Over the past five years the Tanzanian-Norwegian AIDS Project (MUTAN) has assisted the National AIDS Control Programme in creating and testing innovative HIV/AIDS educational programmes. These programmes, designed to reach a variety of target groups, have been implemented throughout the Arusha and Kilimanjaro regions and include: public meetings, intensive courses, information centres, radio programmes and school-based programmes. A recent survey of 996 participants (15-54 years old) was designed to assess public exposure to HIV/AIDS information. A total of 72% of the participants reported having heard about AIDS on the radio, 74% having read about AIDS in newspapers, and 52% having heard about AIDS from a health worker during the previous month. Furthermore, 26% had listened to MUTAN's weekly radio programme at least once. 31% knew of MUTAN's information centres, and 15% had visited one of these centres. The results indicate that large proportion of the population is receiving in-depth HIV/AIDS information. It is recommended that future work concentrate on how to reach people with no or little formal education, young adults and women.
