Examination of some 6000 Navajo children in their schools in the Shiprock, New Mexico area between 1975 and 1977 yielded an overall prevalence of trachoma of 2.4%. The prevalence was highest for high schoolers (3.8%) and lowest for preschoolers (2.3%). These prevalences are lower than those found (6.0%) for Navajo schoolchildren in the Gallup, New Mexico area 8-9 yr previously.
