Incidence and control of CSF in wild boar in Europe.

The possibility that Classical swine fever (CSF) persists in a wild boar population has been shown in some areas of France, Germany and Italy in recent years. Availability of susceptible animals and frequency of infectious contacts are major variables influencing disease evolution. In the European Union (EU) measures to control CSF in the wild boar are enforced in the framework of Council Directive 80/217/EEC, including eradication plans that must be enforced taking account of the local epidemiological situation. Oral vaccination experiments are being carried out in Germany, which have not led to final conclusions concerning the efficacy of vaccination in eradicating disease.
