After the very positive reception to the article entitled “Cual es el papel del psicólogo ante el nuevo Coronavirus (COVID-19)?” (“What is the role of psychology in the face of the new Coronavirus (COVID-19)?”) published in La Cátedra Abierta de Psicológia 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 COVID-19 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 COVID-19.
