Every group was usedχ2 test for the detection rate. The detection rates between different groups were compared with the χ2 test. Results The detection rate of ascaris eggs was 91.67%, the detection rate of live fertilized ascaris eggs was 65.83%. Non - sanitary latrine utilization rate was 55.39%. The proportion of non - sanitary latrine in the surveyed households was 44. 61%, and the proportion of sanitary latrine was 55.39%.
