Contagions: Domains, challenges and health devices

This article aims to understand the domains and uses of the various conceptual frameworks of contagion, its modalities and effects, in its different acceptations and historical contexts, as an expression of the process of interdependence between the stances and the different viewpoints of diverse actors involved with multiple scientific, moral, social and political challenges. Another objective focuses on understanding the process of collective management of contagion, disease and health, in which prevention is a critical element of its objectives and justifications, its discursive order and its practical activities.
