Abstract

Summary

A survey for intestinal helminths among school children in three Eastern Kentucky counties has revealed prevalence rates of Ascaris to range from 22% to 60%, depending on the population sampled. Trichuris rates similarly range from 6% to 67%. Hookworm and Strongyloides infections are rare but continue to exist.

No significant interference with growth or hematocrit levels is demonstrable in those children infected with parasites although there is a suggestion of such a relationship.

Eosinophilia as a reflection of parasitism has again been confirmed.

The historical trends in the parasite problem in Eastern Kentucky suggest that, although the wearing of shoes may have contributed to the diminution of hookworm as a public health problem, no major impact on Ascaris and Trichuris has yet been made, presumably largely because of the failure to successfully alter environmental sanitation.
