This book was released on 2024-02-20 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ‘novel coronavirus disease’ (COVID-19) has caused significant global morbidity, mortality and economic damage on a scale similar to the influenza pandemic of 1918. The causative ‘severe acute respiratory syndrome virus 2’ (SARS-CoV-2) is a RNA virus which is evolving rapidly, accumulating mutations, and existing as a cloud of variants with quasispecies diversity. We have tens of thousands of variants, of which currently two are ‘variants of interest’ (Lambda, Mu) and another four ‘variants of concern’ (Alpha, Beta, Gamma, Delta, Omicron) to the World Health Organization (WHO). Variants of interest often emerge as variants under investigation in one or more countries, as seen with the Omicron (initially denoted as Nu in South Africa). They become variants of concern when there is evidence of increased transmissibility, greater case severity, loss of neutralization by antibodies, and reduced effectiveness of countermeasures. Some SARS-CoV-2 variants can infect new hosts (for instance, the Alpha, Beta and Gamma variants of concern can infect wild type mice which is a species that cannot be vaccinated or controlled easily), and/or reduce the effectiveness of vaccines and therapies (especially Beta and Delta); diagnostic tests have also been reported to be affected. Currently, we do not yet have any ‘variant of high consequence’ with confirmed attributes such as widespread diagnostic test failures, significant reduction in the effectiveness of vaccines and/or therapies, with greater disease severity and deaths. It remains to be seen if Omicron would be the first to be declared by the WHO as a variant of high consequence; more variants of concern are also likely to be declared by the WHO over the next couple of years. Therefore, our ability to control and conquer this pandemic over the long run is dependent on predicting and keeping up with the evolution of this virus, its new hosts, as well as understanding and mitigating its impact on diagnostics, vaccines and therapies.

This book was released on 2021-05-04 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate guide for anyone wondering how President Joe Biden will respond to the COVID-19 pandemic—all his plans, goals, and executive orders in response to the coronavirus crisis. Shortly after being inaugurated as the 46th President of the United States, Joe Biden and his administration released this 200 page guide detailing his plans to respond to the coronavirus pandemic. The National Strategy for the COVID-19 Response and Pandemic Preparedness breaks down seven crucial goals of President Joe Biden's administration with regards to the coronavirus pandemic: 1. Restore trust with the American people. 2. Mount a safe, effective, and comprehensive vaccination campaign. 3. Mitigate spread through expanding masking, testing, data, treatments, health care workforce, and clear public health standards. 4. Immediately expand emergency relief and exercise the Defense Production Act. 5. Safely reopen schools, businesses, and travel while protecting workers. 6. Protect those most at risk and advance equity, including across racial, ethnic and rural/urban lines. 7. Restore U.S. leadership globally and build better preparedness for future threats. Each of these goals are explained and detailed in the book, with evidence about the current circumstances and how we got here, as well as plans and concrete steps to achieve each goal. Also included is the full text of the many Executive Orders that will be issued by President Biden to achieve each of these goals. The National Strategy for the COVID-19 Response and Pandemic Preparedness is required reading for anyone interested in or concerned about the COVID-19 pandemic and its effects on American society.
Download or read book The Coronaviridae written by Stuart G. Siddell and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronaviruses were recognized as a group of enveloped, RNA viruses in 1968 and accepted by the International Committee on the Taxonomy of Viruses as a separate family, the Coronaviridae, in 1975. By 1978, it had become evident that the coronavirus genomic RNA was infectious (i. e. , positive strand), and by 1983, at least the framework of the coronavirus replication strategy had been per ceived. Subsequently, with the application of recombinant DNA techniques, there have been remarkable advances in our understanding of the molecular biology of coronaviruses, and a mass of structural data concerning coronavirus genomes, mRNAs, and pro teins now exists. More recently, attention has been focused on the role of essential and accessory gene products in the coronavirus replication cyde and a molecular analysis of the structure-function relation ships of coronavirus proteins. Nevertheless, there are still large gaps in our knowledge, for instance, in areas such as the genesis of coronavirus subgenomic mRNAs or the function of the coronavirus RNA-dependent RNA polymerase. The diseases caused by coronaviruses have been known for much longer than the agents themselves. Possibly the first coronavirus-related disease to be recorded was feline infectious peritonitis, as early as 1912. The diseases associ ated with infectious bronchitis virus, transmissible gastroenteritis virus, and murine hepatitis virus were all well known before 1950.

Download or read book Structural Virology written by Mavis Agbandje-McKenna and published by Royal Society of Chemistry. This book was released on 2010-11-11 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last ten years, much effort has been devoted to improving the biophysical techniques used in the study of viruses. This has resulted in the visualization of these large macromolecular assemblages at atomic level, thus providing the platform for functional interpretation and therapeutic design. Structural Virology covers a wide range of topics and is split into three sections. The first discusses the vast biophysical methodologies used in structural virology, including sample production and purification, confocal microscopy, mass spectrometry, negative-stain and cryo-electron microscopy, X-ray crystallography and nuclear magnetic resonance spectroscopy. The second discusses the role of virus capsid protein structures in determining the functional roles required for receptor recognition, cellular entry, capsid assembly, genome packaging and mechanisms of host immune system evasion. The last section discusses therapeutic strategies based on virus protein structures, including the design of antiviral drugs and the development of viral capsids as vehicles for foreign gene delivery. Each topic covered will begin with a review of the current literature followed by a more detailed discussion of experimental procedures, a step in the viral life cycle, or strategies for therapeutic development. With contributions from experts in the field of structural biology and virology this exceptional monograph will appeal to biomedical scientists involved in basic and /or applied research on viruses. It also provides up-to-date reference material for students entering the field of structural virology as well as scientists already familiar with the area.

Download or read book Economic Policy for a Pandemic Age written by Monica de Bolle and published by Peterson Institute for International Economics. This book was released on 2021-04-05 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The global health and economic threats from the COVID-19 pandemic are not yet behind us. While the development of multiple safe and highly effective vaccines in less than a year is cause for hope, several significant dangers to recovery of global health and income are still clear and present: New concerning variants of SARS-CoV-2, the virus that causes COVID-19, continue to emerge at an alarming rate in different parts of the world; at the same time, vaccine rollouts have been shockingly inefficient even in some rich countries, while much of the developing world waits in line behind them for vaccines to arrive. The Briefing covers several policy areas in which cooperative forward-looking policy action will materially improve our chances of truly escaping today's pandemic and making future pandemics less costly.
Download or read book New Advances on Zika Virus Research written by Luis Martinez-Sobrido and published by MDPI. This book was released on 2019-04-02 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zika virus (ZIKV) is a mosquito-borne member of the Flaviviridae family that historically has been associated with mild febrile illness. However, the recent outbreaks in Brazil in 2015 and its rapid spread throughout South and Central America and the Caribbean, together with its association with severe neurological disorders—including fetal microcephaly and Guillain-Barré syndrome in adults—have changed the historic perspective of ZIKV. Currently, ZIKV is considered an important public health concern that has the potential to affect millions of people worldwide. The significance of ZIKV in human health and the lack of approved vaccines and/or antiviral drugs to combat ZIKV infection have triggered a global effort to develop effective countermeasures to prevent and/or treat ZIKV infection. In this Special Issue of Viruses, we have assembled a collection of 32 research and review articles that cover the more recent advances on ZIKV molecular biology, replication and transmission, virus–host interactions, pathogenesis, epidemiology, vaccine development, antivirals, and viral diagnosis.
Download or read book Socio Life Science and the COVID 19 Outbreak written by Makoto Yano and published by Springer Nature. This book was released on 2022 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents the first step towards building socio-life science, a field of science investigating humans in such a way that both social and life-scientific factors are integrated. Because humans are both living and social creatures, a human action can never be understood fully without knowing both the biological traits of a person and the social scientific environments in which he exists. With this consideration, the editors of this book have initiated a research project promoting a deeper and more integrated understanding of human behavior and human health. This book aims to show what can, and could be, achieved through our interdisciplinary project. One important product is the newly formed three-party collaboration between Pasteur Institut, Kyoto University, and the Research Institute of Economy, Trade and Industry. Covering many different fields, including medicine, epidemiology, anthropology, economics, sociology, demography, geography, and policy, researchers in these institutes, and many others, present their studies on the COVID-19 pandemic. Although based on different methodologies, the studies show the importance of behavioral change and governmental policy in the fight against a huge pandemic. The book explains the unique genome cohort-panel data that the project builds to study social and life scientific aspects of humans.
Download or read book Learning from SARS written by Institute of Medicine and published by National Academies Press. This book was released on 2004-04-26 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of severe acute respiratory syndrome (SARS) in late 2002 and 2003 challenged the global public health community to confront a novel epidemic that spread rapidly from its origins in southern China until it had reached more than 25 other countries within a matter of months. In addition to the number of patients infected with the SARS virus, the disease had profound economic and political repercussions in many of the affected regions. Recent reports of isolated new SARS cases and a fear that the disease could reemerge and spread have put public health officials on high alert for any indications of possible new outbreaks. This report examines the response to SARS by public health systems in individual countries, the biology of the SARS coronavirus and related coronaviruses in animals, the economic and political fallout of the SARS epidemic, quarantine law and other public health measures that apply to combating infectious diseases, and the role of international organizations and scientific cooperation in halting the spread of SARS. The report provides an illuminating survey of findings from the epidemic, along with an assessment of what might be needed in order to contain any future outbreaks of SARS or other emerging infections.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes state-of-the-art antiviral drug design and discovery approaches starting from natural products to de novo design, and provides a timely update on recently approved antiviral drugs and compounds in advanced clinical development. Special attention is paid to viral infections with a high impact on the world population or highly relevant from the public health perspective (HIV, hepatitis C, influenza virus, etc.). In these chapters, limitations associated with adverse effects and emergence of drug resistance are discussed in detail. In addition to classical antiviral strategies, chapters will be dedicated to discuss the non-classical drug development strategies to block viral infection, for instance, allosteric inhibitors, covalent antiviral agents, or antiviral compounds targeting protein–protein interactions. Finally, current prospects for producing broad-spectrum antiviral inhibitors will be also addressed. The book is distinctive in providing the most recent update in the rapidly evolving field of antiviral therapeutics. Authoritative reviews are written by international scientists well known for their contributions in their topics of research, which makes this book suitable for researchers not only within the antiviral research community but also attractive to a broad audience in the drug discovery field. This book covers molecular structures and biochemical mechanisms mediating the antiviral effects, while discussing various ligand design strategies, which include traditional medicinal chemistry, computational chemistry, and chemical biology approaches. The book provides a comprehensive review of antiviral drug discovery and development approaches, particularly focusing on current innovations and future trends.
Download or read book Blue Marble Health written by Peter J. Hotez and published by JHU Press. This book was released on 2016-09 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do diseases of poverty afflict more people in wealthy countries than in the developing world? In 2011, Dr. Peter J. Hotez relocated to Houston to launch Baylor’s National School of Tropical Medicine. He was shocked to discover that a number of neglected diseases often associated with developing countries were widespread in impoverished Texas communities. Despite the United States’ economic prowess and first-world status, an estimated 12 million Americans living at the poverty level currently suffer from at least one neglected tropical disease, or NTD. Hotez concluded that the world’s neglected diseases—which include tuberculosis, hookworm infection, lymphatic filariasis, Chagas disease, and leishmaniasis—are born first and foremost of extreme poverty. In this book, Hotez describes a new global paradigm known as “blue marble health,” through which he asserts that poor people living in wealthy countries account for most of the world’s poverty-related illness. He explores the current state of neglected diseases in such disparate countries as Mexico, South Korea, Argentina, Australia, the United States, Japan, and Nigeria. By crafting public policy and relying on global partnerships to control or eliminate some of the world’s worst poverty-related illnesses, Hotez believes, it is possible to eliminate life-threatening disease while at the same time creating unprecedented opportunities for science and diplomacy. Clear, compassionate, and timely, Blue Marble Health is a must-read for leaders in global health, tropical medicine, and international development, along with anyone committed to helping the millions of people who are caught in the desperate cycle of poverty and disease.
