Content: This disease is notifiable – contact your vet and local authorities if you believe this disease is affecting your herd. Background and history
CSF is one of the most economically-damaging pandemic viral diseases of pigs in the world. Many governments take it very seriously and adopt strict control policies, which include compulsory vaccination or slaughter and eradication policies. In a susceptible (unvaccinated) herd almost all the pigs are affected. It causes generalised disease, including fever, malaise, lack of appetite, diarrhoea, paralysis, abortion, mummification and the birth of shaking piglets. Mortality is high. Fortunately, there is only one serotype of the virus and attenuated vaccines are highly effective. Also, it does not spread on the wind or on insects or birds so standard precautions of farm biosecurity should keep it out. However it persists in uncooked and cured meat and these should not be fed to pigs. Clinical signs
The virus that causes CSF varies in virulence.
