A new world with AIDS--health promotion as a catalyst for change.

Preventing the acquired immunodeficiency syndrome (AIDS) requires an unprecedented response from public health professionals, particularly educators and communicators involved with health promotion. Health promotion is defined and discussed in the light of recent experience in a broad range of public health programs. Increased sophistication is needed in the application of social science within health promotion and increased facility in mobilizing cross-sectorial resources to achieve public health objectives and generate confidence in approaching AIDS prevention.
