About Bovine Viral Diarrhoea Virus (BVDV)

Bovine viral diarrhoea virus (BVDV) suppresses a cow's immune system, making the animal susceptible to a host of other infections. That's why BVDV is one of the world's most costly bovine diseases, with losses of $15–$88 per head from reduced herd productivity, health and reproductive efficiency.1

Stopping BVDV requires detecting and removing the infection source: persistently infected (PI) cattle that continually expose other animals to disease.

Because PI cattle often look healthy, a sensitive, specific diagnostic test is essential. Mistakes can be costly: whether it's removing a valuable animal from production or allowing an infected calf to join the herd.

Determining herd status is the first step toward a BVDV-free herd. IDEXX has a complete portfolio of BVDV tests, including antibody- and antigen-detection ELISAs for laboratories and rapid SNAP® and point-of-care tests for veterinarians. The IDEXX BVDV PI X2 Test and the rapid IDEXX SNAP® BVDV Antigen Test are USDA-licensed.
