The situation of classical swine fever (CSF) in the wild boar population of
Europe is described, with special reference to the course of infection and
transmission of CSF virus (CSVF) a within the wild boar population and fro
m wild boar to domestic pigs. Susceptible young boars and wild sows infecte
d juring pregnancy play an important role in the perpetuation of CSF. Furth
ermore, the perpetuation is promoted by a high population density. Once CSF
V is detected in wild boar it is recommended to set up a defined infected a
rea, and a monitoring zone around the defined infected area. All wild boar
found dead or shot by hunters must be investigated. The trade of wild boar
meat, of live domestic pigs and fresh pork is restricted in this area. CSF
control in wild boar population, has to be focused on an intensive diagnosi
s of all dead and shot wild boar, hygiene measures to prevent spread of CSF
V by hunting and by transport of wild boar or wild boar meat, and the reduc
tion of population density, especially of young boars. The oral immunizatio
n using a live virus vaccine is described. This immunization procedure coul
d be a complementary tool in future CSF control.
