Intestinal nematodes in the United States.

Abstract

Intestinal nematodes other than pinworms are often thought of in this country as unimportant or novel. Yet, in many low-income rural communities in the Southeast, half or more of the children have infection with Ascaris lumbricoides or Trichuris trichiura or both1 2 3 4 5; and in urban areas, immigrants from tropical countries constitute a substantial population with a high prevalence of these and other parasites. In any population in which intestinal nematodes are common, serious morbidity may occur.No data are available on the overall prevalence of intestinal nematode infection in the United States.1 In 1972 Warren6 attempted to update Stoll's7 1947 . . .
