Border HIV prevention study targets drug users with community approach

This study adapted and tested a community-based HIV prevention program for people who inject drugs living along the U.S.-Mexico border. Researchers worked with 840 participants to understand how violence and stigma affect HIV risk, then used social networks, peer education, and community events to reduce risky behaviors like sharing needles and having unprotected sex for drugs. The goal was to lower the chance of getting HIV in this high-risk population.
