One Health Initiative

One Health recognizes that the health of people is connected to the health of animals and the environment. We are committed to using a One Health approach by working with physicians, veterinarians, environmental scientists, and many others to monitor and control public health threats and to learn about how diseases spread among people, animals, and the environment. One Health issues include zoonotic diseases, vector borne diseases, antibiotic resistance, food safety, environmental health, mental health, occupational health, and more.
