Pandemics are often associated with viruses and bacteria occurring in wildlife in natural environments. Thus, diseases of epidemic and pandemic scale are mostly zoonotic, some of which include AIDS, Zika Virus, Severe Acute Respiratory Syndrome (SARS), and COVID-19. The book seeks to explore the documented history of pandemics and various epidemics which have the potential of turning into pandemics with the warming climate, pollution, and environmental destruction.The book covers some of the most essential elements of the diseases of pandemic nature and their relationship with the environment.Environment as a reservoir of human diseasesClimate Change: Emerging Driver of Infectious DiseasesOccurrence and Environmental Dimensions of Specific Pandemics and EpidemicsPandemics, Environment, and Globalization: Understanding the Interlinkage in the Context of COVID-19Climate Change and Zoonotic Diseases: Malaria, Plague, Dengue, EncephalitisTuberculosis: An old enemy of mankind and way to next pandemicLassa fever in Nigeria: case fatality ratio, social consequences, and preventionThere are cases where scientists fear that there are many epidemics which have the potential of turning into pandemics, if not paid attention to, and measures not being taken to control these occurrences. This book attempts to provide integrated risk assessment on COVID -19 like pandemics. It covers fundamental factors of global disease outbreaks through the complexity and severity of consequences. Information collated in this book would help in the design of mitigation measures, including behavioral changes that would prevent the emergence of such pandemics, thus protecting human life and minimize losses incurred due to diseases of such magnitude.
