Program Guidance

The purpose of this website is to provide information to CBOs and health departments that are or will be implementing CRCS (formerly known as Prevention Case Management or PCM) – an intensive, individual level, client-centered risk reduction intervention for people at high risk for HIV infection or transmission.

The CDC Division of HIV Prevention is pleased to provide a basic guide to the cost-effectiveness analysis of prevention interventions for HIV infection and AIDS.

Individual-level and group-level risk reduction interventions are effective in increasing condom use and reducing unprotected sex. These types of interventions, however, focus on an individual’s personal risk and do not address barriers beyond the individual, such as not having access to condoms.

We have many tools to diagnose, treat, and prevent HIV, but sometimes these services don’t reach people who need them most. HIV cluster detection and response (CDR) allows public health professionals to identify and respond to rapid HIV transmission. Responding includes identifying and closing gaps in prevention and care services for affected communities. Because rapid transmission can affect people beyond the identified cluster, responding at the individual, network, and systems levels is important.
