   classical swine fever (csf) or hog cholera (also sometimes called pig plague based on the german word schweinepest) is a highly contagious disease of pigs, wild boar, and collared peccaries. ==clinical signs== swine fever causes fever, skin lesions, convulsions and usually (particularly in young animals) death within 15 days. the signs are indistinguishable from those of african swine fever. ==epidemiology== the disease is endemic in much of asia, central and south america, and parts of europe and africa. it was believed to have been eradicated in the united kingdom by 1966 (according to the department for environment, food & rural affairs), but an outbreak occurred in east anglia in 2000. it was eradicated in the usa by 1978, according to the united states department of agriculture. other regions believed free of csf include australia, canada (1962), ireland, new zealand and scandinavia. ==virus== thumb|pinpoint hemorrhages on the kidneys are characteristic of classical swine fever the infectious agent responsible is a virus csfv (previously called hog cholera virus) of the genus pestivirus in the family flaviviridae.classical swine fever, the center for food security and public health / the institute for international cooperation in animal biologics, college of veterinary medicine, iowa state university, update september 2009.http://www.dpi.qld.gov.au/health/3945.html  csfv is closely related to the ruminant pestiviruses that cause bovine viral diarrhoea (bvdv) and border disease (bdv). the effect of different csfv strains varies widely, leading to a wide range of clinical signs. highly virulent strains correlate with acute, obvious disease and high mortality, including neurological signs and hemorrhages within the skin. less virulent strains can give rise to subacute or chronic infections that may escape detection, while still causing abortions and stillbirths. in these cases herds in high-risk areas are usually serologically tested on a thorough statistical basis. infected piglets born to infected but subclinical sows help maintain the disease within a population. other signs can include lethargy, fe
