Preface

Epidemics and pandemics have been frightening the human chase again and again. SARS, H1N1, Ebola, and more have exposed their real face in the past, but with every such outbreak. The coronavirus outbreak came to light on December 31, 2019 and this COVID-19 pandemic is the defining global health crisis of our time and the greatest challenge. As the global Covid-19 pandemic evolved, several countries faced a surge of acute and critically ill patients but had limited resources of space, staff, and stuff. In a relatively short period of time, the new coronavirus was recognized; the travel on COVID-19 has grown exponentially, from a single scientific report to over a few thousand publications, across numerous disciplines. The universality and clinical implications of our observations require further research to define. This pandemic has provoked an extraordinary requirement for digital health technology solutions and has exposed victorious solutions such as population screening, the pathway of the infection, projecting the use and allocation of resources, and designing targeted responses. In this scenario, the thrust area of research towards this “AN EPIDEMIOLOGICAL UPDATE ON COVID -19” is welcomed.

This edited book chapter has been fully revised and updated to suit the requirement of the readers and highlights the comprehensive overview of recent novel coronavirus infections, their biology and associated challenges for their treatment and prevention of novel Coronavirus Disease 2019 (COVID-19). A thoughtful of the topics covered in the book is very important in the context of designing strategies to protect the human race from further sufferers and harm due to SARS-CoV-2 infection-causing COVID-19.

The target audience will include advanced science, medical, pharmacy and nursing students and all the researchers. On behalf of all the chapter authors, we hope to spread the word that this book emphasizes all the thrust areas of COVID-19.
