What is One Health?

Humans, animals, and the environment are fundamentally linked, yet the strategies to address their health typically remain separate. One Health:

  • Is a collaborative and interdisciplinary approach to optimizing health for humans, animals, and the environment at the local, national, and global level.
  • Incorporates expertise from diverse fields (including human and veterinary medicine, environmental and biological sciences, engineering, public health, political science, urban planning, economics, sociology, epidemiology, and statistical modeling) to study and solve important zoonotic and environmentally-induced diseases, diseases shared by humans and other animals, and challenges at the intersection of humans, animals, and the environment.

The mission of Tufts CTSI’s signature program in One Health is to optimize the health of humans, animals, and the environment through an innovative and integrative, interdisciplinary approach to education, research, and practice.

Who is eligible?

The One Health Program offers consultations to help researchers identify relevant natural animal research models and matchmaking services to connect collaborators for One Health-related projects. This service is available to all investigators at all levels, at all Tufts CTSI partner institutions and across the CTSA Consortium.


Our goals are to understand and solve human, animal, and environmental health challenges using a One Health approach, and to establish Tufts as a leader in fostering productive One Health teams to optimize the health of all species and the environment. One Health goals also include:


A key goal of the Tufts One Health Committee is to catalyze innovative research, education, field experiences, and community engagement through a collaborative and interdisciplinary One Health approach. We work to understand the complex interactions between human, animals, and the environment.

Examples of One Health collaboration:

  • Zoonotic Diseases: certain viruses (rabies, West Nile), bacteria (Salmonella, Leptospirosis), and protozoa (Cryptosporidiosis, Toxoplasmosis) can be transmitted between animals and humans. Environmental changes can play a role in how likely this transmission is to happen. By working together in an interdisciplinary approach, physicians, veterinarians, public health officials, and other health professionals can more effectively prevent and respond to disease outbreaks.
  • Abandoned Buildings and Animal Health: faculty members from Urban and Environmental Policy and Planning and Cummings School of Veterinary Medicine are studying the role of abandoned buildings on the health of animals, and consequently the health of people and broader ecological systems.
  • Animals as Sentinels for Environmental Risks: Diagnosing lead poisoning in a dog may serve as a sentinel or warning for risk of lead poisoning in children that live in the same household or environment.
  • Animal Models for Human Cancer: Elizabeth McNiel, DVM, PhD, whose research bridges the Molecular Oncology Research Institute at Tufts Medical Center and the Cummings School of Veterinary Medicine, is studying the role of aluminum in vaccine-associated tumors in cats as a model for human cancer.
  • One Health Clubs: Students on the Grafton and Medford Tufts campuses organized clubs to collaborate on interdisciplinary One Health activities such as One Health Day. If you are interested in joining the Grafton club, join the e-list. To join the Medford club, contact Jennifer Allen.


Tufts is preparing One Health leaders across all schools and levels of the university, and empowering them to address medical and environmental problems at the local, national, and global level.

Educational opportunities in One Health:

Active Citizenship

We are building upon the Tufts tradition of active citizenship by maximizing opportunities and engaging students, faculty, and staff in a spectrum of One Health interests and initiatives. The field of human-animal interaction studies the many benefits of animals for people, from pet ownership in military-associated children to the positive impact of animal-assisted therapy.

Examples of One Health service activities:

  • Tufts Paws for People: a volunteer group that provides animal visitation to those in need.
  • Reading Assistance Dogs: reading aloud to dogs may improve children’s attitudes about reading.


Tufts is addressing medical and environmental problems by fostering research by interdisciplinary One Health teams.

Examples of One Health research:

  • Pets and people share many of the same health problems. Physicians and veterinarians can collaborate to develop better treatments for both of their patients.
  • Clinical trials in animals are an important stepping stone to translate basic science research into human clinical trials. Animals and humans frequently suffer from similar diseases and chronic conditions such as cancer, heart disease, diabetes, and obesity. Clinical trials to evaluate innovative new drugs or treatments can benefit both animals and humans.
  • Natural animal models to study human disease and treatment can bridge bench and clinical research, reduce translational failures, and improve scientific discovery and application to benefit human health. WGBH reported on these efforts in 2014.
  • Studying the benefits of pets for children and young adults.

We are working to develop evidence-based solutions for One Health problems that can be broadly disseminated and implemented on local, national, global levels.
