The COVID-19 pandemic has demonstrated our fragility as a species. Humanity was attacked by a previously unknown virus that spread very rapidly, thanks to a speed of population mobility never before seen in human history. It succeeded in creating the complete upset of the global socio-economic system. Such an event gives us an important stimulus to re-evaluate health in the context of a circular system that encompasses humans and the environment in which we live. The key challenge we face is the discovery of novel paths to crisis resolution. Can we abandon the often cherished, but now rather obsolete, tendency to specialize in a restricted subject area? Can we re-discover the ability to become permeable to ideas that reach us from other disciplines and embrace a thinking-out-of-the-box approach? This book encourages the reader to consider this challenge via the telling of stories, both great and small. Stories that, although sometimes overlooked, have defined the course of our history and thus open the door to a new pathway of progress. In some ways, COVID-19 may have shown the direction nature expects us to take. Ilaria Capua suggests to us that, today more than ever, we are the responsible actors in the circle of life, guardians of our planet and defenders of its health. As one entity of circular nature.

One Health: Challenges for the 21st Century is a transdisciplinary approach to health, considering the interdependency of human, animal, and environmental health. This approach to health promotion and disease prevention calls for integrative and interdisciplinary cooperation. From zoonotic diseases to environmental degradation, this book introduces core concepts of the One Health approach by presenting focal key challenges. The objective of this book is not centered solely on epidemiologic interactions of infectious diseases but also on the environmental and ecological implications of current major threats. Written by international experts, the ten chapters provide a comprehensive approach consisting of core concepts, practical examples, and applications that align with key challenges to public health. Therefore, this book is a valuable resource for public health professionals, veterinarians, physicians, environmental researchers, policymakers, and other professionals who seek to understand the overarching complexities of health. Examines the interconnection between humans, animals and the environment and how those relationships impact prevention, early detection, containment, and response to public health risks Offers concise and comprehensive coverage of the One Health concept, application to key public health challenges, and current and future developments Presents insights from an interdisciplinary group of international experts, containing examples to illustrate One Health framework and issues

Emerging infectious diseases are often due to environmental disruption, which exposes microbes to a different niche that selects for new virulence traits and facilitates transmission between animals and humans. Thus, health of humans also depends upon health of animals and the environment – a concept called One Health. This book presents core concepts, compelling evidence, successful applications, and remaining challenges of One Health approaches to thwarting the threat of emerging infectious disease. Written by scientists working in the field, this book will provide a series of "stories" about how disruption of the environment and transmission from animal hosts is responsible for emerging human and animal diseases. Explains the concept of One Health and the history of the One Health paradigm shift. Traces the emergence of devastating new diseases in both animals and humans. Presents case histories of notable, new zoonoses, including West Nile virus, hantavirus, Lyme disease, SARS, and salmonella. Links several epidemic zoonoses with the environmental factors that promote them. Offers insight into the mechanisms of microbial evolution toward pathogenicity. Discusses the many causes behind the emergence of antibiotic resistance. Presents new technologies and approaches for public health disease surveillance. Offers political and bureaucratic strategies for promoting the global acceptance of One Health.

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.

The 2018 FAO-OIE-WHO (Tripartite) zoonoses guide, “Taking A Multisectoral, One Health Approach: A Tripartite Guide to Addressing Zoonotic Diseases in Countries” (2018 TZG) is being jointly developed to provide member countries with practical guidance on OH approaches to build national mechanisms for multisectoral coordination, communication, and collaboration to address zoonotic disease threats at the animal-human-environment interface. The 2018 TZG updates and expands on the guidance in the one previous jointly-developed, zoonoses-specific guidance document: the 2008 Tripartite “Zoonotic Diseases: A Guide to Establishing Collaboration between Animal and Human Health Sectors at the Country Level”, developed in WHO South-East Asia Region and Western Pacific Region. The 2018 TZG supports building by countries of the resilience and capacity to address emerging and endemic zoonotic diseases such as avian influenza, rabies, Ebola, and Rift Valley fever, as well as food-borne diseases and antimicrobial resistance, and to minimize their impacts on health, livelihoods, and economies. It additionally supports country efforts to implement WHO International Health Regulations (2005) and OIE international standards, to address gaps identified through external and internal health system evaluations, and to achieve targets of the Sustainable Development Goals. The 2018 TZG provides relevant country ministries and agencies with lessons learned and good practices identified from country-level experiences in taking OH approaches for preparedness, prevention, detection and response to zoonotic disease threats, and provides guidance on multisectoral communication, coordination, and collaboration. It informs on regional and country-level OH activities and relevant unisectoral and multisectoral tools available for countries to use.

One Planet, One Health provides a multidisciplinary reflection on the state of our planet, human and animal health, as well as the critical effects of climate change on the environment and on people. Climate change is already affecting many poor communities and traditional aid programs have achieved relatively small gains. Going beyond the narrow disciplinary lens and an exclusive focus on human health, a planetary health approach puts the ecosystem at the centre. The contributors to One Planet, One Health argue that maintaining and restoring ecosystem resilience should be a core priority, carried out in partnership with local communities. One Planet, One Health offers an integrated approach to improving the health of the planet and its inhabitants. With chapters on ethics, research and governance, as well as case studies of government and international aid-agency responses to illustrate successes and failures, the book aims to help scholars, governments and non-governmental organisations understand the benefits of focusing on the interdependence of human and animal health, food, water security and land care.
