The term “One Health” represents a concept of the inextricable link between human, animal and environmental health.
This concept is not new. The interdependence of human and animal medicine was espoused as “One Medicine” by physician pathologists Virchow and Osler in the 19th century. The term currently has different meanings for different people.
In 2008, the One Health Initiative defined One Health as “the collaborative effort of multiple disciplines working locally, nationally and globally to attain optimal health for people, animals, and our environment.” The One Health Initiative initially supported by the American Medical Association and the American Veterinary Medical Association, now lists over 40 supporting organizations on its website.
“One World – One Health” was coined by the Wildlife Conservation Society and in 2004, The Manhattan Principles were the result of an interdisciplinary symposium addressing the relationships between human, domestic animal and wildlife health. The Manhattan Principles are 12 recommendations that focus on the prevention of zoonotic disease and the maintenance of biodiversity.
