Aujeszky Disease Virus, also known as pseudorabies virus (PRV), is a contagious and fatal viral disease that primarily affects pigs but can also infect other animals, such as dogs, cats, cattle, sheep, and wild boars. It is caused by the Aujeszky Disease Virus belonging to the Herpesviridae family.
This disease is characterized by severe neurological symptoms, respiratory distress, and reproductive problems. It is primarily transmitted through direct contact with infected animals or ingestion of contaminated materials, such as feed or water. The virus can also spread through inhalation of aerosolized respiratory secretions. Infected pigs excrete the virus through saliva, nasal secretions, urine, and feces, contributing to its high contagiousness and rapid transmission.
Infection in domestic pigs usually leads to high mortality rates, especially in piglets. Symptoms may vary depending on the species affected, but commonly include fever, loss of appetite, depression, convulsions, and increased salivation.
There are no specific treatments available for Aujeszky Disease Virus, and control measures mostly focus on preventing its spread. Vaccination of susceptible animals, strict biosecurity measures, and rapid identification and culling of infected animals are important strategies for disease management.
Aujeszky Disease Virus poses a significant economic threat to the swine industry due to its impact on pig health and reproduction. Consequently, monitoring and surveillance programs are essential in preventing potential outbreaks and ensuring the safety of the livestock population.
