“…Researchers explained this difference by the disproportionate number of offenders who, before their incarceration, had less access to health care and engaged in intravenous drug use and unprotected sex at a rate higher than the noninstitutionalized population (Alarid & Marquart, 1999;Cotton-Oldenburg, Martin, Jordan, Sadowski, & Kupper, 1997;Macalino, Vlahov, & Sanford-Colby, 2004;Rich, Dickinson, & Macalino, 1999;Spaulding et al, 2002). While the transmission rate was significantly lower in prison than on the streets, prisoners continued to engage in unsafe sexual practices and tattooing behaviors while incarcerated which placed them at risk for contracting HIV during their sentence (Krebs, 2006;Krebs & Simmons, 2002;Wohl, 2006). Given the highly transient nature of the criminal justice system, when county jails were factored in, an estimated one out of four people living with HIV passed through a jail or prison correctional facility in a single year (Spaulding et al, 2002).…”
