Learning from SARS
Author: Institute of Medicine
Publisher: National Academies Press
ISBN: 0309182158
Category : Medical
Languages : en
Pages : 376
Book Description
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.

The COVID-19 Catastrophe
Author: Richard Horton
Publisher: John Wiley & Sons
ISBN: 1509546456
Category : Medical
Languages : en
Pages : 143
Book Description
The global response to the COVID-19 pandemic is the greatest science policy failure in a generation. We knew this was coming. Warnings about the threat of a new pandemic have been made repeatedly since the 1980s and it was clear in January that a dangerous new virus was causing a devastating human tragedy in China. And yet the world ignored the warnings. Why? In this short and hard-hitting book, Richard Horton, editor of the medical journal The Lancet, scrutinizes the actions that governments around the world took – and failed to take – as the virus spread from its origins in Wuhan to the global pandemic that it is today. He shows that many Western governments and their scientific advisors made assumptions about the virus and its lethality that turned out to be mistaken. Valuable time was lost while the virus spread unchecked, leaving health systems unprepared for the avalanche of infections that followed. Drawing on his own scientific and medical expertise, Horton outlines the measures that need to be put in place, at both national and international levels, to prevent this kind of catastrophe from happening again. Were supposed to be living in an era where human beings have become the dominant influence on the environment, but COVID-19 has revealed the fragility of our societies and the speed with which our systems can come crashing down. We need to learn the lessons of this pandemic and we need to learn them fast because the next pandemic may arrive sooner than we think.

Role of Essential Oils in the Management of COVID-19
Author: Ahmed Al-Harrasi
Publisher: CRC Press
ISBN: 1000474631
Category : Medical
Languages : en
Pages : 865
Book Description
Coronavirus disease 2019 (COVID-19) has emerged as a global health threat. Unfortunately, there are very limited approved therapeutics available with established efficacy and safety profiles against SARS-CoV-2. COVID-19 vaccines aim to actively induce systemic immunization; however, the possibility or fear of side effects decreases or discourages their use. Alternative therapy via natural products, especially essential oils, could be considered safe and effective to improve health, cure ailments, and soothe your body and mind. Essential oils, which have been known for their anti-inflammatory, immunomodulatory, bronchodilatory, and antiviral properties, could possibly be useful for the symptomatic management of COVID-19. This book is vital in respect of designing approaches to protect humanity from further losses and harm due to SARS-CoV-2 infection. Role of Essential Oils in the Management of COVID-19 offers a complete outline of the recent novel coronavirus (SARS-CoV-2) infection, its biology, and associated challenges for the prevention and treatment of novel COVID-19, with a prime focus on the possible role of essential oils in the prevention and treatment of COVID-19. This book is written for everyone who needs to be thoroughly familiar with the appropriate and safe use of essential oils in COVID-19 therapy. As per the objectives of the book: The first seven chapters cover various aspects of COVID-19 infection, including epidemiology, origin, morphology, genome organization, pathogenesis, clinical manifestations, diagnostic approaches, preventive measures, and treatment strategies. The remaining chapters elaborate on the various aspects related to essential oils, such as chemistry, extraction methods, dispensing methods, stability, quality control, mechanism of action, therapeutic effects, pharmacokinetics, aromatherapy, and safety profiles. Prof. Ahmed Al-Harrasi is Vice Chancellor for Graduate Studies, Research and External Relations, Natural and Medical Sciences Research Center, and Professor of Organic Chemistry, University of Nizwa, Oman. Prof. Ahmed received his M.Sc. degree in Chemistry followed by his Ph.D. in Organic Chemistry from the University of Berlin. He then pursued his postdoctoral research at Cornell University.

The Origins of COVID-19
Author: Li Zhang
Publisher: Stanford University Press
ISBN: 1503630188
Category : Social Science
Languages : en
Pages : 153
Book Description
A new strain of coronavirus emerged sometime in November 2019, and within weeks a cluster of patients began to be admitted to hospitals in Wuhan with severe pneumonia, most of them linked to the Huanan Seafood Wholesale Market. China's seemingly effective containment of the first stage of the epidemic, in glaring contrast with the uncontrolled spread in Europe and the United States, was heralded as a testament to the Chinese Communist Party's unparalleled command over the biomedical sciences, population, and economy. Conversely, much academic and public debate about the origins of the virus focuses on the supposedly "backwards" cultural practice of consuming wild animals and the perceived problem of authoritarianism suppressing information about the outbreak until it was too late. The Origins of COVID-19, by Li Zhang, shifts debate away from narrow cultural, political, or biomedical frameworks, emphasizing that we must understand the origins of emerging diseases with pandemic potential (such as SARS and COVID-19) in the more complex and structural entanglements of state-making, science and technology, and global capitalism. She argues that both narratives, that of China's victory and the racist depictions of its culpability, do not address—and even aggravate—these larger forces that degrade the environment and increase the human-wildlife interface through which novel pathogens spill over into humans and may rapidly expand into global pandemics.

Pain Management and the Opioid Epidemic
Author: National Academies of Sciences, Engineering, and Medicine
Publisher: National Academies Press
ISBN: 0309459575
Category : Medical
Languages : en
Pages : 483
Book Description
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.
