Understanding how the American Indian perceives the health and medical programs of the Anglo culture is the key to the United States Public Health Service in being able to raise the Indian's level of health to that of the general population. Vast differences between the American Indian, as represented by the Navajo, and the non-Indian are found in language, customs, cultural patterns, health concepts, and social organizations; therefore, overcoming cultural differences as well as increasing health facilities will be necessary. A long-term health education campaign in schools and community is essential before the Navajo individual will be able to perceive Anglo medicine in a manner which will contribute to the maintenance of his own health.
