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.

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.

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.

This report provides a review and analysis of the research landscape for zoonoses and marginalized infections which affect poor populations, and a list of research priorities to support disease control. The work is the output of the disease reference group on zoonoses and marginalized infectious diseases (DRG6), which is part of an independent think tank of international experts, established and funded by the Special Programme for Research and Training in Tropical Diseases (TDR), to identify key research priorities through the review of research evidence and input from stakeholder consultations. The report covers a diverse range of diseases including zoonotic helminth protozoa, viral and bacterial infections considered to be neglected and associated with poverty. Disease-specific research issues were elaborated under individual disease sections and many common priorities were readily identified among the disease such as need for new and/or improved drugs and regimens, diagnostics and, where appropriate, vaccines. The disease specific priorities are described as micro priorities compared with the macro level priorities which will drive such policies as the need for improved surveillance; the need for inter-sectoral interaction between health, livestock, agriculture, natural resources and wildlife in tackling the zoonotic diseases; and the need for a true assessment of the burden of the zoonoses. This is one of ten disease and thematic reference group reports that have come out of the TDR Think Tank, all of which have contributed to the development of the Global Report for Research on Infectious Diseases of Poverty.

The book begins with a review of zoonotic pandemics of the past: the “Black Death” or bubonic plague of the Middle Ages, the Spanish Influenza pandemic (derived from avian influenza) of the early 20th century, to the more modern pandemic of AIDS/HIV infection, which originated in Africa from primates. However, the majority of chapters focus on more recent zoonoses, which have been recognized since the late 20th century to the present: · SARS and MERS coronaviruses· New avian influenza viruses · The tick-borne Henan fever virus from China· The tick-borne Heartland virus from the United States · Recently recognized bacterial pathogens, such as Streptococcus suis from pigs. In addition, reemergence of established zoonoses that have expanded their niche are reviewed, such as the spread of Zika virus and Chikungunya virus to the Western Hemisphere, and the emergence and spread of Ebola virus infection in Africa. A chapter is also devoted to an overview of the mechanisms and various types of animals involved in the transmission of diseases to humans, and the potential means of control and prevention. Many endemic and sporadic diseases are still transmitted by animals, through either direct or indirect contact, and zoonoses are estimated to account for about 75% of all new and emerging infectious diseases. It is predicted by public health experts that the next major pandemic of infectious disease will be of animal origin, making Emerging Zoonoses: A Worldwide Perspective a crucial resource to all health care specialists by providing them with much needed information on these zoonotic diseases.iv>

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.

Infections between animals and humans are truly complex and health care providers should be aware of the potential role of animals in infectious diseases of HIV infected patients. The aim of this guideline is to outline the most important zoonoses that play a significant role in the epidemiology of AIDS and to provide a practical and manageable tool for health workers involved in the care of HIV infected humans.
