Abstract: 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 investigated 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.
