Bovine Viral Diarrhea (BVD)

What is Bovine Viral Diarrhea (BVD)?
BVD is caused by a class of viruses called pestiviruses. They infects livestock and other ruminants such as llamas and deer.

Transmission of BVD: (reword ...)
The BVD virus typically enters an animal via the oral/nasal route, much like cold viruses in humans. Acute or persistently infected (PI) cattle shed the virus in mucus, saliva, feces, and urine. BVDV can also be transmitted, to a much lesser extent, by contaminated equipment, semen, fetal calf serum, and biting insects.

Symptoms of BVD:  
Seventy to ninety percent of all bovine viral diarrhea virus (BVDV) infections occur without the appearance of clinical signs. Common problems associated with the virus include diarrhea, general illness, abortion, oral ulcers, and immunosuppression.

Where is BVD found?
The BVD virus is found worldwide.
