RÉSUMÉ
Objective To understand the infection status of soil-transmitted nematodes in Xinchang County,so as to offer the evidence for the formulation of control measures.Methods The infection of soil-transmitted nematodes in residents was in-vestigated by using the Kato-Katz method and cellophane anal swab.Results A total of 3 069 people were examined in 2009,2012 and 2017,of which 1 520 people were male and 61 people were infected,with the infection rate of 4.01％;1 549 were women and 54 people were infected,with the infection rate of 3.48％.The infection rates of soil-transmitted nematodes in 2009,2012 and 2017 were 4.60％,4.29％and 2.35％,respectively,and the total infection rates were decreased(Χ2= 7.151,P＜0.05).Conclusion The rate of soil-transmitted nematode infection in Xinchang County is declining,and it is at a low epidemic level.
