Preface

The authors were inspired to write this book by a vision to provide the basic and core information regarding the novel and life-threatening coronavirus namely 2019-nCoV causing COVID-19, of which the entire world was completely unaware.

The COVID-19 pandemic outbreak has evidenced us to be an astounding catastrophe inflicting billions of lives around the globe. To date, it was reported that the third highly pathogenic human Coronavirus disease is COVID-19, which has posed a severe and serious threat to the entire world's socioeconomic, medical, and public health infrastructure.

Considering the present scenario, this book contains eleven chapters on different aspects related to COVID-19 and 2019-nCoV summarising what we have hitherto learned in the following key areas of virology, epidemiology, aetiology, damage response framework, pathophysiology, and diagnosis of COVID-19.

Several candidate-repositioning drugs have been proven with a record of both safety as well as efficacy profiles which have been widely used in some countries during the pandemic situation against 2019nCoV. Due to their pharmacological role and mechanism of action, some phytopharmaceuticals and immunomodulators are efficacious against 2019-nCoV and might be finding potential to combat COVID-19; all of which are discussed in this book in detail. This book also provides deep insights into the repurposed drugs, pharmaceutical intervention strategies, various treatments, clinical and research approaches, all authorised vaccines and nanotechnology tools that may fill the research gaps for the current COVID-19 management and future pandemic outbreaks of newly emerging 2019-nCoV variants.

To manage COVID-19 and curb the global spread of 2019-nCoV, knowledge of all of the above aspects is required. Hence, we compiled all of these elements into one book as separate chapters to present a valuable resource of information on COVID-19 for all of those who are involved in this coronavirology field.

This book in essence provides a grass-root level of knowledge about COVID-19 and 2019-nCoV. It is also a manual to guide future coronavirology scientists assisting them with future research ideas and approaches to combat new variants of 2019-nCoV as well as future outbreaks of coronaviruses.

We hope that you enjoy this book and find it useful.
