South Carolina is the last state in the country to still segregate HIV+ inmates into separate areas, away from HIV- inmates. The last three states in the nation to continue with this policy were South Carolina, Alabama, and Mississippi. Alabama’s policy was deemed unconstitutional just last year, after a court battle. Mississippi changed its policy in 2010 after activists and attorneys pressured the Department of Corrections commissioner Christopher Epps to rescind the policy (which he did, very much to his credit).
Segregating HIV+ inmates is bad policy for some pretty obvious reasons.
