Abstract
This article gathers reflections on the proposal presented by the Costa Rican Demographic Association to the Social Protection Board entitled “Promotion of Sexual Health, prevention and detection of hiv in young people in the Great Metropolitan Area of Costa Rica”, executed during the year of 2017. The theoretical and practical foundations of the
project, as well as the contextual national references on sexual and reproductive rights in the prevention and detection of hiv/aids, are systematized and described through the participant observation methodology. The theoretical approach is critical intersectional feminism, from which we create reflections and contribute to the work of contemporary feminist movements, specifically in the integration of multisectoral and anti-class politics.
