The publication of this volume of The Viruses entitled The Togaviridae and Flaviviridae comes at an appropriate time. The structure and rep lication strategies of these viruses are now known to be sufficiently di verse to warrant the removal of flaviviruses from the Togaviridae family and establish them as an independent family. Flaviviridae have a special place in the history of virology. The prototype virus-yellow fever virus was the first virus to be identified as the cause of a human disease. Some of the history of this discovery is described in Chapter 1 of this volume; in Chapter 10 the complete sequence of the RNA genome of the virus is presented. This sequence not only defines the primary structure of the viral proteins, it also clarifies the mechanism of translation of the fla vivirus genome. Knowledge of the sequence of the structural proteins of these viruses represents an important step in the potential goal of using purified flavivirus glycoproteins as vaccines. Many of the chapters in this volume focus on the structure and replication of the Togaviridae. These viruses have provided valuable models for studies in cell biology, partic ularly with regard to the cotranslational and posttranslational steps re quired for the synthesis and localization of membrane glycoproteins. Fur thermore, Togaviridae have been pivotal in our growing understanding of how enveloped viruses enter and exit from cells. The broad outlines of the structure and gene expression of Togavir idae and Flaviviridae are known, but important questions remain.

Striking changes have occurred in the world since the publication of the last edition of Viral Infections of Humans. The global population is rapidly approaching 8 billion; climate change is leading to the introduction of new hosts, vectors and virus diseases heretofore never seen in many parts of the world; technological advances have revolutionized the ability to recognize and characterize viruses new and old; vaccines are altering the epidemiological landscape of the diseases they target, in some cases raising the hope of their eradication and remarkably powerful computational tools are enabling not only detection of outbreaks of disease much sooner than in the past but also, through complex mathematical modeling, more accurate prediction of their potential impact. The new Fifth Edition of Viral Infections of Humans captures the both the excitement and frustration of the dynamic struggle between humankind and the viruses that continue to cause immense suffering. It presents the latest concepts, methods and technologies in epidemiology, detection, investigation, modeling and intervention. Updated and entirely new chapters by dozens of experts across the field provide analytic summaries of current knowledge of viruses and prions causing acute syndromes, chronic illnesses and/or malignancies. In sum, this ambitiously expanded volume offers a uniquely comprehensive perspective on viruses in humans, from agents of classic diseases (e.g., hepatitis, measles, polio, rabies and yellow fever), to those with greatest pandemic impact (e.g., influenza and human immunodeficiency virus), to those discovered relatively recently (e.g., henipavirus, metapneumovirus and norovirus). The new Fifth Edition of Viral Infections of Humans is an invaluable reference for students, fellows and established professionals in the fields of microbiology, public health and infectious disease epidemiology, medicine and health policy.

Flaviviruses are a diverse group of small RNA enveloped viruses, many of which are important human and animal pathogens. The best known include dengue virus, yellow fever virus, Japanese encephalitis virus, and West Nile virus. These viruses are endemic in many tropical and sub-tropical regions of the world. Dengue virus alone infects over 100 million people annually. In recent years, research on flaviviruses has progressed at a remarkable rate, leading to significant advances in our understanding of virus biology; this should ultimately lead to the development of better vaccine and antiviral strategies. The editor of Molecular Virology and Control of Flaviviruses has assembled an up-to-date and cutting-edge anthology from the leading experts in the flavivirus field. Chapters are balanced by contributions from established investigators, who have dedicated their careers to flavivirus research, with those from newcomers who have recently made significant contributions to the flavivirus field. The book opens with a brief introduction then divides into two sections: Molecular Virology (Chapters 2-9) and Virus Prevention (Chapters 10-15). The first section covers: virion structure; virus replication; the NS1 glycoprotein; the NS3 protein; the NS5 protein; innate immunity and flavivirus infection; host responses to flavivirus infection; and flavivirus fitness and transmission. The second section includes: vaccines; antibody therapy; small molecule antiviral development; flavivirus diagnostics; vector-virus interactions; and vector control. The book represents an important update of flavivirus research and will serve as a reference to flavivirus researchers at the graduate level and beyond. A recommended text for all virology libraries.

The practical need to partition the world of viruses into distinguishable, universally agreed upon entities is the ultimate justification for developing a virus classification system. Since 1971, the International Committee on Taxonomy of Viruses (ICTV) operating on behalf of the world community of virologists has taken on the task of developing a single, universal taxonomic scheme for all viruses infecting animals (vertebrate, invertebrates, and protozoa), plants (higher plants and algae), fungi, bacteria, and archaea. The current report builds on the accumulated taxonomic construction of the eight previous reports dating back to 1971 and records the proceedings of the Committee since publication of the last report in 2005. Representing the work of more than 500 virologists worldwide, this report is the authoritative reference for virus organization, distinction, and structure.

Despite vaccines and medicines, we have not succeeded in eradicating the most poisonous viruses in the world, like jaundice, measles, diarrhea, polio, and AIDS, not to mention newcomers like West Nile and SARS. Also, since September 11, it is no longer unthinkable that a terrorist would intentionally spread a virus among people or the food chain. In this book, Jaap Goudsmit argues that there is no such thing as life without viruses for many reasons; including the fact that many viruses spread without any visible signs, and can hide in animals; that there are too many different species of viruses and they multiply much faster than any animal or plant; and that infections strike especially in areas where life is difficult enough already, such as Africa and Asia. However, Goudsmit continues, if viruses hold onto life so stubbornly, perhaps they can be useful to other living beings. Do viruses offer people a better chance of survival in a hostile world? Do viruses make people fitter? Some viruses seem to play a role in the process whereby our genes adapt to the environment. What is it that makes viruses incredibly strong, and can we learn something from it? What is the secret of the enormous "fitness" of viruses? Will viruses spell the end of mankind or will man always be able to offer resistance? This book attempts to answer these and other questions.

The story of viruses and humanity is a story of fear and ignorance, of grief and heartbreak, and of great bravery and sacrifice. Michael Oldstone tells all these stories as he illuminates the history of the devastating diseases that have tormented humanity, focusing mostly on the most famous viruses. Oldstone begins with smallpox, polio, and measles. Nearly 300 million people were killed by smallpox in this century alone and the author presents a vivid account of the long campaign to eradicate this lethal killer. Oldstone then describes the fascinating viruses that have captured headlines in more recent years: Ebola, Hantavirus, mad cow disease (a frightening illness made worse by government mishandling and secrecy), and, of course, AIDS. And he tells us of the many scientists watching and waiting even now for the next great plague, monitoring influenza strains to see whether the deadly variant from 1918--a viral strain that killed over 20 million people in 1918-1919--will make a comeback. For this revised edition, Oldstone includes discussions of new viruses like SARS, bird flu, virally caused cancers, chronic wasting disease, and West Nile, and fully updates the original text with new findings on particular viruses. Viruses, Plagues, and History paints a sweeping portrait of humanity's long-standing conflict with our unseen viral enemies. Oldstone's book is a vivid history of a fascinating field, and a highly reliable dispatch from an eminent researcher on the front line of this ongoing campaign.
