Objective To investigate the epidemiological trend of human intestinal helminth infections in Yancheng City， Jiangsu Province from 2006 to 2015， so as to provide the evidence for formulating further control strategies. Methods The surveillance data of human intestinal helminth infections were collected and analyzed in Yancheng City from 2006 to 2015. Results From 2006 to 2015， 110 746 person?times of residents in Yancheng City were surveyed in Yancheng City， and 1 732 samples were positive of human intestinal helminth infections. The infection rate of human intestinal helminthes was highest in 2006 ［4.59% （410/8 941）］， and lowest in 2013 ［0.19% （23/12 165）］. The infection rate of human intestinal helminthes was significantly decreased over time （χ2]= 27.78， P < 0.001）. The human infection rates of Ascaris lumbricoides， hook worm and Trichuris trichura were all decreased over time （Z = -27.75， -22.23 and -16.17， all P < 0.001） from 2006 to 2015， with the reduction rates of 96.57%， 92.31% and 96.47%， respectively. The average EPG of A. lumbricoides， hook worm and T. trichura were 2 534， 360 and 154 respectively， and 1 694 （97.81%） cases were light infections. Totally 1 174 cases of Enterobius vermicularis were found in children under 12 years old， and the cases were decreased over time （χ2]= 12.46， P < 0.001）. Conclusions The infection rate of human intestinal helminthes in Yancheng City decreases over time from 2006 to 2015， and the control work is effective.
