While many terms relate to One Health, the idea remains the same: to think outside a chosen area of specialty and work collaboratively as part of a team to improve health status around the world.This involves the collective effort of physicians, veterinarians, public health practitioners, ecologists, anthropologists, social workers, economists, and many others.Collectively, these are the Global One Health practitioners. Through the lens of infectious disease, this book brings together the diverse range of topics necessary to be an effective global health practitioner at the intersection of human and animal health, particularly in developing countries.It explores what an aspiring or mid-career practitioner should be aware of when working with infectious diseases, including technical skills, cultural competency, capacity building, big data, and understanding the landscape and history of global health.Each chapter focuses on a specific area of necessary knowledge with background information, case examples, and resources to use moving forward. An important reference for upper-level undergraduate students, graduate students, and early practitioners in human, animal, and public health, this text highlights the competencies rather than focusing on the problems in Global One Health.It provides a blueprint of areas that the reader should pay attention to, particularly in the realm of infectious diseases.
