The prevalence of intestinal helminths was studied in students enrolled in the upper elementary grades in McCreary County, Kentucky in 1968. The over-all rate was 22.1% of those submitting specimens. Hookworm was the most common parasite found. occurring in 14.8% of the specimens. Class rates ranged as high as 53.8% for all parasites and 36.4% for hookworm. Of those with a previous history of “worms,” 31.0% were positive for helminths on examination of a single specimen. The rate for those having a city water supply for the home was one-half that for those who did not. The rate for those with an indoor toilet was one-third the rate for those without an indoor toilet. The water source and type of toilet appear to be of even greater importance in the case of hookworm infection.
