One Health

Six out of 10 infectious diseases in humans are spread from animals, and numerous others are shared.

Population growth, climate change, land conversion, international travel and other factors put people in closer contact with animals while upending natural processes that can control disease spread.

One Health examines the deep connections between the health of humans and animals, as well as their shared environment. Through an interdisciplinary approach that crosses boundaries, physicians, veterinarians, ecologists and other experts study the way diseases spread in order to control and prevent public health threats.

One Health at Stanford

Stanford’s focus on collaborative, interdisciplinary solution-oriented research and its expertise in environmental sciences and health make it an ideal proving ground for the discipline. Stanford departments, centers and programs such as the Department of Comparative Medicine, the Woods Institute for the Environment, the Center for Innovation in Global Health; and the Program for Disease Ecology, Health and the Environment, support a community of scholars that pioneers cutting-edge research and creative educational initiatives to affect policy and practice around challenges at the intersection of human and animal health. The annual Stanford One Health Symposium attracts some of the field’s leading scholars.

One Health in the Field

Stanford researchers are collaborating on numerous One Health initiatives around the world. Some examples:

Pigs, Parasites and Pupils

Medical researchers are looking at ways to curb dangerous tapeworm infections among school-age children in China.


Mosquito Tracking

An effort to understand how mosquitoes and humans interact in order to predict and prevent outbreaks of diseases such as Dengue, Zika and chikungunya.


Averting Pandemic


Stanford scientists are working to prevent transmission of a deadly virus from bats to people.
