This book is divided into 5 chapters, each dealing with a different aspect of the management of this unprecedented health crisis. The first chapter is devoted to issues of respect for constitutional law and fundamental freedoms in the countries examined focusing on emergency measures. The second chapter deals with Covid management in a comparative study, taking into account intercultural aspects and influences in several areas of economic and social life. The third chapter looks at the secondary effects of pandemic protection measures. These effects have not always been sufficiently taken into account in government decisions. It is only by looking back that we can analyse these consequences. Life during the pandemic was largely reduced to digital life. To some extent, this digitisation has allowed activities to continue, but it has not been without risk. Chapter 4 looks at data protection during this period, the role of the media and the reorganisation of working and industrial relationships. Finally, the last chapter deals with health issues, which were at the heart of Covid's management.
