Pseudorabies or Aujeszky's disease (Fr.: pseudorage) - signs and mode of transmission
Pseudorabies is a viral infection that can affect most mammals except humans. Pigs are the main reservoir of infection for the virus since this disease is always fatal for other susceptible species. The virus is transmitted by contact with infected animals, contaminated people or equipment as well as through the air. The severity of clinical signs may vary considerably. Among sows, it is displayed by fever, depression and abortions. Among piglets, it manifests itself as central nervous system problems (tremors, convulsions). Among feeder pigs, it causes an influenza-like illness (fever, depression, loss of appetite, respiratory problems, etc). Mortality is very high for young piglets. The disease may easily be confused with Porcine Reproductive and Respiratory Syndrome (PRRS). Vaccination is used for control or eradication in several countries. The last time Pseudorabies was diagnosed in Canada was in 1931. It is quite common throughout the world, including certain states of the United States.
