Unified One Health definition adopted by WHO, FAO, OIE & ENEP
Joint Tripartite (FAO, OIE, WHO) and UNEP statement
The One Health definition developed by the One Health High Level Expert Panel states:
One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems. It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and inter-dependent. The approach mobilizes multiple sectors, disciplines and communities at varying levels of society to work together to foster well-being and tackle threats to health and ecosystems, while addressing the collective need for clean water, energy and air, safe and nutritious food, taking action on climate change, and contributing to sustainable development.
The Food and Agriculture Organization of the United Nations (FAO), the World Organisation for Animal Health (OIE), the United Nations Environment Programme (UNEP) and the World Health Organization (WHO) welcome this newly formed operational definition of One Health from their advisory panel, the One Health High Level Expert Panel (OHHLEP), whose members (including Marion Koopmans, coordinator of our One Health PACT project) represent a broad range of disciplines in science and policy-related sectors relevant to One Health from around the world. The four organizations are working together to mainstream One Health so that they are better prepared to prevent, predict, detect, and respond to global health threats and promote sustainable development.
