Objective To understand the prevalence situation of geohelminthes disease and the influ-ence factors,to grasp the prevalence regulation and forecast tendency,and provide the scientific basis for for-mulating control measures and evaluating control effect.Methods Residents over 3 years old in the surveil-lance sites were selected as subjects.The Kato-Katz method（three slides per stool sample） was used to count geohelminthes eggs;and the cellophane tape anal swab test was applied to detect pinworm infection of chil-dren from 3 to12 years old.10 households was selected randomly,and the soil samples of four sites of each household,the vegetable gardens,lavatories,yards and kitchens,were collected and observed the contamina-tion of geohelminthes.Results Of 1019 residents with stool examination,there were 59 persons infected with the roundworm,uncinaria,whipworm or pinworm.The infection rate of geohelminthes was 5.99%,among which the infection rate of pinworm was the highest（14.10%）,and that of roundworm was the second（3.53%）.43 soil samples were examined,and the detection rate of roundworm in stool samples from yards,kitchens,vegetable gardens,lavatories was 63.63%,9.09%,54.55% and 63.63%,respectively.Conclusion The infection of geohelminthes in Chongqing took on a decline tendency.
