Bovine Viral Diarrhoea Virus (BVDV) infections can have significant and serious implications to the milk and meat production industry. The presence of the virus can cause spontaneous abortions in cows or result in the transplacental spread of the virus to newborn calves, making them persistently infected (PI). Unidentified PI animals can remain in the herd and can spread the infection to other cattle. This can greatly endanger the success of a BVDV farm control or eradication program.

The course of BVDV infection depends on the state of the affected animal (immunity, gestation) as well as on the virus strain causing the infection. The classic, acute form of Bovine Viral Diarrhoea (BVD) includes symptoms such as diarrhoea, fever, anorexia, nasal and eye discharge and erosions in the oral cavity, on the muzzle, on the vaginal mucosa as well as in the interdigital cleft.
BVDV belongs to the genus Pestivirus of the family Flaviviridae. BVD has a world-wide distribution, and is characterized by high prevalence and relatively low morbidity. All age groups are susceptible.

There are no known risks to human health from this disease.

The BVD virus can have significant and serious implications to the milk and meat production industry. An outbreak of the virus can impact cattle herds in the following ways: fertility problems, spontaneous abortions, secondary infections, reduced feed intake and weight gain, and even animal deaths.

Prionics has developed a complete PI-animal detection system which combines traceability with early detection of BVDV and is supported by a fully integrated software solution. This unique system now enables easy, effective, and early removal of persistently infected animals from a herd.
