The Geographical Structure of Epidemics


Book Description

Peter Haggett's research over the last thirty years has focused on mapping and modelling the paths by which epidemics spread through human communities. This led to his 1998 inaugural lectures for a new series, the Clarendon Lectures in Geography and Environmental Studies, the result of which is this book. In it, Haggett presents an accessible, concise, and well illustrated account of how environmental and geographical concepts can be used to enhance our knowledge of the origins and progress of epidemics, and sometimes to slow or even halt their spread.




Disease Maps


Book Description

In the seventeenth century, a map of the plague suggested a radical idea—that the disease was carried and spread by humans. In the nineteenth century, maps of cholera cases were used to prove its waterborne nature. More recently, maps charting the swine flu pandemic caused worldwide panic and sent shockwaves through the medical community. In Disease Maps, Tom Koch contends that to understand epidemics and their history we need to think about maps of varying scale, from the individual body to shared symptoms evidenced across cities, nations, and the world. Disease Maps begins with a brief review of epidemic mapping today and a detailed example of its power. Koch then traces the early history of medical cartography, including pandemics such as European plague and yellow fever, and the advancements in anatomy, printing, and world atlases that paved the way for their mapping. Moving on to the scourge of the nineteenth century—cholera—Koch considers the many choleras argued into existence by the maps of the day, including a new perspective on John Snow’s science and legacy. Finally, Koch addresses contemporary outbreaks such as AIDS, cancer, and H1N1, and reaches into the future, toward the coming epidemics. Ultimately, Disease Maps redefines conventional medical history with new surgical precision, revealing that only in maps do patterns emerge that allow disease theories to be proposed, hypotheses tested, and treatments advanced.




The Geographical Structure of Epidemics


Book Description

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.




War Epidemics


Book Description

Down the ages, war epidemics have decimated the fighting strength of armies, caused the suspension and cancellation of military operations, and have brought havoc to the civil populations of belligerent and non-belligerent states alike. This book examines the historical occurrence and geographical spread of infectious diseases in association with past wars. It addresses an intrinsically geographical question: how are the spatial dynamics of epidemics influenced by military operations and the directives of war? The term historical geography in the title indicates the authors' primary concern with qualitative analyses of archival source materials over a 150-year time period from 1850, and this is combined with quantitative analyses less frequently associated with historical studies. Written from the viewpoints of historical geography, epidemiology, and spatial analysis, this book examines in four parts the historical occurrence and geographical spread of infectious diseases in association with wars. Part I: War and Disease, surveys war-disease associations from early times to 1850. Part II: Temporal Trends studies time trends since 1850. Part III: A Regional Pattern of War Epidemics, examines grand themes in the war-disease complex. Part IV: Prospects, considers a series of war-related issues of epidemiological significance in the twenty-first century.




The Geographic Spread of Infectious Diseases


Book Description

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.




Pandemic Influenza Preparedness and Response


Book Description

This guidance is an update of WHO global influenza preparedness plan: the role of WHO and recommendations for national measures before and during pandemics, published March 2005 (WHO/CDS/CSR/GIP/2005.5).




Under the Weather


Book Description

Since the dawn of medical science, people have recognized connections between a change in the weather and the appearance of epidemic disease. With today's technology, some hope that it will be possible to build models for predicting the emergence and spread of many infectious diseases based on climate and weather forecasts. However, separating the effects of climate from other effects presents a tremendous scientific challenge. Can we use climate and weather forecasts to predict infectious disease outbreaks? Can the field of public health advance from "surveillance and response" to "prediction and prevention?" And perhaps the most important question of all: Can we predict how global warming will affect the emergence and transmission of infectious disease agents around the world? Under the Weather evaluates our current understanding of the linkages among climate, ecosystems, and infectious disease; it then goes a step further and outlines the research needed to improve our understanding of these linkages. The book also examines the potential for using climate forecasts and ecological observations to help predict infectious disease outbreaks, identifies the necessary components for an epidemic early warning system, and reviews lessons learned from the use of climate forecasts in other realms of human activity.




A Geography of Infection


Book Description

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.

Mathematical Structures of Epidemic Systems


Book Description

The dynamics of infectious diseases represents one of the oldest and ri- est areas of mathematical biology. From the classical work of Hamer (1906) and Ross (1911) to the spate of more modern developments associated with Anderson and May, Dietz, Hethcote, Castillo-Chavez and others, the subject has grown dramatically both in volume and in importance. Given the pace of development, the subject has become more and more di?use, and the need to provide a framework for organizing the diversity of mathematical approaches has become clear. Enzo Capasso, who has been a major contributor to the mathematical theory, has done that in the present volume, providing a system for organizing and analyzing a wide range of models, depending on the str- ture of the interaction matrix. The ?rst class, the quasi-monotone or positive feedback systems, can be analyzed e?ectively through the use of comparison theorems, that is the theory of order-preserving dynamical systems; the s- ond, the skew-symmetrizable systems, rely on Lyapunov methods. Capasso develops the general mathematical theory, and considers a broad range of - amples that can be treated within one or the other framework. In so doing, he has provided the ?rst steps towards the uni?cation of the subject, and made an invaluable contribution to the Lecture Notes in Biomathematics. Simon A.
