Abstract

The presence of tinea capitis in abundance in the semitropical delta of the Rio Grande river has considerable geomedical implications.

The permanent population of "The Valley" consists primarily of native Texans of Mexican descent and transplanted Midwesterners. There is also a liberal sprinkling of natives of Mexico and native Texans of European descent, particularly German and Scotch-Irish. Negroes form less than 1% of the population. It is estimated that 50%-60% of the population is of Mexican descent.

It also has other transient population of special note in the form of two Air Force bases, numerous border patrolmen, considerable oil and gas activity—with its transient crews and families, and a burgeoning tourist trade. The latter, however, at present, is composed chiefly of senior citizens who have little contact with the permanent residents, being seasonally congregated in tourist facilities for the most part.
