摘　　要：为了解黑龙江省人群华支睾吸虫感染现状。于2015年4—6月,按照《全国人体重点寄生虫病调查方案》要求,采用分层整群随机抽样的方法在全省范围内抽取104个农村地区和15个城镇地区调查点,将农村地区划分为长白山-千山山地、东北平原东部、三江平原、小兴安岭山地针阔混交林等4个生态区,每个调查点调查人数不少于250人。采用改良加藤厚涂片法(一粪二检)检测被调查者粪样,镜检华支睾吸虫虫卵并计数。结果显示,共调查30280人,感染者747例,感染率为2.47%。农村地区、城镇地区人群感染率分别为2.77%(734/26456)和0.34%(13/3824),地区间差异有统计学意义(χ^(2)=82.295,P<0.05)。感染者以轻度感染为主(82.33%,615/747),男、女性感染率分别为3.05%(462/15171)和1.89%(285/15109),性别间差异有统计学意义(χ^(2)=42.261,P<0.05);30~39岁年龄组感染率最高(3.32%,147/4430),年龄组间差异有统计学意义(χ^(2)=122.182,P<0.05);农(牧、渔)民感染率最高(3.16%,692/21914),职业间差异有统计学意义(χ^(2)=164.846,P<0.05);初中文化程度组感染率最高(3.46%,499/14425),文化程度间差异有统计学意义(χ^(2)=124.596,P<0.05);汉族人群感染率最高(2.51%,739/29487),各民族人群间差异有统计学意义(χ^(2)=8.395,P<0.05)。农村地区感染者以轻度感染为主(82.56%,606/734),男、女性感染率分别为3.39%(454/13378)、2.14%(280/13078),性别间差异有统计学意义(χ^(2)=38.468,P<0.05);30~39岁年龄组感染率最高(3.78%,145/3841),年龄组间差异有统计学意义(χ^(2)=111.315,P<0.05);干部、企事业职员感染率最高(5.05%,10/198),职业间差异有统计学意义(χ^(2)=103.863,P<0.05);初中文化程度组感染率最高(3.88%,496/12792),文化程度间差异有统计学意义(χ^(2)=127.308,P<0.05);汉族人群感染率最高(2.82%,726/25734),各民族人群间差异有统计学意义(χ^(2)=8.903,P<0.05);三江平原生态区感染率最高(8.75%,575/6574),生态区To understand the current status of Clonorchis sinensis infection in the population of Heilongjiang Province,the survey sites were selected from 104 rural areas and 15 urban areas in the Province in April—June2015,using stratified cluster random sampling method,in accordance to the guideline of the National Survey,Program for Key Human Parasitic Diseases.The rural areas were divided into four ecoregions:Changbai MountainQianshan Mountains,the Eastern Northeast Plain,Sanjiang Plain,and Xiaoxing’an Mountain coniferous and broadleaved mixed forest.The number of people surveyed at each survey site was no less than 250.The modified Kato thick smear method was used to examine the participants’fecal samples(two slide-reading/sample)for C.sinensis eggs and counted.Of the 30280 examinees,747 were found infected,with an infection rate of 2.47%.The infection rate in rural and urban areas was 2.77%(734/26456)and 0.34%(13/3824)respectively,with the difference being statistically significant(χ^(2)=82.295,P<0.05).Most of the infected showed mild infection(82.33%,615/747).The infection rate was 3.05%(462/15171)in males and 1.89%(285/15109)in females,showing significant difference between the sexes(χ^(2)=42.261,P<0.05).The highest infection rate was seen in the age group of 30-39 years(3.32%,147/4430),revealing significant difference between the age groups(χ^(2)=122.182,P<0.05).The highest infection rate was found in farmers(animal husbandry and fishery)(3.16%,692/21914),with the difference between occupation groups being statistically significant(χ^(2)=164.846,P<0.05).The infection rate differed significantly among the participants with different levels of education(χ^(2)=124.596,P<0.05)and was highest in the group with junior high school education(3.46%,499/14425).The rate was significantly different between different ethnic groups(χ^(2)=8.395,P<0.05),with the Han group having the highest infection rate(2.51%,739/29487).In rural areas,most of the infected people showed mild infection intensity(82.56%,606/734).The in
