persistently infected with a BVD pathogen be incorporated into both beef and dairy biosecurity plans. However, as case number one illustrates, outbreaks of acute BVD can result in substantial losses. Based on surveillance data it is estimated that 85% of cattle in the US have been exposed to a BVD pathogen and 10% of herds currently harbor a persistently infected animal. The question is not whether a practitioner will witness an outbreak of BVD, but when they will witness it. Their ability to recognize BVD when they see it depends on regularly including BVD as a differential in their case workups.
