What is One Health?

One Health is a collaborative effort of multiple disciplines working locally, nationally and globally to improve the health of our ecosystem, including humans, animals and our environment. One Health promotes multi-sectoral and cross-disciplinary collaboration to solve health challenges.

How is Department of Health Involved?

One Health requires relationship-building, communication, collaboration, and coordination among professionals in multiple sectors. Several offices and programs at the Department of Health use a One Health approach, including Communicable Disease Epidemiology, Environmental Public Health Sciences, and the Climate and Health program.

DOH is one of the coordinating agencies for the One Health Collaborative (below). In addition, DOH worked with the Governor's Office for recognition of One Health Day, on November 3rd, to raise awareness about the necessity of an interdisciplinary approach to solving health challenges.

Membership includes experts in human, animal, and environmental health. A key project is to develop a state plan for One Health antibiotic stewardship and AMR surveillance. Another project is to perform integrated surveillance of AMR in humans, animals, and environmental samples to provide data for decision making by clinicians and health officials.

Surveillance and Data Systems Workgroup

The goal of this group is to integrate and share data regarding diseases crossing between humans, animals, and the environment to enhance disease surveillance and prevention. An example is the increased sharing of reportable disease data between animal health and human health surveillance efforts, and to compare environmental risk data to disease reports.
