In 1999, the Centers for Disease Control and Prevention and the Health Resources Service Administration (HRSA) partnered to provide funding in order to manage a corrections-to-community HIV discharge planning and case management demonstration project. The States of California, Florida, Georgia, Massachusetts, New York, and New Jersey, and Cook County, Ill, were selected as demonstration sites. This demonstration project assumes that individuals who engage in high-risk health behaviors are hard to reach with public health services in the community, and through cooperative partnerships various programs may be implemented in order to provide disease prevention messages, STD screening, HIV counseling and testing, and hepatitis B and C prevention, treatment information, and services. Following a discussion concerning the relatively low cost of funding the programs within the demonstration project, the article indicates that the demonstration program’s various successful projects validate the importance of strong corrections-public health collaborations in order to effectively combat communicable diseases.
