Pseudorabies Signs and Symptoms

A list of clinical signs the animal may or may not display.

The clinical signs of pseudorabies include:

• excessive salivation
• fever
• depression
• convulsions

Mortality is high, up to 80 percent or higher in pigs under three weeks of age and about two percent in adult swine. Pregnant gilts and sows infected with PRV suffer embryonic death, abortion and birth of macerated (softened and decomposed) fetuses and stillbirths. Lowered conception rate often is reported in the next several months following an outbreak of pseudorabies in a herd.
