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.
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.
Arthropod-borne viruses (arboviruses) are the causative agents of significant morbidity and mortality among humans and domestic animals globally. They are maintained in complex biological life cycles, involving a primary vertebrate host and a primary arthropod vector. While all known arboviruses are zoonotic pathogens, their emergence as human pathogens is associated with dramatic increases of human population growth leading to uncontrolled urbanization, changes in land and water use, changes in agricultural practices, new irrigation systems and deforestation. This book brings together a panel of expert arbovirologists to produce a timely review of the rapidly expanding arbovirus research literature. In addition authors identify the most pressing questions that remain to be answered, thus providing a stimulus for future research. Topics include: taxonomy, genome organization, virus-host and virus-vector interactions, evolutionary history, role of vertical transmission in arbovirus maintenance and evolution, epidemiology, arbovirus replication, pathogenesis, arbovirus diagnostics and control, including vaccines, novel anti-viral drugs, RNA interference and genetically modified vectors. Essential reading for every arbovirologist and highly recommended for all virologists and public health officials.

The Togaviruses: Biology, Structure, Replication deals with the biology, structure, and replication of rotaviruses. This book covers topics such as the biochemistry of rotaviruses and the biological and medical challenges they pose. It also gives an account of their mechanisms of replication that might lead to perceptions of the capacity to solve biological and epidemiological problems through the concepts and technology of molecular biology. This text is comprised of 21 chapters that explore clinical details, routine procedures for diagnostic virus isolation and identification and for serological tests; immunological host responses; the role of interferons; antiviral chemotherapy; and vaccine development. The discussion begins with a historical overview of arboviruses, followed by a description of all the viruses that belong to Togaviridae. These include alpha- and flaviviruses, rubiviruses, pestiviruses, and other ""non-arbo"" togaviruses. The next chapters focus on the arthropod-vertebrate-arthropod transmission cycle and its experimental equivalents, along with the viruses' structure, composition, and replication. This book concludes with a summary of physicochemical, morphological, and clinical data on non-arbo togaviruses. This reference material will be of interest to physicians, veterinarians, ecologists, entomologists, epidemiologists, cell biologists, immunologists, virologists, physical chemists, biochemists, molecular biologists, and geneticists.
Over 50% of known flaviviruses have been associated with human disease. The Flavivirus genus constitutes some of the most serious human pathogens including Japanese encephalitis, dengue and yellow fever. Flaviviruses are known for their complex life cycles and epidemic spread, and are considered a globally-emergent viral threat. Detection, Diagnosis and Vaccine Development, the third volume of The Flaviviruses details the current status of technologies for detection and differentiation of these viruses, their use in surveillance and outbreak investigation, and also reviews the latest clinical research. - Comprehensive approach to the scientific disciplines needed to unravle the complexities of virus-host interactions - Descibes the technologies that have contributed to our current knowledge about the Flaviviruses - Identifies the major problems faced in understanding the virus-host interactins that result in disease - An exhaustive compendium of current and past knowledge on the Flavivirus family
Arthropod borne diseases cause enormous morbidity and mortality in most countries, mostly in those situated in tropical areas, but also in temperate regions. This book provides organized information on all arthropod related diseases, to prevent suffering and deaths, for medical students and professionals. Since arthropod borne diseases are present in many regions of the world and can even surprise professionals and lays in non-endemic regions, like malaria in UK and Canada, the author and its many expert collaborators are sure that it will be essential in all hospitals, clinics and medical libraries around the world. As arthropod borne diseases of domesticated animals are very numerous and in some cases related to human diseases, they are also included in the book.

Chikungunya, an arbovirus, is a major global threat affecting multiple areas of the world, even Europe, but recently (2014 - 2015) with large epidemics in Latin America, causing an important acute and chronic morbidity with a low, but present, mortality. This book tries to update the significant epidemiological and clinical research in many aspects with a multinational perspective. This book has been organized in two major sections: (I) ''Clinical and Epidemiological Aspects'' and (II) ''Entomology.'' Section I includes topics covering experiences and studies in different countries, including the infection during pregnancy and children, imported cases, ocular manifestations, coinfections, and therapeutics. Section II includes topics on entomological aspects, related to vector control, and new options for biological control of Aedes aegypti.
