From Dr. Wang Zhou and his colleagues at the Wuhan Center for Disease Control and Prevention comes a must-have guide for preparing for an outbreak of the coronavirus virus (COVID-19). The Center for Disease Control and Prevention in the US and the World Health Organization have declared the coronavirus a worldwide health emergency. The coronavirus was first identified in Wuhan, China. Now, from the medical experts there, comes the first authoritative, comprehensive guide to preparing for the ongoing epidemic (COVID-19). Written in plain language, here is information that will help readers and professionals understand the virus and protect themselves in the face of a possible outbreak. As COVID-19 continues to spread around the world—China, South Korea, Iran, Italy, Germany, the United Kingdom, Canada, and the United States—preventative measures such as controlling the source of infection, early detection of patients, and cutting off transmission are imperative. With 101 tips for individuals to prevent the spread of the virus, the information in this handbook could be lifesaving. The prevention tips include: Precautions for individuals and public places (handwashing, face masks, etc.) Strategies for detection and treatment of the disease An overview of the coronavirus and how it’s spread Basics about contagious diseases With the number of reported cases of COVID-19 growing daily, the information in this book will help you protect yourself and your loved ones!
This book will serve as a primer for both laboratory and field scientists who are shaping the emerging field of molecular epidemiology. Molecular epidemiology utilizes the same paradigm as traditional epidemiology but uses biological markers to identify exposure, disease or susceptibility. Schulte and Perera present the epidemiologic methods pertinent to biological markers. The book is also designed to enumerate the considerations necessary for valid field research and provide a resource on the salient and subtle features of biological indicators.
Hepatitis B and C cause most cases of hepatitis in the United States and the world. The two diseases account for about a million deaths a year and 78 percent of world's hepatocellular carcinoma and more than half of all fatal cirrhosis. In 2013 viral hepatitis, of which hepatitis B virus (HBV) and hepatitis C virus (HCV) are the most common types, surpassed HIV and AIDS to become the seventh leading cause of death worldwide. The world now has the tools to prevent hepatitis B and cure hepatitis C. Perfect vaccination could eradicate HBV, but it would take two generations at least. In the meantime, there is no cure for the millions of people already infected. Conversely, there is no vaccine for HCV, but new direct-acting antivirals can cure 95 percent of chronic infections, though these drugs are unlikely to reach all chronically-infected people anytime soon. This report, the second of two, builds off the conclusions of the first report and outlines a strategy for hepatitis reduction over time and specific actions to achieve them.
Forest land managers face the challenges of preparing their forests for the impacts of climate change. However, climate change adds a new dimension to the task of developing and testing science-based management options to deal with the effects of stressors on forest ecosystems in the southern United States. The large spatial scale and complex interactions make traditional experimental approaches difficult. Yet, the current progression of climate change science offers new insights from recent syntheses, models, and experiments, providing enough information to start planning now for a future that will likely include an increase in disturbances and rapid changes in forest conditions. Climate Change Adaptation and Mitigation Management Options: A Guide for Natural Resource Managers in Southern Forest Ecosystems provides a comprehensive analysis of forest management options to guide natural resource management in the face of future climate change. Topics include potential climate change impacts on wildfire, insects, diseases, and invasives, and how these in turn might affect the values of southern forests that include timber, fiber, and carbon; water quality and quantity; species and habitats; and recreation. The book also considers southern forest carbon sequestration, vulnerability to biological threats, and migration of native tree populations due to climate change. This book utilizes the most relevant science and brings together science experts and land managers from various disciplines and regions throughout the south to combine science, models, and on-the-ground experience to develop management options. Providing a link between current management actions and future management options that would anticipate a changing climate, the authors hope to ensure a broader range of options for managing southern forests and protecting their values in the future.
