As the fight against leprosy in Brazil, particularly in the state of Maranhão, is singled out for analysis, this paper discusses the different medical and 'profane' conceptions of the disease, in addition to the proposals of public health intervention, always challenged by rival doctrines or convictions about contagion, diffusion, and treatment. The changing epidemiological, medical (i.e., the practices of isolation), social, and cultural views (particularly the stigma associated with the notions of sin, purity and danger) will help the search for singularities in Maranhão, the state's main 'sanitarians', political actors, and institutions, as well as for common historical elements, among Brazilian and other populations experiencing the disease.
