Founded in 1946 and composed of six members, the Scientific Commission for Animal Diseases (Scientific Commission) assists in identifying the most appropriate strategies and measures for disease prevention and control. It is also responsible for examining voluntary requests from WOAH Members regarding their disease-specific animal health status, if a Member wishes to be included in the WOAH official list of Members with a recognised diseases status for certain diseases (see WOAH ‘Disease-free’ status and ‘Disease-free’ recognition procedures). The Commission is elected by the World Assembly of Delegates for a three year term.
