Japanese encephalitis and West Nile viruses are members of the Japanese encephalitis serological group of the genus Flavivirus and therefore closely related genetically and antigenically. They share a number of properties, including the use of birds as their major wildlife maintenance host and Culicine mosquitoes for transmission, and they are both associated with severe human disease, as well as fatal infections in horses. The emergence of these two viruses, and their well-established propensity to colonise new areas, make it timely to re-examine their ecology, biology, molecular structure, replication and epidemiology, and these therefore provide the focus of this volume.
West Nile virus is a neurotropic flavivirus that has emerged globally as a primary cause of viral encephalitis. Infection of humans and other vertebrate animals is associated with a febrile illness that can progress to a lethal encephalitis or flaccid paralysis syndrome. Its appearance in the Western Hemisphere in 1999 and the corresponding increase in global disease burden over the last decade have been accompanied by intensive study, including the entry of many scientists into the field. Breakthroughs have been made in understanding the unique transmission pattern between the vector and the multiple avian and mammalian hosts and targets. Studies in mammalian systems have dissected the viral and host factors that determine the pathogenesis and outcome of West Nile virus infection. On the basis of these experiments, progress has been made on the identification of genetic factors that predispose to severe human disease. Thus, in a remarkably short period of time, insight has been gained on a wide variety of disciplines related to West Nile virus biology. The aim of this book was to assemble an up-to-date and cutti- edge anthology from the leading experts in the field. The chapters are balanced by submissions from newcomers who have made significant recent contributions with those from established investigators who have dedicated their careers to the study of West Nile virus.

The Geographical Distribution of Animal Viral Diseases attempts to shed some light on the global distribution of 110 different viral diseases, mainly of livestock and companion animals. The world literature was screened for 110 different viruses, and maps were prepared. These maps delineate the global distribution of pathogenic viruses based on authenticated reports from a variety of reliable sources. Four viruses were categorized as affecting more than one species to a significant degree (astrovirus, rabies, rotaviruses, and Rift Valley fever). The largest number of maps involved viruses that affect humans. Of the 28 viruses a large number were from the California encephalitis group. Ten of the 28 viruses were reported only in the Eastern Hemisphere, 14 only in the Western Hemisphere, and four were worldwide. Birds were the next most frequently affected group with the 15 viruses, followed by pigs with 14 viruses. Overall the vector-borne viruses appear to have much sharper and clear-cut geographical boundaries than the others.
In this period of obvious natural emergence of viral and other diseases, it is unclear as to what diseases are emerging, why they are emerging, and what, if anything, can be done to prevent or diminish their impact. This book, a compendium of presentations made at an international meeting of experts, provides summaries of areas of concern and details as to how disease agents such as Nipah and Hendra viruses in Australasia and West Nile virus in the Americas might have suddenly appeared. Either by alterations in natural habitats and diversity or by chance, pathogens emerge from time to time. This book addresses various aspects of such emergences, such as pathogenetic mechanisms of viruses, diagnosis of viral infections, viral host-management strategies, viral genetics, vaccine development and application. It is especially valuable for laboratory virologists, disease ecologists, physicians, and those who want to understand the complexities of viral characteristics.
Der neue Band aus der Reihe International Society of Neuropathology wurde anlässlich der British Medical Association (BMA) Awards 2019 wärmstens empfohlen. Die Herausgeber sind Experten des Fachgebiets und beschreiben Infektionen des Nervensystems mit ihren klinischen, pathologischen und genetischen Eigenheiten. Auch seltene Erkrankungen werden in übersichtlichen Kapiteln erläutert, zusammen mit Definitionen, mikrobiologischen Eigenschaften, Epidemiologie, klinischen Ausprägungen, Labortests, Pathologie, Genetik und Behandlungsoptionen.
Meningitis and Encephalitis are associated with high rates of mortality and neurological sequelae. The differential diagnosis includes a wide spectrum of infectious and non-infectious etiologies, some requiring urgent therapy for survival. The current management challenges in patients with meningitis and encephalitis include a low sensitivity of meningeal signs, overutilization of unnecessary screening cranial imaging, delays in diagnosis of urgent treatable causes, a large proportion of unknown etiologies, low sensitivity of current microbiological techniques especially in the setting of previous antibiotic therapy, underutilization of available molecular diagnostic tests, and empiric antibiotic therapy and hospitalization for viral meningitis cases. Even though there are published guidelines, compliance with them is not optimal and physicians do not follow standardized algorithms in their empirical approach. As meningitis and encephalitis is associated with high rates of adverse clinical outcomes, prevention, when feasible is of upmost importance. Adherence to protocols to prevent health-care associated meningitis and ventriculitis are effective but compliance with them is not uniformly performed. This book seeks to improve outcomes for meningitis and encephalitis cases handled by physicians who may or may not be thoroughly trained for these challenges. The text introduces the current guidelines but also discusses the gaps that leave clinicians struggling to implement the most appropriate approaches for these particular neurological infections. Each chapter delivers the tools necessary to identify and adhere to the most appropriate diagnostic technique, management protocols, and prevention approach for each situation. All chapters conclude with discourse on future directions in research and quality improvement. Written by experts in infectious diseases, the book covers topics that are the most devastating, including healthcare-acquired infections, autoimmune encephalitis, and infections as they present in HIV patients. Meningitis and Encephalitis is a well-rounded resource for all medical professionals encountering these neurological syndromes, including infectious disease specialists, neurologists, primary care physicians, and immunologists.
In the fall of 1999 the mosquito-borne West Nile virus (WNV) killed 7 people in the NY City area and made dozens more very sick. It was initially misidentified as a different, related mosquito-borne virus often found in the U.S. The outbreak serves as a source of lessons about how public health (PH) officials can be better prepared in responding to potential crises involving uncertain causes, and how they can detect and respond to an act of biological terrorism. This report reviews the WNV outbreak and the response to it, focusing on establishing a chronological account of the events that occurred; and identifying lessons learned for PH and bioterrorism preparedness.
