Health systems everywhere are experiencing rapid change in response to new threats to health, including from lifestyle diseases, risks of pandemic flu, and the global effects of climate change but health inequalities continue to widen. Such developments have profound implications for the future direction of public health policy and practice.  The public health system in England offers a wide-ranging, provocative and accessible assessment of challenges confronting a public health system, exploring how its parameters have shifted and what the origins of dilemmas in public health practice are. The book will therefore appeal to public health professionals and students of health policy, potentially engaging them in political and social advocacy.
