Preface

In this third year of the SARS-CoV-2 pandemic responsible for Covid-19 diseases worldwide, the scientific studies and reviews focused on this virus and related variants are still crucial. This book, corresponding to the third volume of the e-book series on ‘Coronaviruses’, brings together some essential data regarding the origin, pathology and chemotherapeutic drugs to treat coronavirus infections. It consists of six chapters concerning (1) the bat’s coronaviruses in the world (chapter 1 by Karin Correa Scheffer et al.), (2) the hospital challenges during the Covid-19 pandemic (Chapter 2 by Salman Zarka et al.), (3) the pro-inflammatory and thrombotic manifestations and the therapeutic options of Covid-19 (chapter 3 by Mradul Kumar Daga et al.), (4) the common and rare dermatologic manifestations registered in Covid-19 patients (Chapter 4 by Amin Daemi et al.), (5) the circulating biomarkers of cardiopulmonary disturbances in Covid-19 (chapter 5 by Amin Daemi et al.), and (6) the aspects of pathology and pathogenesis of coronavirus infection (Chapter 6 by V.A. Zinserling et al.). This new volume actually compiles the most important data/information on SARS-CoV-2 and associated Covid-19 diseases. It is therefore of clear value for all the researchers working in these research fields, and for the clinicians dealing with a growing number of persons with Covid-19 and/or suffering from post-Covid sequelae, referred to as long Covid (data from 23^rd November 2022: 644 million cases of SARS-CoV-2 infection worldwide, with 6.6 million deaths).
