This Very Short Introduction outlines the nature of public health in our world today and places public health in its historical context from the earliest times, analysing in particular the changes in public health regulation through the nineteenth century and the twentieth and twenty first centuries.

As doctors and biologists have learned, to their dismay, infectious disease is a moving target: new diseases emerge every year, old diseases evolve into new forms, and ecological and socioeconomic upheavals change the transmission pathways by which disease spread. By taking an approach focused on the general evolutionary and ecological dynamics of disease, this Very Short Introduction provides a general conceptual framework for thinking about disease. Ecology and evolution provide the keys to answering the 'where', 'why', 'how', and 'what' questions about any particular infectious disease: where did it come from? How is it transmitted from one person to another, and why are some individuals more susceptible than others? What biochemical, ecological, and evolutionary strategies can be used to combat the disease? Is it more effective to block transmission at the population level, or to block infection at the individual level? Through a series of case studies, Benjamin Bolker and Marta L. Wayne introduce the major ideas of infectious disease in a clear and thoughtful way, emphasising the general principles of infection, the management of outbreaks, and the evolutionary and ecological approaches that are now central to much research about infectious disease.

Viruses are big news. From pandemics such as HIV, swine flu, and SARS, we are constantly being bombarded with information about new lethal infections. In this Very Short Introduction, Dorothy Crawford demonstrates from their discovery and the unravelling of their intricate structures, how clever these entities really are.

What is epidemiology? What are the causes of a new disease? How can pandemics be prevented? Epidemiology is the study of the changing patterns of disease and its main aim is to improve the health of populations. It's a vital field, central to the health of society, to the identification of causes of disease, and to their management and prevention. Epidemiology has had an impact on many areas of medicine; from discovering the relationship between tobacco smoking and lung cancer, to the origin and spread of new epidemics. However, it is often poorly understood, largely due to misrepresentations in the media. In this Very Short Introduction Rodolfo Saracci dispels some of the myths surrounding the study of epidemiology. He provides a general explanation of the principles behind clinical trials, and explains the nature of basic statistics concerning disease. He also looks at the ethical and political issues related to obtaining and using information concerning patients, and trials involving placebos.

'World music' emerged as an invention of the West from encounters with other cultures. This book draws readers into a remarkable range of these historical encounters, in which music had the power to evoke the exotic and to give voice to the voiceless. In the course of the volume's eight chapters the reader witnesses music's involvement in the modern world, but also the individual moments and particular histories that are crucial to an understanding of music's diversity. World Music is wide-ranging in its geographical scope, yet individual chapters provide in-depth treatments of selected music cultures and regional music histories. The book frequently zooms in on repertoires and musicians - such as Bob Marley, Bartok, and Nusrat Fateh Ali Khan - and attempts to account for world music's growing presence and popularity at the beginning of the twenty-first century.

Throughout history plague has been the cause of many major catastrophes. It was responsible for the Black Death of 1348 and the Great Plague of London in 1665, and for devastating epidemics much earlier and much later, in the Mediterranean in the sixth century, and in China and India between the 1890s and 1920s. Today, it has become a metaphor for other epidemic disasters which appear to threaten us, but plague itself has never been eradicated. In this Very Short Introduction, Paul Slack explores the historical impact of plague over the centuries, looking at the ways in which it has been interpreted, and the powerful images it has left behind in art and literature. Examining what plague meant for those who suffered from it, and how governments began to fight against it, he demonstrates the impact plague has had on modern notions of public health and how it has shaped our history.
