Animal HealthDiseasesPseudorabies


Pseudorabies (also known as Aujeszky’s disease) is a disease of swine that can also affect cattle, horses, dogs, cats, sheep, and goats. The disease is caused by pseudorabies virus (PRV), an extremely contagious herpesvirus that causes reproductive problems, including abortion, stillbirths, and even occasional death losses in breeding and finishing hogs.

The virus is not contagious to humans, not even to people working on farms with many PRV-infected animals.

ReportPseudorabies is a reportable animal disease. Report any confirmed or suspected case to: MT State Veterinarian 406-444-2043 and MT USDA APHIS Veterinary Services 406-449-2220.
