Resumo Neste trabalho apresentamos uma análise das ações de divulgação e popularização da ciência na Fiocruz a partir de duas perspectivas. O estudo tem por objetivo investigar como se organiza um sistema de divulgação e popularização da ciência em uma instituição científica de grande porte e como esse sistema se articula com seu discurso institucional. Além de fazer uma breve revisão da evolução do tema na história da Fiocruz, realizamos um levantamento de como o mesmo tem sido tratado nos documentos oficiais de planejamento. Com o mapeamento das ações realizadas em 2015 e 2016, foi possível compreender melhor esse universo e classificá-lo de acordo com suas características junto ao público.

Abstract An analysis is presented of actions taken by the Brazilian research institution Fiocruz for the communication and popularization of science, from two perspectives. The aim was to investigate how a system for the communication and popularization of science is organized at a large scientific institution and how it is articulated with the institutional discourse. A brief review is presented of how the topic has developed over the history of Fiocruz, followed by a discussion of the way it has been addressed in its official planning documents. The science communication/popularization actions undertaken in 2015 and 2016 were mapped out and classified according to how they interact with the public, giving a better understanding of this area.

In this transversal study, factors related to infection with and transmission of Schistosoma mansoni were explored. Based on stool examinations of two Kato-Katz smears of a single sample, the prevalences of schistosomiasis and geohelminths were established. In a multivariable analysis, sets of demographic, socio-economic and water contact pattern variables were tested for strength of relation with infection. Males presented a 3.39-times higher risk for infection than females. The age groups between 10-19 years and 20-30 years showed risks of infection 7.1- and 7.5-times higher, respectively, than the control age group between 0-10 years. Individuals practicing leisure activities had a 1.96-times higher risk than those without these activities. The malacological survey identified snails of the species Biomphalaria glabrata, Biomphalaria straminea and Biomphalaria tenagophila. Two exemplars of B. glabrata (0.53%) proved positive for S. mansoni. The socio-economic improvements observed in the locality suggest a protective and preventive effect towards infection with schistosomiasis, which requires further investigation with a longitudinal and more detailed study design. Considering our findings, a proposal for an integrated control program should be based on two pillars: one horizontal, which involves social empowerment and health education, and another more vertical, which delivers treatment and infrastructure improvements.
