Fundación Margen collaborates with a project that aims to monitor government policies on HIV/AIDS and STIs.

The organization member of the network has taken the design and implementation of field surveys on female sex work, to draft a report on how public policies on sexual health are being implemented in different sectors of the region, particularly with children, youth, prisoners, transgender women and female sex workers.

In a collaborative project with Fundación Savia and various organizations, the Observatory of Public Policies on Health was formed, which aims at monitoring government policies on HIV/AIDS and STIs, specifically, in sex trade.
