[The nursing role in the face of health inequalities].

Social inequalities in health refer to differences in health status between people or groups of people, linked to factors that are particularly social, unequal and considered morally or ethically unacceptable. These may be major differences in life expectancy, or in the greater likelihood of being a carrier of disease, depending on the social group to which one belongs or the territory in which one lives. Accentuated during a health crisis, they are, however, avoidable.
