Preface

In the 21st century, the world has witnessed several waves of severe viral infectious disease outbreaks, including but not limited to the COVID-19 pandemic. Viral outbreaks are the major cause of infectious disease burden, placing substantial economic pressure on countries with low and lower-middle incomes. Rapid progress in urbanization in these countries and increased population density have created newer prospects of viral outbreaks and transmissions. Therefore, understanding the global spatial and temporal dispersal of newer viruses as well as the challenges that come along with them is vitally important.

*Viral Outbreaks - Global Impact and Newer Horizons* provides a comprehensive overview of the major viral global outbreaks. It discusses epidemiology, immunopathogenesis, viral genomics, diagnostic approaches, and antiviral pharmacology to combat these viral infections. This book is a useful resource for academics, policymakers, researchers, and students.

I wish to acknowledge all the authors for their valuable contributions. My research fellows and students are central to all my research and academic work. They are the motivating force behind anything constructive I do. They are truly brilliant and have a bright future. I would like to express my gratitude to my mentors, teachers, and students. I would also like to thank my colleagues, family, and friends who offered encouragement and support during my work on this book. A happy environment at home is essential for any kind of growth, and I thank my family, especially my wife and children, for the same.
