Classical swine fever is a highly contagious, haemorrhagic disease of swine which is caused by a [[:Category:Pestiviruses|Pestivirus]] from the family [[:Category:Flaviviridae|Flaviviridae]]. Presentation may be acute, 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.
