Arenaviruses I


Book Description

Since the subject of arenaviruses was visited by Current Topics in Microbiology and Immunology 14 years ago, enormous advances have been made in this area. The receptor for several arenaviruses, alpha-dystroglycan, was identified, the replication strategy of these viruses was decoded, and application of a reverse genetics system for studying viral gene function and viral biology is well underway. In addition to reviewing these advances, Volume I includes discussion of arenaviral molecular phylogeny, reservoirs in rodents and clinical diseases caused by both new world and old world arenaviruses.




The Lassa Ward


Book Description

Ross Donaldson is one of just a few who have ventured into dark territory of a country ravaged by war to study one of the world's most deadly diseases. As an untried medical student studying the intersection of global health and communicable disease, Donaldson soon found himself in dangerous Sierra Leone, on the border of war-struck Liberia, where he struggled to control the spread of Lassa Fever. The words, "you know Lassa can kill you, don't you?" haunted him each day. With the country in complete upheaval and working conditions suffering, he is forced to make life-and-death decisions alone as a never-ending onslaught of contagious patients flood the hospital. Soon however, he is not only fighting for others but himself when he becomes afflicted with a life threatening disease. The Lassa Ward is more than just an adventure story about the making of a physician; it is a portrait of the Sierra Leone people and the human struggle of those risking their daily comforts and lives to aid them.




Lassa Fever


Book Description

Lassa virus causes Lassa fever disease in several countries in West Africa, where it is estimated to infect up to half million people causing roughly five thousand deaths each year. This deadly virus has also been introduced in multiple occasions into the western world, including the United States, United Kingdom, Netherlands, Sweden, and Germany. Lassa virus infection, which is often misdiagnosed, can lead to a wide range of disease symptoms ranging from mild flu-like symptoms to bleeding disorders, multi-organ failure, and death. Despite some major discoveries made in recent years of research on Lassa fever, there are still many unresolved key issues that hamper the development of effective vaccines and therapies. Some of these issues include a detailed understanding of the viral and participating host factors in completing the virus life cycle, in mediating disease pathogenesis or protection, and in activating or suppressing host immune responses against virus infection. This book is devoted to understanding some of these important issues. Expert and timely contributions in the form of editorial and original research and review articles on Lassa fever viral replication, disease pathogenesis and protection, host immune modulations, and other related hot topics are presented in this publication.




Fenner and White's Medical Virology


Book Description

Fenner and White's Medical Virology, Fifth Edition provides an integrated view of related sciences, from cell biology, to medical epidemiology and human social behavior. The perspective represented by this book, that of medical virology as an infectious disease science, is meant to provide a starting point, an anchor, for those who must relate the subject to clinical practice, public health practice, scholarly research, and other endeavors. The book presents detailed exposition on the properties of viruses, how viruses replicate, and how viruses cause disease. These chapters are then followed by an overview of the principles of diagnosis, epidemiology, and how virus infections can be controlled. The first section concludes with a discussion on emergence and attempts to predict the next major public health challenges. These form a guide for delving into the specific diseases of interest to the reader as described in Part II. This lucid and concise, yet comprehensive, text is admirably suited to the needs of not only advanced students of science and medicine, but also postgraduate students, teachers, and research workers in all areas of virology. - Features updated and expanded coverage of pathogenesis and immunity - Contains the latest laboratory diagnostic methods - Provides insights into clinical features of human viral disease, vaccines, chemotherapy, epidemiology, and control




Arenaviruses


Book Description

M. B. A. OLDSTONE Viruses are generally studied either because they cause significant human, animal or plant disease or for their utility as materials to probe a basic phenomenon in biology, chemistry, genetics or molecular biology. Arenaviruses are unusually interesting in that they occupy both of these categories. Arenaviruses cause severe human diseases known primarily as the hemor rhagic fevers occurring in South and Latin America (Bolivia: Machupo virus and Argentina: Junin virus) and in Africa (Lassa virus). Because such viruses produce profound disability and may kill the persons they infect, they are a source of economic hardship in the countries where they are prevalent. Further, they provide new problems for health care personnel owing to the narrowing of the world as visitors from many countries increasingly travel to and from these endemic areas. In addition, lymphocytic choriomeningitis virus (LCMV) can infect humans worldwide, although the illness is most often less disabling than those elicited by other arenaviruses. Yet LCMV is likely of greater concern to non-arena-virologists and experimentalists using tissue culture or animals, i. e. , workers in molecular biology, cancer research, virology, immunobiology, etc. , because normal appearing cultured cells or tissues and animals used for research may be persistently infected with LCMV without manifesting clinical disease or cytopathology and transmit that infection to laboratory workers (reviewed OLDSTONE and PETERS 1978). For example, HINMAN et al.




Infectious Diseases Emergencies


Book Description

Infectious Diseases Emergencies is a compact reference that summarizes the key topics of those infectious disease processes that are most commonly seen in practice. The opening section reviews principles of management and general management of severe infection in acute and emergency environments. The following sections provide a "head-to-toe" synopsis of common infections presenting in both outpatient and acute care settings. The concluding sections discuss vector borne infections, infections in special populations, and bioterrorism. Concisely written and consistently organized chapters outline the most useful elements of diagnosis and treatment for easy memorization and clarity.




Clinical Management of Patients with Viral Haemorrhagic Fever


Book Description

First published in March 2014 under the title "Clinical management of patients with viral haemorrhagic fever: a pocket guide for front-line health workers: interim emergency guidance for West Africa".




The Ebola Epidemic in West Africa


Book Description

The most recent Ebola epidemic that began in late 2013 alerted the entire world to the gaps in infectious disease emergency preparedness and response. The regional outbreak that progressed to a significant public health emergency of international concern (PHEIC) in a matter of months killed 11,310 and infected more than 28,616. While this outbreak bears some unique distinctions to past outbreaks, many characteristics remain the same and contributed to tragic loss of human life and unnecessary expenditure of capital: insufficient knowledge of the disease, its reservoirs, and its transmission; delayed prevention efforts and treatment; poor control of the disease in hospital settings; and inadequate community and international responses. Recognizing the opportunity to learn from the countless lessons of this epidemic, the National Academies of Sciences, Engineering, and Medicine convened a workshop in March 2015 to discuss the challenges to successful outbreak responses at the scientific, clinical, and global health levels. Workshop participants explored the epidemic from multiple perspectives, identified important questions about Ebola that remained unanswered, and sought to apply this understanding to the broad challenges posed by Ebola and other emerging pathogens, to prevent the international community from being taken by surprise once again in the face of these threats. This publication summarizes the presentations and discussions from the workshop.

Using an easily accessible, highly templated format, Clinical Cases in Tropical Medicine, 2nd Edition, provides more than 100 realistic scenarios for tropical infectious diseases. Full-color photographs and maps, a convenient question-and-answer presentation, and succinct summary boxes help you identify and understand the tropical diseases you’re likely to encounter. This up-to-date 2nd Edition is an excellent resource and study tool for infectious diseases fellows, doctors preparing for exams in tropical medicine, primary care doctors with patients who are global travelers, and global health nurses and practitioners alike. Offers realistic scenarios for encountering patients in rural, resource-poor settings, presenting cases as "unknowns," just as in a real clinic or emergency situation. Covers newly emerging diseases such as Zika virus, severe fever with thrombocytopenia syndrome (SFTS), and knowlesi malaria. Features topics in migrant medicine of particular importance to clinicians in non-tropical countries, including louse-borne-relapsing fever, spinal brucellosis, and hyperreactive malarial splenomegaly. Includes "classic" tropical diseases such as African trypanosomiasis, chagas, leprosy, and yaws. Reflects the use of novel diagnostics used in resource-poor settings, as well as developing drug resistance in relevant cases. Provides a useful index and map that organize cases geographically, for a targeted approach to study. Serves as a companion to Manson's Tropical Diseases, with a reading list at the end of each case referring to the corresponding chapter in the larger text.




Fevers, Feuds, and Diamonds


Book Description

“Paul Farmer brings his considerable intellect, empathy, and expertise to bear in this powerful and deeply researched account of the Ebola outbreak that struck West Africa in 2014. It is hard to imagine a more timely or important book.” —Bill and Melinda Gates "[The] history is as powerfully conveyed as it is tragic . . . Illuminating . . . Invaluable." —Steven Johnson, The New York Times Book Review In 2014, Sierra Leone, Liberia, and Guinea suffered the worst epidemic of Ebola in history. The brutal virus spread rapidly through a clinical desert where basic health-care facilities were few and far between. Causing severe loss of life and economic disruption, the Ebola crisis was a major tragedy of modern medicine. But why did it happen, and what can we learn from it? Paul Farmer, the internationally renowned doctor and anthropologist, experienced the Ebola outbreak firsthand—Partners in Health, the organization he founded, was among the international responders. In Fevers, Feuds, and Diamonds, he offers the first substantive account of this frightening, fast-moving episode and its implications. In vibrant prose, Farmer tells the harrowing stories of Ebola victims while showing why the medical response was slow and insufficient. Rebutting misleading claims about the origins of Ebola and why it spread so rapidly, he traces West Africa’s chronic health failures back to centuries of exploitation and injustice. Under formal colonial rule, disease containment was a priority but care was not – and the region’s health care woes worsened, with devastating consequences that Farmer traces up to the present. This thorough and hopeful narrative is a definitive work of reportage, history, and advocacy, and a crucial intervention in public-health discussions around the world.
