河南省许昌市2012年土源性线虫感染调查报告

Investigation of Soil-Transmitted Nematode Infections in Xuchang City of Henan Province in 2012

2012按照《全国土源性线虫病监测方案（2011修订版）》要求抽取河南省许昌市魏都区、鄢陵县和禹州市作为土源性线虫调查点。采用改良加藤厚涂片法（一粪三检）对调查点3周岁以上居民进行土源性线虫检测。同时，对3～12周岁儿童采用透明胶纸肛拭法检测蛲虫卵，373份肛拭样品中检出阳性1份，阳性率为O．3％。共检测2991份粪样，土源性线虫总感染率为4．3％（128／2991）。与2004年河南省土源性线虫感染率（9．5％）相比，下降了55．1％，与2010年的11．6％相比下降了63．0％。蛔虫、鞭虫、钩虫和蛲虫感染率分别为3．7％（110／2991）、0．3％（9／2991）、0．1％（3／2991）和0．2％（6／2991），均为轻度感染。农民土源性线虫感染率（5．5％，113／2059）最高，散居儿童（3．1％，3／98）次之。

The Weidu District, Yanling County and Yuzhou City were selected in Xuchang City for investigation of the status of soil-transmitted nematode infections in 2012, in accordance with the National Monitoring Program for Soil-Transmitted Nematodiasis （2011 Revised Edition）. Kato-Katz technique was used to detect soil- transmitted nematodes in feces of residents over 3 years old, and the cellophane tape peri-anal swab method was used to detect pinworm eggs in children between 3-12 years. A total of 2 991 fecal samples were examined. The total infection rate of soil-transmitted nematodiasis was 4.3%（128/2 991）, decreased by 63.0% and 55.1% when compared with that in 2010 （11.6%） and that in Henan Province in 2004 （9.5%） respectively. The infection rates of roundworms, whipworms, hookworms and pinworms were 3.7% （ 110/2 991 ）, 0.3% （9/2 991 ） , 0.1% （3/2 991 ） , and 0.2% （ 6/2 991） , respectively, all showing mild intensity of infection. The infection rate of soil-transmitted nematodiasis was highest in farmers （5.5%, 113/2059）, followed by children （3.1%, 3/98）.
