To understand the endemic situation of soil-transmitted nematodiasis (Ascaris lumbricoides, Trichuris trichiura and Ancylostoma sp.) in Huaiyang County, Henan Province. Over 1 000 fecal samples from inhabitants in Huaiyang County of Henan Province were collected each year during 2011-2015, in which the soil-transmitted nematodes eggs and other intestinal helminth eggs were examined by Kato-Katz technique. The helminth-positive samples were examined by filter paper culture method to identify the species of hookworm. The cellophane swab method was used to detect Enterobius vermicularis eggs in children aged 3～12 years. Soil samples were collected from vegetable field, lavatory, courtyard and kitchen of 10 families randomly selected in each year to examine Ascaris eggs by a modified saturated sodium nitrate floatation method. In 2011-2015, 5 229 people were examined and 54 person infected with intestinal helminths were found. Five intestinal helminthes, A. lumbricoides, T. trichiura, Ancylostoma duodenale, Enterobius vermicularis and Trichostrongylus orientalis were found with 13, 2, 9, 29 and 1 infection person respectively. All showed mild infection and no multiple infections were found. There was no significant difference between the year 2015 which had the highest soil-transmitted nematode infection rate 0.6%（7/1 134） and the year 2013 which had the lowest infection rate 0.3%（3/1 037）（P>0.05）. The infection rate of intestinal helminths was highest in group of <10 years（2.8%, 25/905）, followed by the groups of >70 years（1.6%, 4/256） and 30～40 years（1.2%, 8/671）（P>0.05）. The average infection rate of E. vermicularis was 1.8%（18/993） The infection rate of E. vermicularis was relatively higher in kindergarten kids（1.6%, 6/366） and students（1.3%, 13/1 005） than that in farmers（0.3%, 10/3 782）（P<0.01）. No Ascaris eggs were found in the 200 randomly collected soil samples. The intestinal helminth infection status maintaines at low level in Henan Province during 2011-2015.
