Risk-Based HIV Testing at Los Angeles County Men's Central Jail.

Incarcerated populations tend to be disproportionately affected by HIV and sexually transmitted infections (STIs), and men who have sex with men (MSM) are an especially high-risk subset of these populations. Despite the Centers for Disease Control and Prevention's recommendations for universal HIV screening, a lack of resources and high inmate turnover make it difficult to implement such guidelines in jails. From September 2013 to May 2016, the Infection Control Unit of the Los Angeles County Jail used existing resources to implement a voluntary, risk-based HIV educational and screening program targeting MSM inmates during early incarceration. The results revealed a high percentage of previously unknown HIV infections (8.5% = 57 of the 671 tested) and some unknown non-HIV STI cases. In the absence of resources for universal HIV screening, the risk-based approach is a sustainable and cost-effective approach for improving HIV surveillance in the correctional setting.
