“One Health has been part of the veterinary vocabulary for some time. Perhaps more than any other profession, veterinarians understand that the health of animals, people and the environment are intrinsically connected. Here at OVC, the One Health concept is woven into all that we do – teaching, research and outreach.” -OVC Dean, Dr. Jeff Wichtel

The interrelationship between the health of humans, animals, and the environment has been recognized for decades.  However, in this time of emerging zoonoses and other health crises, there is an increasing recognition that the One Health agenda needs to move beyond the conceptual and become an operational component of the health portfolio, both nationally and globally.

Zoonotic diseases – Lyme disease, Zika virus, rabies – are increasingly being portrayed in the media as One Health issues; discussions around food safety and food security are taking on increased urgency in the media, and the environmental health of the planet dominates conversation. It seems that, after years of little progress, the One Health approach is gaining traction.

Conceptually, the One Health principle recognizes that the health of humans, animals, and the environment are directly linked; the health of each is dependent on the health of the others.  Our members have considerable expertise in One Health. Some of our researchers use a one health approach to their research, employing multidisciplinary research approaches to address a public health issue across the human-animal-environmental continuum. Other researchers work on a particular issue, or with a specific population, to address a one health topic.

The mandate of the Centre for Public Health and Zoonoses does not entirely encompass the topics that can be considered One Health issues, and all the same One Health does not cover everything related to public health and zoonotic disease. They are different ideas that interlink and we epitomize aspects of these connections and the strength our members display in these areas. Read on for more examples of One Health from our members.

November 3rd, 2017 will be One Health Day – Watch for event announcements soon!
