Classical swine fever and avian influenza epidemics: lessons learned.

Experience with recent large-scale epidemics of Classical Swine Fever and Avian Influenza--among others in the Netherlands--have teached us several lessons that should prepare us better for future outbreaks. Among others, improving early detection of outbreaks--by using syndrome surveillance systems--is a key factor, in which farmers and veterinary practitioners have an imminent role. A major step in this respect is facilitation of the use of exclusion diagnostics without closing down the farm in clinical situations with non-specific clinical signs observed in sick animals. The hesitance of farmers and veterinary practitioners to report a suspect clinical situation on a livestock farm and how to facilitate that process is another major issue. Furthermore, the importance of communication between the field and the laboratory with respect to post mortem examination will be highlighted, and the need for outbreak simulation exercises with neighbouring countries in order to be better prepared, will be discussed.
