Since the identification of the first cases of the coronavirus in December 2019 in Wuhan, China, there has been a significant amount of confusion regarding the origin and spread of the so-called 'coronavirus', officially named SARS-CoV-2, and the cause of the disease COVID-19. Conflicting messages from the media and officials across different countries and organizations, the abundance of disparate sources of information, unfounded conspiracy theories on the origins of the newly emerging virus and the inconsistent public health measures across different countries, have all served to increase the level of anxiety in the population. Where did the virus come from? How is it transmitted? How does it cause disease? Is it like flu? What is a pandemic? What can we do to stop its spread? Written by a leading expert, this concise and accessible introduction provides answers to the most common questions surrounding coronavirus for a general audience.

‘With all the technology and medical knowledge of the 21st century a pandemic virus has defeated us. This book tells us why and how that could happen and what we can do about it. And as a bonus we get a comparison with the 1918 pandemic Flu. All this wrapped up in a clear, understandable and interesting way. We learn what is happening to us now and how to better prepare for the future.'

'Raul Rabadan has written an essential book for the first pandemic of the 21st century, COVID19 caused by SARS-CoV-2. It’s a wonderfully concise and accessible explanation of everything you want to know about the virus, the disease, and the outbreak. If you want to learn what is a coronavirus, how the outbreak started, what are the therapeutic options, and much more, I highly recommend this book. Professor Rabadan explains viruses in a way that is accessible to all.'

‘A much-needed primer that offers basic information … What Understanding Coronavirus does very well is clarify virology and epidemiology basics. Asking how quickly the virus spreads means explaining the basic reproduction number R0 and concepts such as 'flattening the curve' and herd immunity that everyone has been confronted with. It explains the symptoms, the typical course of the disease, how deadly it is, and that, yes, children and young adults get infected too, but their symptoms are usually less severe … Understanding Coronavirus overall provides a lot of relevant information in a very readable and concise format. And at this price, you cannot really go wrong.’
