Objective To access the prevalence situation of three species intestinal nematodes infection in rural area of Yangxin county of Hubei province, so as to provide the basis for prevention and treatment. Methods The eggs of intestinal nematodes were detected qualitatively with saturated salt solution floating method. Results Of 1244 detected residents, the infection rates of Ascaris lumbricoides, Hookworm and Trichuris trichiura infection were 14.31%, 24.28% and 2.97% respectively. The highest infection rates of Ascaris lumbricoides and trichuris trichiura were in the group of <7(26.32%and7.37%),the highest infection rate of hookworm was in the group of 41~50(36.22%). Conclusion The prevalence of intestinal nematodes (hookworm particularly) was still serious in the village of Yangxin county of Hubei province.
