Considerations are first presented about medical educat ion in general and about the SENAR/SP Institution and its attributes in the so-called informal education in topics ofPreventive Medicine, Professional Training and Social Prornotion. Thus, from the viewpoint of the concepts of Preventive Medicine, emphasis is placed on Reproductive Health, Basic Nutrition, Oral Health and Sanitation . Other topics will be inc luded such as Prevention of Disease in the Third Age of Men and Women, Disease Transmitting Insects, Prevention of Acute Infections, and Occupational Health. The model of transmission of fundamental knowledge to the target (rural) population is based in the following chain: professor of medicine, instructor, and multiplying health agent. The activities planned in the line of health rigorously follow the stages established in the methodology. Some indicators are presented to portray the health profile of the three pilot municipalities which were the beneficiaries of the actions of the Program during its initial stage. All the topics treated in the course of the trainning of instructors and multiplying health agents were presented jointly. We discuss the major topics in the elaboration of the actions, including the role of each link in the chain for the transmission of knowledge. We also discuss the difficulties and benefits of the implantation and execution of the preventive health activities in the rural area. The so-called multiplying agents represent a fundamental link between the professor of medicine and the target population, and should be recruited, selected and trained with the utmost ability.
