Abstract:
Due to the increased HIV-incidence, there has been recently a lively discussion in Switzerland about the issue of HIV/AIDS and Sub-Saharan migration. In addition to a pilot intervention project about HIV/AIDS prevention among Sub-Saharan migrants in Switzerland, in-depth interviews aimed at revealing insight from the migrants' perspectives and providing information for effective HIV prevention. It is important to mention that HIV prevention in this research project is also understood as secondary and tertiary prevention. HIV positive persons from this population group should be given a voice, since discussion has recently focused on the increased incidence amongst migrants from Sub-Saharan Africa. This article will address the question of how we accessed interviewees from this target group, and we will describe the many challenges met and overcome in this part of the research process.
