Find out why veterinarians play integral roles in the One Health movement.
One Health refers to two related ideas: First, it is the concept that humans, animals, and the world we live in are inextricably linked. Second, it refers to the collaborative effort of multiple disciplines working locally, nationally, and globally to attain optimal health for people, animals, and the environment.

The concept behind One Health has existed for centuries. But even today studies in the areas of human, animal, and environmental science are largely conducted independently, and obvious connections may be missed. As the human population continues to grow and our relationships with animals continue to evolve, understanding the interdependencies of people, animals, and the environment becomes even more critical to our collective health and safety.
