Dissemination is the targeted distribution of health information and intervention materials to specific audiences. (Interventions are programs, [Page 363]products, or strategies designed to alter health behaviors, reduce health risks, or improve health outcomes.) The overall goal of dissemination is to increase audiences' awareness of information or use of evidence-based interventions.

Health researchers are continually identifying new ways to help prevent and treat disease and enhance health. However, these innovations must be disseminated so research findings can have real-world impact. Health communication is integral to dissemination because it is through communication that awareness of new health information and interventions can be widely and effectively spread.
