A review of the One Health concept and its application as a tool for policy-makers

The One Health concept represents the inseparability of human, animal, and environmental health through a unified view of health care. This article addressed the topic of public health policies from the One Health perspective, demonstrating its inclusion in various health agendas such as emerging and reemerging infectious diseases, basic sanitation, mental health, chronic non-communicable diseases, interpersonal violence, and food safety. The results showed that the application of the One Health concept to the development and implementation of policies is associated with a growing need to involve transdisciplinary teams for solving complex problems to improve communication and to ensure the relevance and acceptability of public policies, thus guaranteeing governance. According to the principle of efficiency, the government must be aware of the evolution of technical knowledge and should use the One Health approach to improve the efficacy of already existing systems. We, therefore, conducted this review to contextualize current knowledge in this topic which is becoming an essential tool for public health policy-makers and practitioners around the world promoting a reflection on the importance of multiprofessional articulation in the implementation of intersectoral public health policies.
