One Health: The Theory and Practice of Integrated Health Approaches (eng)

One Health, the concept of combined veterinary and human health, has now expanded beyond emerging infectious diseases and zoonoses to incorporate a wider suite of health issues. Retaining its interdisciplinary focus which combines theory with practice, this new edition illustrates the contribution of One Health collaborations to real-world issues such as sanitation, economics, food security and vaccination programmes. It includes more non-infectious disease issues and climate change discussion alongside revised case studies and expanded methodology chapters to draw out implications for practice. Promoting an action-based, solutions-oriented approach, One Health: The Theory and Practice of Integrated Health Approaches highlights the lessons learned for both human and animal health professionals and students.

Prof. Dr. Jakob Zinsstag is a veterinarian with a PhD in tropical animal health.

He spent eight years in West Africa at the International Trypanotolerance Centre in The Gambia and four years as the director of the Centre Suisse de Recherches Scientifiques in Côte d'Ivoire.

Esther Schelling is the Head of Innovations, Learning and Quality Assurance at Vétérinaires sans Frontières Suisse (VSF-Suisse). After more than 20 years of research on health of pastoralists, zoonoses and One Health approaches at the Swiss Tropical and Public Health Institute, she wanted to foster implementation of gained main lessons. She is co-editor of the textbook 'One Health: The theory and practice of integrated health approaches' (2015/2020). The added value of a closer cooperation between the health sectors are seen in the earlier recognition of health events, in better control of zoonosis and more efficient surveillance and integrated health services - but should be shown more explicitly. The OH4 HEAL project led by VSF-Suisse seeks to improve integrated health services for families, their livestock, and the environment they live in pastoral cross-border regions of Ethiopia, Kenya and Somali.
