The ways in which the great plagues of the past and present have spread around the world remains only partly understood. Peter Haggett's research over the last thirty years has focused on mapping and modelling the paths by which epidemics spread through human communities. In 1998 this led tohim being invited to give the inaugural lectures in a new series, the Clarendon Lectures in Geography and Environmental Studies. The resulting book, Geographical Structure of Epidemics, presents an accessible, concise, and well illustrated account of how environmental and geographical concepts canbe used to enhance our knowledge of the origins and progress of epidemics, and sometimes to slow to slow or halt their spread.
The last half century has witnessed two landmark events in medical history. The 1970s saw euphoria about the defeat of one of humankind's oldest disease scourges with the global eradication of smallpox. To set against this, the 2020s are experiencing the pandemic ravages of new viral diseases, of which COVID-19 is currently the most potent. But it is only the latest of a succession of threats. A Geography of Infection explores the distinctive spatial patterns and processes by which such infectious diseases spread from place to place and can grow from local and regional epidemics into global pandemics. This resource focuses initially on the local scale of doctors' practices and small islands where epidemic outbreaks are slight in the numbers infected and in geographical extent. Such local area studies raise two questions. First, how and where do epidemic diseases emerge and second, why do more diseases appear to be emerging now? To approach such questions implies a shift in spatial gear from painting epidemics with a fine-tipped local brush to an expanded palette on which doctors' practices and small islands are replaced by regional and global populations. Simultaneously, time bands are extended backwards to the origins of civilization and forwards into the twenty-first century. It eventually leads to a consideration of global pandemics - both historical (for example, plague, cholera and influenza) and contemporary (HIV/AIDS and COVID-19) and examines the ways the spread of infection can be prevented. All chapters are extensively illustrated with full-colour diagrams and maps - some of which are in colour for the first time. Bringing together the authors' collective 150 years of experience in research, mapping, and writing on spatial aspects of medical history, this is an invaluable resource for anyone interested in the spread, control, and eradication of epidemic and pandemic diseases.
Despite advances in modern medicine, the power of plagues to terrify, disrupt and bring huge swings in morbidity and mortality in their wake remains potent. A Geography of Infection explores the spatial mechanisms by which infectious diseases, such as measles and influenza, can develop into epidemics and pandemics.

The euphoria about the defeat of epidemics which surrounded the global eradication of smallpox in the 1970s proved short-lived. The advent of AIDS in the following decade, the widening spectrum of other newly-emergent diseases (from Ebola to Hanta virus), and the resurgence of old diseases such as tuberculosis and malaria all suggest that the threat of epidemic diseases remains at an historic high. The World Atlas of Epidemic Diseases provides a timely and scholarly review of over fifty of the most important such diseases at the start of the twenty-first century. This stunningly presented collection of maps, illustrations and commentary offers an authoritative overview of the global distribution of major epidemic diseases on a variety of spatial scales from the local to the global. The Atlas is arranged in an historical sequence, beginning with classic plagues such as the 'Black Death' and cholera and moving on through smallpox and measles to 'modern' diseases such as AIDS and Legionnaires' disease. Over 400 figures are incorporated, including 150 specially drawn maps supported by micrographs of the causative agents, photographs of the disease vectors, historical prints and graphs of changing incidence. The text for each disease includes discussion of its nature and epidemiological features, its origin (where known) and historical impacts, and its global status at the start of the twenty-first century. The book concludes with an informed look towards the future, assessing the probable impacts of major medical advances on life expectancy and the chances of success of programmes for the global eradication of diseases such as polio and measles. The World Atlas of Epidemic Diseases makes a major new contribution to our knowledge of the global burden of disease and is an informative and fascinating reference on the changing distributions of disease. It will be an invaluable resource for anyone interested in the spread, control and eradication of epidemic disease.
An exploration of the geography by which measles has repeatedly passed through a series of communities in Iceland during the 20th century. Demonstrates the general principles which underlie person-to-person spatial diffusion processes.
The 1918-19 influenza epidemic killed more than fifty million people worldwide. The SARS epidemic of 2002-3, by comparison, killed fewer than a thousand. The success in containing the spread of SARS was due largely to the rapid global response of public health authorities, which was aided by insights resulting from mathematical models. Models enabled authorities to better understand how the disease spread and to assess the relative effectiveness of different control strategies. In this book, Lisa Sattenspiel and Alun Lloyd provide a comprehensive introduction to mathematical models in epidemiology and show how they can be used to predict and control the geographic spread of major infectious diseases. Key concepts in infectious disease modeling are explained, readers are guided from simple mathematical models to more complex ones, and the strengths and weaknesses of these models are explored. The book highlights the breadth of techniques available to modelers today, such as population-based and individual-based models, and covers specific applications as well. Sattenspiel and Lloyd examine the powerful mathematical models that health authorities have developed to understand the spatial distribution and geographic spread of influenza, measles, foot-and-mouth disease, and SARS. Analytic methods geographers use to study human infectious diseases and the dynamics of epidemics are also discussed. A must-read for students, researchers, and practitioners, no other book provides such an accessible introduction to this exciting and fast-evolving field.
The last four decades of human history have seen the emergence of an unprecedented number of 'new' infectious diseases: the familiar roll call includes AIDS, Ebola, H5N1 influenza, hantavirus, hepatitis E, Lassa fever, legionnaires' and Lyme diseases, Marburg fever, Rift Valley fever, SARS, and West Nile. The outbreaks range in scale from global pandemics that have brought death and misery to millions, through to self-limiting outbreaks of mainly local impact. Some outbreaks have erupted explosively but have already faded away; some grumble along or continue to devastate as now persistent features in the medical lexicon; in others, a huge potential threat hangs uncertainly and worryingly in the air. Some outbreaks are merely local, others are worldwide. This book looks at the epidemiological and geographical conditions which underpin disease emergence. What are the processes which lead to emergence? Why now in human history? Where do such diseases emerge and how do they spread or fail to spread around the globe? What is the armoury of surveillance and control measures that may curb the impact of such diseases? But, uniquely, it sets these questions on the modern period of disease emergence in an historical context. First, it uses the historical record to set recent events against a much broader temporal canvas, finding emergence to be a constant theme in disease history rather than one confined to recent decades. It concludes that it is the quantitative pace of emergence, rather than its intrinsic nature, that separates the present period from earlier centuries. Second, it looks at the spatial and ecological setting of emergence, using hundreds of specially-drawn maps to chart the source areas of new diseases and the pathways of their spread. The book is divided into three main sections: Part 1 looks at early disease emergence, Part 2 at the processes of disease emergence, and Part 3 at the future for emergent diseases.

Not illustrated. 1903 edition. Excerpt: ... PLAGUE. General Characters and Etiology. Clinically plague occurs under three principal forms: --the bubonic, the pneumonic, and the septicaemic. Some observers have spoken of a fourth form, --the abdominal or enteric, but it is doubtful whether this form exists. The clinical varieties of the disease have been thought to depend upon the different modes of penetration of the bacillus into the tissues--the bubonic by its passage through the skin and its multiplication in a lymphatic gland; the pneumonic by its being inhaled and multiplying in the lungs; the abdominal (if such variety exist) by its entering the alimentary passages. There is, however, evidence which seems to point to the possibility that each variety of the disease may have a distinct and specific character, bubonic cases giving rise to fresh bubonic cases, and pneumonic cases to fresh pneumonic cases. The Indian Plague Commission is of opinion that this, rather than the accident of the mode of penetration of the bacilli into the tissues, determines the character of the attack. But the evidence on the point is conflicting. Each variety of the disease may become septicaemic before death by the passage of the bacilli into the blood-stream. In some instances the attack seems to be septicaemic from the beginning. A mild form of plague or bubonic fever, or even a condition of enlarged glands without fever, is often seen before and during a plague epidemic, and is known as pestis ambulans or pestis minor. History. The oldest known historical references to the occurrence of plague are probably contained in the early books of the Old Testament. The Biblical use of the word plague is, like its medieval use, more often than not, in the general sense of a pestilence or epidemic disease, .
