The epidemiology of Classical Swine Fever in the wild boar populations of Europe.

摘要: Abstract The paper summarizes the main features of Classical Swine Fever in wild boar Europe. Three outbreak models have been observed: small isolated populations, large populations sparse huge forested areas, sympatric boars and domestic back yard pigs often free ranging. mechanisms outcomes three different explained discussed. risk factors for introduction further spread virus a population highlighted. epidemiological parameters (β, R 0 , Nt, CCS) four selected European outbreaks estimated, described compared with available literature. Finally strategies control are discussed light experienced gained Union. Introduction relevance classical swine fever (CSF) Europe becomes apparent after eradication infection pig EU. During late 70’s early 80’s sole reservoir was while few cases registered were mainly spill over animals (Laddomada, 2000). At beginning 80’s, particular Germany Italy an increasing number registered.
