The present study focuses the co-construction of narratives of Vila Rosário Institute community health workers’ and residents in the tuberculosis treatment program in Vila Rosário area in Duque de Caxias, Rio de Janeiro. The objective consists in investigating the role of those narratives in the interactions. The research is supported by FAPERJ and is linked to the research projects Vila Rosário: Discursive Practices of the community and social representation in the prevention and education to combat tuberculosis and Vila Rosário: The Institutional and Professional Discourse for the prevention and education to combat tuberculosis. The research is of qualitative and interpretative approach, with theoretical orientation by Interactional Sociolinguistics, Narrative Analysis and theories of agency and performance. The methodology lies on ethnographic basis with micro analysis orientation. The corpus data were generated from work meetings at Vila Rosário Institute and during accompaniments to visits made by the workers to residents, with audio recordings and field notes. The results of the workers’ narratives show elaborate performances, shared narratives, agency through doing and tension between tuberculosis treatment and the residents’ social reality. Residents’ narratives, co-constructed with the agents, also indicate agency, but with passivity and subordination, and the non-access to tuberculosis treatment as one of the many problems they face. This work seeks to contribute with studies about poor communities and illnesses, emphasizing the importance of narratives as an analytical and reflexive tool.
