Description
Classical swine fever is a highly contagious, haemorrhagic disease of swine which is caused by a Togavirus. Presentation may be actue, sub-acute, chronic or persistent, and the disease is indistinguishable in the field from African Swine Fever. Acutely, classical swine fever is characterised by severe depression, high fever and superficial and internal haemorrhages, with many cases resulting in death. Depression, anorexia and pyrexia are seen in chronic classical swine fever. Transplacental infection is also possible and results in persistently infected piglets.

Control
- NOTIFIABLE disease
- Vaccination (live attenuated) in endemic countries:
- Parts of EU are using vaccinated bait to control spread in wild boar population
- Vaccination does not curtail spread: marker vaccine needed to distinguish virus exposure from vaccine-induced antibody
