Pseudorabies is a contagious, infectious, and communicable viral disease that primarily affects swine. The pig is the only natural host, but it can also affect cattle, sheep, goats, cats, and dogs. It is particularly devastating to breeding sows and piglets.
In adult pigs, the disease causes abortion and stillbirths, respiratory problems, and occasionally death. In newborn pigs, it attacks the respiratory and central nervous systems, causing incoordination, sneezing, coughing, and death.
