High rates of human immunodeficiency virus (HIV) infection among jail
and prison inmates suggest that HIV prevention efforts should focus on
incarcerated populations. Overcrowding, the high prevalence of inject
ion drug use, and other high-risk behaviors among inmates create a pri
me opportunity for public health officials to affect the course of the
HIV epidemic if they can remedy these problems. Yet, along with the o
pportunity, there are certain obstacles that correctional institutions
present to public health efforts. The various jurisdictions have diff
ering approaches to HIV prevention and control. Whether testing should
be mandatory or voluntary, whether housing should be integrated or se
gregated by HIV serostatus, and whether condoms, bleach, or clean need
les should be made available to the prisoners, are questions hotly deb
ated by public health and correctional officials. Even accurate assess
ment of risk-taking within the institutions leads to controversy, as a
sking questions could imply acceptance of the very behaviors correctio
nal officials are trying to prevent. Education and risk-reduction coun
seling are the least controversial and most widely employed modes of p
revention, but the effectiveness of current prevention efforts in redu
cing HIV transmission in this high-risk population is largely underter
mined.
