The Health Educator Program provides for indigenous personnel as communication links with residents of urban slums; they visit the homes and teach basic principles of cleanliness and health. Frequently their work involves relationships between landlord and tenant or cooperation with other city departments. A pioneer program in Chicago was so successful as a communication system that the concept of Health Educator Aides is expanding in other directions. The person-to-person approach is an important but simple approach to ghetto problems but the program needs the support of overall city efforts and should be administered by a permanent community agency.
