Global Public Health: a new era is a comprehensive account of the international state of public health, including an agenda for improving the practice of the discipline across the world. It addresses three major issues, presented in distinct sections: the changing global context for publichealth; the state of public health theory and practice in both developed and developing countries; and strategies for strengthening the practice of public health in the twenty-first century. Part one surveys the complex old and new challenges facing public health practitioners, and then summarises the state of health globally using new data based on measures of the Global Burden of Disease developed by the Word Health Organization, and other groups, to better describe population healthstates and trends. Part two presents the first detailed review of the global state of public health. It analyses the public health situation in all regions of the world. Six chapters cover Europe, North and Latin America, and Australia and New Zealand, including a new chapter focusing on the UK. Three chapters coverChina, India, and Sub-Saharan Africa. The lessons from these chapters are surprisingly similar: the challenges are great; the public health workforce and infrastructure have long been neglected; and much needs to be done to reinvigorate the practice of public health. The third section covers several cross cutting themes, including the developing field of international public health ethics and the central and neglected role of the public in strengthening the practice of public health. The final chapter summarises the major themes of the book and explores theopportunities for building the capacity of the public health workforce to respond to the major global health needs. Despite the enormity of the challenges facing public health practitioners, especially in low and middle income countries, the tone adopted in the final section of this book isrelatively optimistic. The editors are convinced that a reinvigorated public health practice will contribute substantially to improving the global health situation, especially for the most disadvantaged populations, whether in poor or wealthy countries.
