After the very positive reception to the article entitled "Cual es el papel del psic logo ante el nuevo Coronavirus?" ("What is the role of psychology in the face of the new Coronavirus?") published in La C tedra Abierta de Psicol gia y Neurociencias on 12th February 2020, and the general interest evoked amongst fellow psychologists and other people with an interest in psychology, I have decided to produce this book, which addresses the subject of the psychological perspective in times of a pandemic. Despite the fact that information concerning health crises such as Coronavirus is very recent and in some cases quite changeable, I am going to present a work based on current data sourced principally from scientific publications, and which will include, from the same sources, statements from various experts. A book accessible to all those who wish to delve into the psychological aspects of a mass phenomenon in times of a health crisis, as in the case of Coronavirus.
