Foreword

The connection between human health, animals, and the environment has been widely recognized as important for the ecosystem we inherit and intend to improve for the generations to come. This of course is not a responsibility of a region or a country, rather its responsibility of all of us. Efforts have to be collaborative and transboundary in approach. Of the many types of challenges, respiratory diseases have emerged as a real threat in the recent past. Scientists have been working to reduce their load and easily spread it from animals to human beings. Newly emerging respiratory diseases such as severe acute respiratory syndrome-coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS), and severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) posing a serious threat to the human population and reported in the year 2003, 2012, and 2019, respectively.

This book is very relevant in this connection. The volume-1 of this book consists of three key modules. The first module provides clearly defined progression and entry of SARS-CoV-2 to the human population. The learning outcomes of this module are developing knowledge, skills, and competencies in scientists, students, employers, and human resource specialists. The other modules of this book focus on developing a detailed set of guidelines regarding epidemiology, genetic alteration, a structural protein, quantitative analysis, and diagnostic approaches of SARS-CoV-2 and will give step-by-step awareness to the researchers about SARS-CoV-2. This book will be adopted to give reliable knowledge to all scientists globally. I hope that this book will be distributed widely in Pakistani higher institutions in the near future for thorough implementation at all levels of postgraduate studies.
