The COVID-19 pandemic has presented unprecedented challenges to the nation's K-12 education system. The rush to slow the spread of the virus led to closures of schools across the country, with little time to ensure continuity of instruction or to create a framework for deciding when and how to reopen schools. States, districts, and schools are now grappling with the complex and high-stakes questions of whether to reopen school buildings and how to operate them safely if they do reopen. These decisions need to be informed by the most up-to-date evidence about the SARS-CoV-2 virus that causes COVID-19; about the impacts of school closures on students and families; and about the complexities of operating school buildings as the pandemic persists. Reopening K-12 Schools During the COVID-19 Pandemic: Prioritizing Health, Equity, and Communities provides guidance on the reopening and operation of elementary and secondary schools for the 2020-2021 school year. The recommendations of this report are designed to help districts and schools successfully navigate the complex decisions around reopening school buildings, keeping them open, and operating them safely.

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.

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.

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.

This book covers over 24 country studies on various dimensions associated with the geographical spread of COVID-19. The chapters in the book, from geographically diversified countries, assert the need to undertake intensive regional research in order to understand the global pattern of Coronavirus focusing on infection migration, and indigenous origin that has caused tremendous global economic, social and health disaster. The book contends that understanding of peoples’ behaviour is crucial towards safety measures against infection, as COVID-19 impacted to a greater extent social wellbeing of population because of lockdowns in all corners of the world. Some of the countries featured are USA, France, Italy, Hong Kong, South Korea, Canada, Australia, Pacific Islands, Russia, Taiwan, Thailand, Malaysia, Indonesia, India, South Africa, Nigeria, Mexico, Peru and Brazil.

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.
