World Organization for Animal Health - OIE Human health and animal health are interdependent and bound to the health of the ecosystems in which they exist. This concept is envisaged and implemented by the OIE as a collaborative global approach to understanding risks for human and animal health (including both domestic animals and wildlife) and ecosystem health as a whole. The OIE builds upon the intergovernmental standards which it publishes and the worldwide information on animal health that it collects as well as its network of international experts and programmes for strengthening national Veterinary Services. Moreover, it collaborates synergistically with more than 70 other international organisations, particularly those which play a key role in the human–animal–ecosystems interface.
