Investigation on human Ascaris infection in Qinghai Province in 2015

Abstract

Abstract:

The aim of this study was to further understand the status of Ascaris infection in humans and facilitate effective control of ascariasis in Qinghai Province.The cluster-stratified sampling method was used to detect worm eggs in 53 investigation points in 17 counties(cities) from May to September, 2015.The intestinal helminth eggs in fecal samples from residents were detected by the Kato-Katz thick smear method（one sample for three tests）, and results were analyzed by SPSS 22.0 software.A total of 13 660 persons were examined, and 140 were infected with roundworms (infection rate 1.05%), comprising of 133（95.00%） light infections and 4（5.00%） moderate infections.No heavy infection was found.The prevalence of Ascaris was higher in Ping′an （2.49%） and Minhe（2.13%） than in other counties （χ² = 70.924, P < 0.05）.The population of 0-10 years showed higher infection rate than other age groups（P < 0.05）.The Han population showed higher infection rate than other ethnicities（P < 0.05）.The preschool children had higher infection rate than other occupation groups （P < 0.05）.Unfertilized Ascaris eggs accounted for 99.29% (139/140), and only one case was found with fertilized eggs in Gonghe county.The results indicate that both prevalence and intensity of Ascaris infection are low in Qinghai.
