For the Emergency Prevention System for Transboundary Animal and Plant Pests and Diseases (EMPRES), transboundary animal diseases (TADs) are defined as those diseases that are of significant economic, trade and food security importance for a considerable number of countries, that can easily spread from one country to another and reach epidemic pro- portions, and that require international cooperation for control and management, including exclusion. The World Organisation for Animal Health (OIE) Terrestrial Animal Health Code included ASF among its former List A diseases, which were defined as “communicable dis- eases which have the potential for serious and rapid spread, irrespective of national borders, which are of serious socio-economic or public health importance and which are of major importance in the international trade of animals and animal products”. This manual provides information on the nature of ASF and the principles and strategic options regarding prevention, detection, control and elimination of the disease. It provides guidelines on the formulation of overall national policy for control and eradication of a pos- sible incursion of the disease for individual countries threatened by ASF. The manual identi- fies the personnel, equipment and facilities needed in a national ASF contingency plan. It suggests an outline for the format and contents of a national ASF contingency plan, which should be modified to suit the needs and circumstances of individual countries. During the preparation of this manual, consideration was given to the provisions given in the current OIE Terrestrial Animal Health Code. It is suggested that the manual be used together with the FAO Manual on the preparation of national animal disease emergency preparedness plans, revised in 2008.
