We consider that the professional fields of education, health and health education have practices that govern the conduct of individuals so we developed a reflection that aims to contribute towards problematizing professional training in these fields. Based on a testimony extracted from an educational video that presents the theme of prejudice and compulsory isolation for people with Hansen's disease, we discuss the peculiarity of the exclusion mechanisms, as postulated by Michel Foucault, and present examples that show to what extent these mechanisms have still functioned recently with those who have the disease in Brazil. Revisiting the events that led to the change of the disease's name - from leprosy to Hansen's disease - we analyzed the struggle of a Brazilian doctor against prejudice, making an ethical reflection following the clues of the Foucaultian investigations on the theme of the constitution of the moral and active subject, the sovereign of himself.
