Abstract

Objective To analyze the prevalence of soil-transmitted nematode infections in Xiangcheng District of Fujian Province in 2011.Methods Dazai village of Xiangcheng District of Zhangzhou City was selected in 2011.Kato-Katz method was used to detect the eggs of intestinal helminthes and cellophane tape was used to detect the eggs of pinworm among children age 3 to 12.Soil samples in the vegetable garden,orchard and other plantations were collected from 15 families and hookworm larvae in the soil were isolated,cultured and identified.Results A total of 1022 persons were detected.146 persons were infected with soil-transmitted nematodes and the infection rate was 14.29％.The infection rate of hookworm was 10.76％(110/1 022).Ascaris and Trichuris were not found.115 children were detected among them 36 were found infected with pinworm,the infection rate was 31.3％.10 soil samples from the vegetable garden were examined and 6 of them contained hookworm larvae.5 soil samples from the orchard were examined and 4 of them contained hookworm larvae.All of them were identified as New-World hookworm.Conclusion Comparing with the results of the first phase of the five-year surveillance results,a decreasing trend of the soil-transmitted nematode infections was revealed in 2011,but a relatively high rate of hookworm infection in children was noticed.
