Book Description
As viruses spread, small errors - called mutations - arise in the genetic material during replication. Many of these mutations are repaired or die off as the virus continues to move through a population. Mutations that enhance the virus's ability to replicate, transmit, or survive in a host allow the virus to spread more quickly through a population, or become more resistant to immune system defenses, thereby increasing the mutations' prevalence and creating a new strain of the virus. The purpose of this book is to discuss how variants develop, how researchers identify and sequence variants, and how this information can be utilized by public health officials, government agencies, and medical practitioners to make decisions. The book examines the ways the government can better coordinate its approach to best serve the American people through this pandemic and beyond.

Book Description
People live in a sea of viruses. All creatures are host to these small organisms, which are made up of small bits of genetic information. Viruses are possessed by a drive to survive, but in order to reproduce they must invade a living cell. Dr. William A. Haseltine, PhD, has spent a lifetime studying viruses and their ability to adapt and flourish within an ever-changing environment. In Variants! The Shape-Shifting Challenge of COVID-19, Dr. Haseltine turns his focus to SARS-CoV-2, the virus that causes COVID-19. The variant forms of this coronavirus risk an even greater disruption to our lives, our economy, and the health and wellbeing of hundreds of billions worldwide. Variants! is a collection of Dr. Haseltine's writings and research on COVID-19 and SARS-CoV-2 mutations and variants. The book is a Living eBook, updated regularly with new information as it unfolds. When a reader purchases a copy of the book, either in print or online, they will receive a special passcode that will give them online access to every subsequent edition of the book, as it is released.

Book Description
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.

Book Description
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.

Book Description
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.
