Book excerpt: This book is designed to be a practical study in infectious disease dynamics. The book offers an easy to follow implementation and analysis of mathematical epidemiology. The book focuses on recent case studies in order to explore various conceptual, mathematical, and statistical issues. The dynamics of infectious diseases shows a wide diversity of pattern. Some have locally persistent chains-of-transmission, others persist spatially in ‘consumer-resource metapopulations’. Some infections are prevalent among the young, some among the old and some are age-invariant. Temporally, some diseases have little variation in prevalence, some have predictable seasonal shifts and others exhibit violent epidemics that may be regular or irregular in their timing. Models and ‘models-with-data’ have proved invaluable for understanding and predicting this diversity, and thence help improve intervention and control. Using mathematical models to understand infectious disease dynamics has a very rich history in epidemiology. The field has seen broad expansions of theories as well as a surge in real-life application of mathematics to dynamics and control of infectious disease. The chapters of Epidemics: Models and Data using R have been organized in a reasonably logical way: Chapters 1-10 is a mix and match of models, data and statistics pertaining to local disease dynamics; Chapters 11-13 pertains to spatial and spatiotemporal dynamics; Chapter 14 highlights similarities between the dynamics of infectious disease and parasitoid-host dynamics; Finally, Chapters 15 and 16 overview additional statistical methodology useful in studies of infectious disease dynamics. This book can be used as a guide for working with data, models and ‘models-and-data’ to understand epidemics and infectious disease dynamics in space and time.

Available in PDF, EPUB and Kindle. Book excerpt: The past 25 years have seen a major paradigm shift in the field of violence prevention, from the assumption that violence is inevitable to the recognition that violence is preventable. Part of this shift has occurred in thinking about why violence occurs, and where intervention points might lie. In exploring the occurrence of violence, researchers have recognized the tendency for violent acts to cluster, to spread from place to place, and to mutate from one type to another. Furthermore, violent acts are often preceded or followed by other violent acts. In the field of public health, such a process has also been seen in the infectious disease model, in which an agent or vector initiates a specific biological pathway leading to symptoms of disease and infectivity. The agent transmits from individual to individual, and levels of the disease in the population above the baseline constitute an epidemic. Although violence does not have a readily observable biological agent as an initiator, it can follow similar epidemiological pathways. On April 30-May 1, 2012, the Institute of Medicine (IOM) Forum on Global Violence Prevention convened a workshop to explore the contagious nature of violence. Part of the Forum's mandate is to engage in multisectoral, multidirectional dialogue that explores crosscutting, evidence-based approaches to violence prevention, and the Forum has convened four workshops to this point exploring various elements of violence prevention. The workshops are designed to examine such approaches from multiple perspectives and at multiple levels of society. In particular, the workshop on the contagion of violence focused on exploring the epidemiology of the contagion, describing possible processes and mechanisms by which violence is transmitted, examining how contextual factors mitigate or exacerbate the issue. Contagion of Violence: Workshop Summary covers the major topics that arose during the 2-day workshop. It is organized by important elements of the infectious disease model so as to present the contagion of violence in a larger context and in a more compelling and comprehensive way.

Download or read book Understanding Epidemics written by John Brooke and published by Austin Macauley Publishers. This book was released on 2022-04-29 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains, in non-technical terms, the relationship between man and the many bacteria, viruses and other micro-organisms with whom he lives in the most intimate manner throughout his existence. It is explained that for the most part, this coexistence is beneficial, but that through evolution and natural selection, some bacteria, viruses and other micro-organisms may become aggressive to the host in which they live and that others may become aggressive as a result of mutation through other species. This aggressiveness manifests itself through the diseases which afflict man and all that is living. The cause and nature of those diseases which have been most devastating for human society and which have greatly influenced the course of history are portrayed in this book, as are the means by which the spread of infections may be controlled before they progress to become epidemics and pandemics.

Download or read book The Threat of Pandemic Influenza written by Institute of Medicine and published by National Academies Press. This book was released on 2005-04-09 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public health officials and organizations around the world remain on high alert because of increasing concerns about the prospect of an influenza pandemic, which many experts believe to be inevitable. Moreover, recent problems with the availability and strain-specificity of vaccine for annual flu epidemics in some countries and the rise of pandemic strains of avian flu in disparate geographic regions have alarmed experts about the world's ability to prevent or contain a human pandemic. The workshop summary, The Threat of Pandemic Influenza: Are We Ready? addresses these urgent concerns. The report describes what steps the United States and other countries have taken thus far to prepare for the next outbreak of "killer flu." It also looks at gaps in readiness, including hospitals' inability to absorb a surge of patients and many nations' incapacity to monitor and detect flu outbreaks. The report points to the need for international agreements to share flu vaccine and antiviral stockpiles to ensure that the 88 percent of nations that cannot manufacture or stockpile these products have access to them. It chronicles the toll of the H5N1 strain of avian flu currently circulating among poultry in many parts of Asia, which now accounts for the culling of millions of birds and the death of at least 50 persons. And it compares the costs of preparations with the costs of illness and death that could arise during an outbreak.

Download or read book Learning from SARS written by Institute of Medicine and published by National Academies Press. This book was released on 2004-04-26 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of severe acute respiratory syndrome (SARS) in late 2002 and 2003 challenged the global public health community to confront a novel epidemic that spread rapidly from its origins in southern China until it had reached more than 25 other countries within a matter of months. In addition to the number of patients infected with the SARS virus, the disease had profound economic and political repercussions in many of the affected regions. Recent reports of isolated new SARS cases and a fear that the disease could reemerge and spread have put public health officials on high alert for any indications of possible new outbreaks. This report examines the response to SARS by public health systems in individual countries, the biology of the SARS coronavirus and related coronaviruses in animals, the economic and political fallout of the SARS epidemic, quarantine law and other public health measures that apply to combating infectious diseases, and the role of international organizations and scientific cooperation in halting the spread of SARS. The report provides an illuminating survey of findings from the epidemic, along with an assessment of what might be needed in order to contain any future outbreaks of SARS or other emerging infections.

Download or read book Public Health Systems and Emerging Infections written by Institute of Medicine and published by National Academies Press. This book was released on 2000-06-08 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Forum on Emerging Infections was created in 1996 in response to a request from the Centers for Disease Control and Prevention and the National Institutes of Health. The goal of the forum is to provide structured opportunities for representatives from academia, industry, professional and interest groups, and government to examine and discuss scientific and policy issues that relate to research, prevention, detection, and management of emerging infectious diseases. A critical part of this mission has been the convening of a series of workshops. Public Health Systems and Emerging Infections summarizes the fourth in a series of five workshops. With a focus on our knowledge and understanding of the role of private and public health sectors in emerging infectious disease surveillance and response, the participants explored the effects of privatization of public health laboratories and the modernization of public health care. The issues discussed included epidemiological investigation, surveillance, communication, coordination, resource allocations, and economic support.

Download or read book Epidemic Disease and Human Understanding written by Charles De Paolo and published by McFarland. This book was released on 2006-02-10 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than three thousand years of recorded history, human beings have struggled to understand the epidemic--the rapid spread of a contagious disease throughout a human population. This book draws on an extensive list of primary texts to present a comprehensive history of epidemiological thought. The book is primarily concerned with the human experience of epidemic disease and the various ways this experience has been conceptualized and communicated. Part I examines ancient religious, mythological and philosophical paradigms used to comprehend and interpret epidemic disease. Following the ancient period, perceptions changed; epidemics were understood as natural phenomena rather than as instruments of divine purpose. This transition is covered in Part II and illuminated by historical documents, such as Thucydides' description of the plague of Athens. Systematic examination of biomedical phenomena, which began in the seventeenth century and developed into modern medicine, is the focus of Part III. Finally, Part IV considers the ways in which epidemic disease has been treated in various works of literature. The discussion includes eyewitness accounts as well as such popular works of fiction as Sinclair Lewis' Arrowsmith and Albert Camus' The Plague. In surveying human responses to endemic disease, the book draws connections between three sub-genres of epidemiological writing: the encyclopedia, the intellectual history, and the biographical collection.

Available in PDF, EPUB and Kindle. Book excerpt: POPULATION HEALTH SCIENCE formalizes an emerging discipline at the crossroads of social and medical sciences, demography, and economics--an emerging approach to population studies that represents a seismic shift in how traditional health sciences measure and observe health events. Bringing together theories and methods from diverse fields, this text provides grounding in the factors that shape population health. The overall approach is one of consequentialist science: designing creative studies that identify causal factors in health with multidisciplinary rigor. Distilled into nine foundational principles, this book guides readers through population science studies that strategically incorporate: · macrosocial factors · multilevel, lifecourse, and systems theories · prevention science fundamentals · return on investment · equity and efficiency Harnessing the power of scientific inquiry and codifying the knowledge base for a burgeoning field, POPULATION HEALTH SCIENCE arms readers with tools to shift the curve of population health.

Download or read book Ethical and Legal Considerations in Mitigating Pandemic Disease written by Institute of Medicine and published by National Academies Press. This book was released on 2007-07-08 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent public workshops and working group meetings, the Forum on Microbial Threats of the Institute of Medicine (IOM) has examined a variety of infectious disease outbreaks with pandemic potential, including those caused by influenza (IOM, 2005) and severe acute respiratory syndrome (SARS) (IOM, 2004). Particular attention has been paid to the potential pandemic threat posed by the H5N1 strain of avian influenza, which is now endemic in many Southeast Asian bird populations. Since 2003, the H5N1 subtype of avian influenza has caused 185 confirmed human deaths in 11 countries, including some cases of viral transmission from human to human (WHO, 2007). But as worrisome as these developments are, at least they are caused by known pathogens. The next pandemic could well be caused by the emergence of a microbe that is still unknown, much as happened in the 1980s with the emergence of the human immunodeficiency virus (HIV) and in 2003 with the appearance of the SARS coronavirus. Previous Forum meetings on pandemic disease have discussed the scientific and logistical challenges associated with pandemic disease recognition, identification, and response. Participants in these earlier meetings also recognized the difficulty of implementing disease control strategies effectively. Ethical and Legal Considerations in Mitigating Pandemic Disease: Workshop Summary as a factual summary of what occurred at the workshop.

Download or read book Understanding the HIV AIDS Epidemic in the United States written by Eric R. Wright and published by Springer. This book was released on 2018-06-07 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the HIV/AIDS epidemic in the United States using the concept of syndemics to contextualize the risk of both well-known, and a few lesser-known, subpopulations that experience disproportionately high rates of HIV and/or AIDS within the United States. Since discovery, HIV/AIDS has exposed a number of social, psychological, and biological aspects of disease transmission. The concept of “syndemics,” or “synergistically interacting epidemics” has emerged as a powerful framework for understanding both the epidemiological patterns and the myriad of problems associated with HIV/AIDS around the world and within the United States. The book considers the disparities in HIV/AIDS in relation to social aspects, risk behavior and critical illness comorbidities. It updates and enhances our understanding of the HIV/AIDS epidemic in the United States and contributes to the expanding literature on the role of syndemics in shaping the public’s health.​

Download or read book Flu written by Gina Kolata and published by Farrar, Straus and Giroux. This book was released on 2011-04-01 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Veteran journalist Gina Kolata's Flu: The Story of the Great Influenza Pandemic of 1918 and the Search for the Virus That Caused It presents a fascinating look at true story of the world's deadliest disease. In 1918, the Great Flu Epidemic felled the young and healthy virtually overnight. An estimated forty million people died as the epidemic raged. Children were left orphaned and families were devastated. As many American soldiers were killed by the 1918 flu as were killed in battle during World War I. And no area of the globe was safe. Eskimos living in remote outposts in the frozen tundra were sickened and killed by the flu in such numbers that entire villages were wiped out. Scientists have recently rediscovered shards of the flu virus frozen in Alaska and preserved in scraps of tissue in a government warehouse. Gina Kolata, an acclaimed reporter for The New York Times, unravels the mystery of this lethal virus with the high drama of a great adventure story. Delving into the history of the flu and previous epidemics, detailing the science and the latest understanding of this mortal disease, Kolata addresses the prospects for a great epidemic recurring, and, most important, what can be done to prevent it.

Download or read book Epidemics written by Sarah Dry and published by Routledge. This book was released on 2010-09-23 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent disease events such as SARS, H1N1 and avian influenza, and haemorrhagic fevers have focussed policy and public concern as never before on epidemics and so-called 'emerging infectious diseases'. Understanding and responding to these often unpredictable events have become major challenges for local, national and international bodies. All too often, responses can become restricted by implicit assumptions about who or what is to blame that may not capture the dynamics and uncertainties at play in the multi-scale interactions of people, animals and microbes. As a result, policies intended to forestall epidemics may fail, and may even further threaten health, livelihoods and human rights. The book takes a unique approach by focusing on how different policy-makers, scientists, and local populations construct alternative narratives-accounts of the causes and appropriate responses to outbreaks- about epidemics at the global, national and local level. The contrast between emergency-oriented, top-down responses to what are perceived as potentially global outbreaks and longer-term approaches to diseases, such as AIDS, which may now be considered endemic, is highlighted. Case studies-on avian influenza, SARS, obesity, H1N1 influenza, HIV/AIDS, tuberculosis, and haemorrhagic fevers-cover a broad historical, geographical and biological range. As this book explores, it is often the most vulnerable members of a population-the poor, the social excluded and the already ill-who are likely to suffer most from epidemic diseases. At the same time, they may be less likely to benefit from responses that may be designed from a global perspective that neglects social, ecological and political conditions on the ground. This book aims to bring the focus back to these marginal populations to reveal the often unintended consequences of current policy responses to epidemics. Important implications emerge - for how epidemics are thought about and represented; for how surveillance and response is designed; and for whose knowledge and perspectives should be included. Published in association with the Economic and Social Research Council (ESRC)

Download or read book The Geographical Structure of Epidemics written by Peter Haggett and published by Oxford University Press. This book was released on 2000 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
