TL;DR: FSW-IDUs had higher STI levels, engaged in riskier behaviors and were more vulnerable to having unsafe sex with clients compared to other FSWs, indicating that this subgroup is an important bridge population requiring focused prevention.

TL;DR: Culturally appropriate interventions are needed to identify and treat ulcerative sexually transmitted infections and reduce HIV risks associated with stimulants among FSWs in the Mexico-US border region.

TL;DR: Factors operating in both the micro-social environment and policy environment predominated as factors associated with risk of HIV infection, rather than individual-level risk behaviors.

TL;DR: Individual, social, and environmental factors were independently associated with HIV infection among IDUs in Tijuana, Mexico, suggesting the need to intervene not solely on individual risk behaviors but on social processes that drive these behaviors, including problematic policing practices.

TL;DR: RDS was an effective method to rapidly recruit IDUs in these cities, and although the frequency of HIV was low, syphilis prevalence was high, particularly in Tijuana, suggesting that further validation of RDS is necessary.
