One Health is an approach calling for "the collaborative efforts of multiple disciplines working locally, nationally, and globally, to attain optimal health for people, animals and our environment", as defined by the One Health Initiative Task Force (OHITF). It developed in response to evidence of the spreading of zoonotic diseases between species and increasing awareness of "the interdependence of human and animal health and ecological change". In this viewpoint, public health is no longer seen in purely human terms. A number of organizations throughout the world support the objectives of "One Health" including the One Health Commission (OHC), One Health Initiative, One Health Platform, The FAO-OIE-WHO collaboration, CDC One Health Office and others. History Calvin Schwabe, a veterinarian trained in public health, coined the term "One Medicine" in a veterinary medical textbook in 1964, to reflect the similarities between animal and human medicine and stress the importance of collaboration between veterinarians and physicians to help solve global health problems. He established a department at University of California, Davis to jointly address issues in the animal and human health sciences. In 2004, The Wildlife Conservation Society held a conference at Rockefeller University in New York called "One World, One Health". Out of that conference the twelve Manhattan Principles were created to describe a unified approach to the prevention of epidemic diseases. These principles emphasized links between humans, animals, and the environment; their importance in understanding disease dynamics; and the need for interdisciplinary approaches to prevention, education, investment, and policy development. Due to global scares surrounding the H5N1 influenza outbreaks of the early-mid 2000s, the American Veterinary Medical Association established a One Health Initiative Task Force in 2006, the American Medical Association passed a One Health resolution to promote partnering between veterinary and human medical organizations in 2007, and a One Health approach was recommended for responses to global disease outbreaks in 2007. Building on these initiatives, the Food and Agriculture Organization (FAO), World Organization for Animal Health (OIE), and World Health Organization (WHO) came together with the United Nations Children's Fund (UNICEF), United Nations System Influenza Coordination, and the World Bank to develop a framework entitled "Contributing to One World, One Health-A Strategic Framework for Reducing Risks of Infectious Diseases at the Animal-Human-Ecosystems Interface” in 2008, reiterating recommendations for a One Health approach to global health. This framework was expanded and implementable policies developed at Stone Mountain, Georgia in May 2010.
