Of about 2000 hospitalized children whose stools were examined routinely, 18% were infested with Trichocephalus trichiurus. The heavy infestations (over 30,000 eggs/ cc.), which consistently produced diarrhea and dysentery, were most common in children 2 to 4 years of age. A significant correlation existed between worm-burden and incidence of amebiasis.
A successful technic for the treatment of trichocephaliasis is described. The importance to the clinician of measuring worm burden is emphasized.
