Abstract
Objective: To report the experience of nursing undergraduate students in extension actions for the Sexually Transmitted Infections (STI prevention. Experience report: The project is composed of nursing undergraduate students at the Federal University of Bahia. In order to subsidize the actions carried out, there was theoretical training, in which weekly discussions were held, promoting a greater approximation of the executing team with the theme. The extension actions were based on active methodologies and carried out in the most different spaces between streets, schools and university campuses. During the approaches, educational materials on STI were made available, prevention supplies such as condoms and lubricating gel, beyond addition to HIV testing. The training that preceded the activities provided an opportunity to expand knowledge and exchange significant experiences. It was possible to identify that many people adopt an invulnerability behavior. On the other hand, there were also positive feedback as expressions of interest, curiosity and reports of experiences on the subject. The extra-wall actions prevention implemented were perceived as an important mechanism for coping with STI. Final considerations: Talking about STI is still taboo in society. Extension activities are essential for strengthening the link between academia and the community.
