Classical swine fever: the global situation

A historical and current perspective is given of classical swine fever and its impact on pig production in different regions of the world. Data were obtained from a variety of sources including returns to the Office International des Epizooties, official government reports, other published material and local information through personal contacts. The disease has been recognized for about 170 years and efforts to control it by official intervention began in the nineteenth century. Despite this it remains a lingering problem in many parts of the world where it has both, an economic impact on swine production and a constraining effect on trade due to the measures necessary to prevent spread.
