Book Description
Avian influenza, or 'bird flu', is a contagious disease of animals caused by viruses that normally infect only birds and, less commonly, pigs. Avian influenza viruses are highly species-specific, but have, on rare occasions, crossed the species barrier to infect humans. In domestic poultry, infection with avian influenza viruses causes two main forms of disease, distinguished by low and high extremes of virulence. The so-called 'low pathogenic' form commonly causes only mild symptoms (ruffled feathers, a drop in egg production) and may easily go undetected. The highly pathogenic form is far more dramatic. It spreads very rapidly through poultry flocks, causes disease affecting multiple internal organs, and has a mortality that can approach 100%, often within 48 hours.

Book Description
In November 2018, an ad hoc planning committee at the National Academies of Sciences, Engineering, and Medicine planned two sister workshops held in Washington, DC, to examine the lessons from influenza pandemics and other major outbreaks, understand the extent to which the lessons have been learned, and discuss how they could be applied further to ensure that countries are sufficiently ready for future pandemics. This publication summarizes the presentations and discussions from both workshops.

Book Description
Avian influenza is a highly contagious viral disease, characterized by intense circulation in the wild waterbird reservoirs, with periodical introductions into the domestic poultry sector. AI viruses have been the source of devastating economic losses in the poultry industry over the last three decades, and have become a major veterinary and public health concern due to their zoonotic potential. The most emblematic illustration of this impact has been the emergence of the HPAI H5N1 virus in southern China in the mid-1990s, followed by its continental spread across East and Southeast Asia, and the unprecedented epidemics recorded in 2003–2004. More recently (from 2014 to 2017), several subtypes of HPAI (including H5N1, H5N6, H5N8) emerged in East Asia and spread intercontinentally, stressing the crucial role of this geographical hotspot as a source of new HPAI subtypes. The international dimension and the difficulty to effectively control those epidemics highlight the need for a global approach to HPAI surveillance and a comprehensive knowledge on epidemiology and patterns of the disease. This Research Topic aims at contributing to fill this gap. It includes ten papers which supplement the knowledge of the epidemiology of AI and offer new approaches on control strategies in various regions of the world.

Book Description
When, in late 2011, it became public knowledge that two research groups had submitted for publication manuscripts that reported on their work on mammalian transmissibility of a lethal H5N1 avian influenza strain, the information caused an international debate about the appropriateness and communication of the researchers' work, the risks associated with the work, partial or complete censorship of scientific publications, and dual-use research of concern in general. Recognizing that the H5N1 research is only the most recent scientific activity subject to widespread attention due to safety and security concerns, on May 1, 2012, the National Research Council's Committee on Science, Technology and Law, in conjunction with the Board on Life Sciences and the Institute of Medicine's Forum on Microbial Threats, convened a one-day public workshop for the purposes of 1) discussing the H5N1 controversy; 2) considering responses by the National Institute of Allergy and Infectious Diseases (NIAID), which had funded this research, the World Health Organization, the U.S. National Science Advisory Board for Biosecurity (NSABB), scientific publishers, and members of the international research community; and 3) providing a forum wherein the concerns and interests of the broader community of stakeholders, including policy makers, biosafety and biosecurity experts, non-governmental organizations, international organizations, and the general public might be articulated. Perspectives on Research with H5N1 Avian Influenza: Scientific Enquiry, Communication, Controversy summarizes the proceedings of the workshop.

Book Description
Avian influenza (AI) is caused by Influenza A viruses, and are single stranded, segmented RNA viruses of the family Orthomyxoviridae. Influenza A viruses continue to pose a major threat to the poultry industry and to the public. Wild aquatic birds are considered the primary hosts of influenza A, in which the virus is enzootic. In these birds, influenza viruses usually replicate in the intestinal tract, cause no disease, and spread by fecal contamination of the water habitat. This book discusses the epidemiology, global patters, and clinical management of Avian Influenza. It also examines the symptoms, treatment and clinical outcomes of Severe Acute Respiratory Syndrome (SARS), which is a highly contagious respiratory disease caused by a SARS coronavirus.

Book Description
Influenza is one of the most ancient and intriguing diseases that has been accompanying our civilization for millennia. While mankind has successfully defeated many dangerous influenza infections in the last couple of centuries, influenza control remains a serious problem for public health. A number of influenza vaccines and antiviral compounds have been licensed in recent times. However, the influenza virus is still ahead of us, as it continues to persistently infect humans to this day. Influenza: A Century of Research shows how influenza virology has developed historically and the tremendous knowledge that has been uncovered in the study of influenza. In this monograph, the authors present a historical perspective on influenza, chronologically, with an emphasis on its virology. Chapters cover information about the isolation of the first influenza viruses, substrates, and models for studying influenza, structure, and life cycle of the influenza virus, mechanisms of attenuation and virulence. Chapters progress into the multidisciplinary aspects of influenza research such as influenza virus ecology and the evolutionary origin of epidemic and pandemic influenza viruses. A significant part of the book also covers the description of the prevention and treatment of influenza and reasons that have contributed to insufficient control for influenza. The questions of how the COVID-19 pandemic affects the circulation of seasonal respiratory viruses, and if we can eliminate this virus are also addressed. Influenza: A Century of Research is an informative source of information for a broad range of readers, academic or otherwise, who are interested in knowing more about the disease.

Book Description
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.

Book Description
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.
