Food-borne Viruses


Book Description

Food-borne viruses are recognized as a major health concern, but their distribution, definition, and impact are poorly understood. The volume Food-Borne Viruses goes a long way in correcting that problem. Written by leading scientists in the field, it brings together the latest knowledge on these viral strains, their detection and control, and associated challenges.




Sustaining Global Surveillance and Response to Emerging Zoonotic Diseases


Book Description

H1N1 ("swine flu"), SARS, mad cow disease, and HIV/AIDS are a few examples of zoonotic diseases-diseases transmitted between humans and animals. Zoonotic diseases are a growing concern given multiple factors: their often novel and unpredictable nature, their ability to emerge anywhere and spread rapidly around the globe, and their major economic toll on several disparate industries. Infectious disease surveillance systems are used to detect this threat to human and animal health. By systematically collecting data on the occurrence of infectious diseases in humans and animals, investigators can track the spread of disease and provide an early warning to human and animal health officials, nationally and internationally, for follow-up and response. Unfortunately, and for many reasons, current disease surveillance has been ineffective or untimely in alerting officials to emerging zoonotic diseases. Sustaining Global Surveillance and Response to Emerging Zoonotic Diseases assesses some of the disease surveillance systems around the world, and recommends ways to improve early detection and response. The book presents solutions for improved coordination between human and animal health sectors, and among governments and international organizations. Parties seeking to improve the detection and response to zoonotic diseases-including U.S. government and international health policy makers, researchers, epidemiologists, human health clinicians, and veterinarians-can use this book to help curtail the threat zoonotic diseases pose to economies, societies, and health.




The Emergence of Zoonotic Diseases


Book Description

Zoonotic diseases represent one of the leading causes of illness and death from infectious disease. Defined by the World Health Organization, zoonoses are "those diseases and infections that are naturally transmitted between vertebrate animals and man with or without an arthropod intermediate." Worldwide, zoonotic diseases have a negative impact on commerce, travel, and economies. In most developing countries, zoonotic diseases are among those diseases that contribute significantly to an already overly burdened public health system. In industrialized nations, zoonotic diseases are of particular concern for at-risk groups such as the elderly, children, childbearing women, and immunocompromised individuals. The Emergence of Zoonotic Diseases: Understanding the Impact on Animal and Human Health, covers a range of topics, which include: an evaluation of the relative importance of zoonotic diseases against the overall backdrop of emerging infections; research findings related to the current state of our understanding of zoonotic diseases; surveillance and response strategies to detect, prevent, and mitigate the impact of zoonotic diseases on human health; and information about ongoing programs and actions being taken to identify the most important needs in this vital area.




Improving Food Safety Through a One Health Approach


Book Description

Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.




Viral Zoonoses and Food of Animal Origin


Book Description

Since the central theme of this book is the transmission of disease agents through the food chain, we will examine influenza viruses from this perspective. Influenza A viruses are found in humans, pigs, horses, sea mammals, and also in wild aquatic and domestic birds [23]. How are they spread? Between mammals, influenza is an airborne infection, but between birds, influenza can be either an airborne or waterborne infection. Influenza viruses of aquatic birds periodically transmit to domestic birds sometimes with catastrophic effects; this transmis sion can be either airborne or waterborne. Less frequently, avian influenza viruses transmit to mammals and three to four times in the past century this transmission has initiated a pandemic of influenza in humans. The method of spread of avian influenza viruses to mammals remains unresolved, but could be either airborne or waterborne. In this report we will consider recent examples of interspecies transmission of influenza A viruses and the possible prevention of emergence of the next human pandemic which is considered imminent. The reservoirs of influenza A viruses The available evidence indicates that aquatic birds are the reservoirs of all 15 subtypes of influenza A viruses. We will first consider the replication of influenza A in aquatic birds. In wild ducks, influenza viruses replicate preferentially in the cells lining the intestinal tract, cause no disease signs, and 8 7 are excreted in high concentrations in the feces (up to 10 .




Achieving Sustainable Global Capacity for Surveillance and Response to Emerging Diseases of Zoonotic Origin


Book Description

One of the biggest threats today is the uncertainty surrounding the emergence of a novel pathogen or the re-emergence of a known infectious disease that might result in disease outbreaks with great losses of human life and immense global economic consequences. Over the past six decades, most of the emerging infectious disease events in humans have been caused by zoonotic pathogens-those infectious agents that are transmitted from animals to humans. In June 2008, the Institute of Medicine's and National Research Council's Committee on Achieving Sustainable Global Capacity for Surveillance and Response to Emerging Diseases of Zoonotic Origin convened a workshop. This workshop addressed the reasons for the transmission of zoonotic disease and explored the current global capacity for zoonotic disease surveillance.




Zoonoses - Infections Affecting Humans and Animals


Book Description

The book will cover the most important zoonoses with a public health impact and debate actual developments in this field from a One Health perspective. The outline of the book follows a “setting” approach, i.e. special settings of zoonoses with a public health aspect, rather than presenting a simple textbook of an encyclopedic character. Main chapters will deal with zoonoses in the food chain including a special focus on the emerging issue of antibiotic resistance, with zoonoses in domestic and pet animals, in wildlife animal species (including bats as an important infectious agent multiplier), influenza and tuberculosis as most prominent zoonoses, and zoonotic pathogens as bioterroristic agents. Special interest chapters debate non-resolved and currently hotly debated zoonoses (e.g. M. Crohn/paratuberculosis, chronic botulism) as well as the economic and ecological aspects of zoonoses.




Animal-Origin Viral Zoonoses


Book Description

This book is the second volume in the series Livestock Diseases and Management, and reviews the importance and implications of animal origin viral zoonoses. It also highlights the specific etiology and epidemiology of these viral infections and discusses their various biological and mechanical transmission mechanisms. Further, the book reviews various measures for controlling viral zoonoses and examines novel therapeutic and prophylactic strategies. Discussing recent studies on the pathogenesis and host immune response to these infections, it underscores the importance of using vaccines against these viral diseases to reduce the risk of them being transmitted to humans.Lastly, it describes in detail the challenges posed by these viral infections and our readiness to face them.




Zoonoses


Book Description

Zoonoses are a persistent threat to the global human health Today, more than 200 diseases occurring in humans and animals are known to be mutually transmitted. Classical infectious diseases, such as rabies, plague, and yellow fever, have not been eradicated despite major efforts. New zoonotic diseases are on the increase due global conditions such as overpopulation, wars, and food scarcity, which facilitate human contact with rodents, stray animals, and their parasites. In addition, humans are unwittingly becoming accidental hosts and new links in an infectious chain by engaging in activities such as survival training, which involves camping in open areas and consumption of raw or insufficiently cooked food. Zoonotic infections cause a variety of symptoms that often do not provide clear evidence of a known disease. Zoonoses, Fourth Edition, describes most occurring worldwide zoonosis and facilitates the identification, diagnosis and treatment of zoonotic infections. Written by a team of doctors, medical microbiologists and veterinarians, this completely, revised edition covers all aspects of the epidemiology and prevention of zoonotic diseases through clear descriptions of various illnesses. Specifically, this fourth edition covers zoonosis caused by viruses, bacteria, fungi and parasites infections caused by animal bites infections and intoxications by animal foods Iatrogenic transmission of zoonotic pathogens Zoonoses is an indispensable reference for clinicians and laboratorians.
