Current Topics In Sars Cov 2 Covid 19

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has probably been the most important disease to emerge in the 21st century. This viral zoonotic disease has been a significant cause of morbidity and mortality worldwide, but with a higher impact in low- and middle-income countries of Africa, Asia, and Latin America. Up to December 4, 2022, more than 645,195,564 cases had been reported globally, with 6,640,845 deaths, and more than 13,054,668,703 doses of a vaccine had been given. Research has been of the utmost importance in the COVID-19 crisis: a great deal of knowledge was gathered between December 2019 and December 2022. Appropriate evidence-based management and the development of safe and effective vaccines have been key to controlling the virus. This book presents a selection of the last two years’ learning from research and clinical practice concerning SARS-CoV-2/COVID-19.

Since the identification of the first cases of the coronavirus in December 2019, there has been a significant amount of confusion regarding the origin and spread of the so-called 'coronavirus', SARS-CoV-2, and the cause of the disease COVID-19. Conflicting messages from the media and officials across different countries and organizations, the abundance of disparate sources of information, unfounded conspiracy theories on the origins of the virus, unproven therapies, and inconsistent public health measures, have all served to increase anxiety in the population. Where did the virus come from? How is it transmitted? How does it cause disease? Is it like flu? What is a pandemic? In this concise and accessible introduction, a leading expert provides answers to these commonly asked questions. This revised and updated edition now also covers how the virus mutates, how important these mutations are, how vaccines work, and what we can expect in the near and long-term future.

Corona virus disease or COVID-19 or SARS-CoV-2 infection is the latest pandemic that has affected humans globally. The disease has manifested itself in several forms and is now the focus of research worldwide. This book covers all the clinical aspects of the novel corona virus disease, COVID-19, which is one of the most contagious diseases ever known. It includes topics related to basic sciences, such as the virology and pathophysiology of the SARS-CoV-2 disease. It includes chapters related to symptomatology of the disease and making diagnosis, preparation of the health care workers to deal with this global pandemic. The book includes chapters on anesthetic and intensive care management of COVID-19 disease victims as these topics are of vast importance. Additionally, it includes a chapter giving insight in to the ethical aspects of the issues raised regarding disposal of bodies of the victims, as this pandemic has taken many lives across the world. It includes a chapter on special considerations to patient population such as geriatrics, pediatrics and pregnant women. The book serves as a useful resource for practitioners and clinicians in any field of medicine. It is also relevant for residents, trainees, fellows pursuing their courses in emergency medicine, anesthesia and critical care as well as postgraduates and even undergraduates. The book will serve as a ready-reckoner and useful guide for physicians from varied specialties during their clinical practice.

In this difficult period of the SARS-CoV-2 (and its variants) infection responsible for Covid-19 diseases, the importance of scientific works and reviews dealing with these viruses has never been more essential and vital. Reports as of 20th April 2021 indicate over 141 million cases of SARS-CoV-2 infection worldwide (with over 3 million deaths recorded). This volume brings together essential data regarding prevention (vaccination), detection, and various approaches (chemotherapeutic drugs and antibodies) to the potential treatment of coronavirus infections. It presents six chapters concerning the following topics: (1) the resistance to the spread of SARS-CoV-2 and related Covid-19 diseases within a population based on the pre-existing immunity of a high proportion of individuals as a result infection or previous vaccination (2) the impact of the Covid-19 pandemic for the South Asian Association for Regional Cooperation (SAARC) region, comprising the Bangladesh, Bhutan, Maldives, Nepal, Pakistan, Sri Lanka, India, and Afghanistan (3) the effect of candidate drugs chloroquine and hydroxychloroquine on QT interval in infected patients with Covid-19 diseases (4) the antiviral potential of herbal-based immunomodulators (5) the humoral immune response in humans based on anti-SARS-CoV-2 antibodies to treat Covid-19 diseases (6) the various methods and strategies for diagnosing SARS-CoV-2 (and its variants) infection in hosts/humans. This compilation should prove to be a tool of crucial importance for researchers around the world working on research revolving around coronaviruses, as well as for clinicians confronted by a growing number of patients with COVID-19. [Series Introduction] Coronaviruses presents compilations of reviews which present information about coronaviridae. Volumes in the series present interesting data on the virology, molecular biology, pathogenesis and epidemiology of these viruses. Current topics such as SARS-CoV-2 infection, COVID-19 epidemiology, economic impact of COVID-19, and new coronavirus variants are also included. The series should prove to be an essential resource on this group of viruses for multidisciplinary researchers and healthcare professionals alike.

In this issue of Infectious Disease Clinics of North America, guest editors Drs. Rachel Bender Ignacio and Rajesh T. Gandhi bring their considerable expertise to the topic of COVID-19 Infection. The evolving virology, wide range of symptoms, long-term health issues, mortality rate, effect on hospitals, and high transmission rate have made COVID-19 one of the worst health crises in recent times. In this issue, top experts in the field address key issues such as diagnostic testing, COVID-19 in pediatrics, post-acute sequelae, infection control, and much more, aiming to arm clinicians with the information they need to combat this deadly infection. Contains 15 relevant, practice-oriented topics including COVID-19 and global pandemic response, SARS CoV-2 transmission and prevention, COVID-19 Vaccines, COVID-19 treatment, equity and racial/ethnic disparities, and more. Provides in-depth clinical reviews on COVID-19, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

This update on SARS-CoV-2 focuses on basic knowledge about the virus and COVID-19 treatment. Chapters present basic information about the disease and its treatment. The virology, epidemiology, etiology, and damage response framework of SARS-CoV-2 are also discussed in detail. The book also covers recent topics of interest to pharmacology scholars such as the immunopathogenesis of SARS-CoV2, nanotechnology, repurposed drug treatments, COVID-19 vaccines, and phytomedicine for COVID-19 therapeutics. Readers in pharmacology, virology and medicine will find the book a simple, yet informative update on SARS-CoV-2 and COVID-19 treatment.

An Epidemiological Update on COVID-19 brings recent findings about the pandemic to the forefront. The reference is a compilation of eleven chapters contributed by expert scholars in epidemiology and medicine that cover topics of interest to anyone interested in COVID-19 monitoring and response measures. The topics also indicate some clinical areas of interest to COVID-19 researchers that have received attention due to the pandemic. It covers basic knowledge about respiratory conditions associated with SARS-CoV-2 infection and COVID-19 epidemiology. These topics are complemented with chapters detailing the symptoms and biochemical mechanisms of novel coronavirus infections intended for readers with an advanced level of understanding of life sciences and medicine. Special topics such as the immune response to Sars-CoV-2, and, recombinant drugs for COVID-19, are also covered in this book. Each chapter is organized in a reader-friendly format and includes a list of references.
