Download or read book A Closer Look at the COVID 19 Variants written by Richard D. Hylton and published by Nova Snova. This book was released on 2022-09-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021-02-15 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Evolution of SARS CoV 2 impact of variants on hosts COVID 19 vaccines and countermeasures written by Seshadri Vasan and published by Frontiers Media SA. 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2022-06-29 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: This curated collection of scientific papers on the origin and global spread of COVID-19 is a unique project that offers explanations at odds with mainstream views as the theme mainly focuses on Panspermia (viruses, microorganisms and their spores, and cometary arrival of even more complex cellular organisms).No other scientific group has paid attention to the temporal unfolding scientific order at the many required levels of understanding — astrobiological and astrophysical, geographical and the temporal order of global proportions, yet regional epidemics, the immunologic dimensions to the infection and epidemic data, the genetics of the SARS-CoV-2 virus as it adapted, varied and appeared in different human populations in the crucial first few months of the pandemic. This in-depth analysis, over a two-year period, allows a better understanding of what engulfed the world during the COVID-19 pandemic, how it happened and the most plausible way.There are many lessons for future generations that can be distilled from the contributions found in this book.
