One Health is a collaborative, multisectoral, and trans disciplinary approach – working at the local, regional, national, and global levels with the goal of achieving optimal health outcomes recognizing the interconnection between people, animals, plants, and their shared environment.¹ It mobilizes multiple sectors, disciplines, and communities at varying levels of society to work together so that new and better ideas are developed that address root causes and create long-term, sustainable solutions.² It is an approach which recognizes that the health of people is closely connected to the health of animals and our shared environment.¹ Although not new, it has been gaining importance in the recent years because many factors have changed interactions between people, animals, plants, and our environment.
One Health issues includes:

1. Zoonotic diseases
2. Antimicrobial resistance
3. Food safety and food security
4. Vector-borne diseases
5. Environmental contamination
6. Other health threats shared by people, animals, and the environment.

Globally, One Health is gaining recognition as an effective way to fight health issues at the human-animal-environment interface, including zoonotic diseases.1 The Food and Agriculture Organization of the United Nations (FAO), the World Organisation for Animal Health (OIE), the United Nations Environment Programme (UNEP) and the World Health Organization (WHO) are working together to mainstream One Health so that they are better prepared to prevent, predict, detect, and respond to global health threats and promote sustainable development.³
