It is also responsible for examining voluntary requests from WOAH Members regarding their disease-specific animal health status.

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.

    Animal Health and Welfare

    Like human health, animal health is complex and is faced with ever-evolving challenges. Thanks to the advances in technology, medicine and science, innovative solutions can be used to address animal diseases threats, whether they affect terrestrial animals, aquatic animals or wildlife. Animal health is a key component of animal welfare. Animal health professionals are the key actors in charge of optimising the physical and behavioural health and welfare of animals. They contribute to prevent, treat and control diseases which can affect an individual animal or even whole animal populations.
  • Determining disease status

    Official Disease Status

    Since 1998, the World Organisation for Animal Health has the mandate from the WTO to officially recognise disease-free areas of countries for trade purposes. The procedure for the official recognition of animal health status by WOAH is voluntary and applies currently to six diseases
