ABSTRACT
Hookworm infection has traditionally been highly endemic to Anhui Province, China. Zhongzhou village in southwestern Anhui was identified as an endemic focus of infection caused by the hookworm Ancylostoma duodenale. This species was found to predominate over Necator americanus in ratios ranging from 351 based on the recovery of third-stage infective larvae (L,) to 211 based on the recovery of adult hookworms after anthelmintic chemotherapy. The overall prevalence of Ancylostoma infection in Zhongzhou was 33.2% with a greater prevalence among males. Unlike the age-associated prevalence patterns for N. americanus in Hainan and other southern Chinese provinces that show increasing prevalence with age and the highest prevalence among the elderly, the age-associated prevalence for A. duodenale in Zhongzhou exhibited a peak in middle-aged adults with subsequent decline. The age-associated intensity pattern exhibited a similar trend although the most of the hookworm infections were light or moderate infections as defined by quantitative egg counts.
