One Health

Last Modified: October 11, 2024

"One Health" is an integrated, unifying approach that sustainably balances and optimizes the health of people, plants, domestic and wild animals, and ecosystems.

The One Health approach recognizes that:

the health of animals, people, plants, and the environment are linked, and
all those involved in protecting animal, human, and environmental health must work together to achieve the best health outcomes.

Our Partners

We partner with Federal agencies, States, Territories, Tribes, universities, organizations, and others—here at home and around the world—across multiple disciplines and sectors. Our goal is to find the best health outcomes for animals, plants, people, and their shared environment. View some of our partnerships.

Priority Issues

Protecting animal and plant health intersects with some of the most pressing issues of our time: climate change, diseases that can spread between animals and people, global population growth, and food security. One Health is key in finding solutions. Learn how we're advancing One Health practice through research, applied science, and other initiatives.
