Objective To understand the situation and epidemiological characteristics of Soil-transmitted nematodes infections in Tonghua City from 2017 to 2020,and to provide a scientific basis for formulating prevention and control strategies and evaluating prevention and control effects.Methods From 2017 to 2020,five communities(villages)in Tonghua City were selected by district,and 200 permanent residents over 3 years of age were selected in each community(village)each year to collect fecal samples from the surveyed population and detect Soil-transmitted nematode eggs used the modified Kato smear method.Results From 2017 to 2020,a total of 4 000 people were investigated in Tonghua City,and 81 people were detected to be infected with Soil-transmitted nematodes(the infection rate of 2.02％),all of which were infected with roundworm.The Soil-transmitted nematodes infections differed among different years,regions,genders and occupations,and the differences were statistically significant(year:x2=40.260,P＜0.05;region:x2=38.483,P＜0.05;gender:x2=10.220,P＜0.05;occupation:x2=22.405,P＜0.05).The Soil-transmitted nematodes infections were basically the same among people of different ages and literacy levels,and the differences were not statistically significant(age:x2=8.517,P＞0.05;literacy level:x2=6.203,P＞0.05).Conclusion The Soil-transmitted nematode infections in Tonghua City are mainly Roundworm from 2017 to 2020,with an overall decreasing trend in the infection rate.In view of the actual situation in Tonghua City,we should continue to take targeted intervention measures to further promote the prevention and control of Soil-transmitted nematode infections and reduce the infection rate of Soil-transmitted nematodes.
