摘　　要：目的了解广西东部4县(市)土源性线虫和华支睾吸虫人群的感染状况及流行特征,为制定防控措施和评价防控效果提供依据。方法按生态区和经济水平等,每个县随机选取2~5个乡镇的某个村屯为调查点,调查对象为1岁以上常住居民,采用改良加藤厚涂片法(Kato-Katz法)检测土源性线虫、华支睾吸虫等蠕虫虫卵,计算感染率和感染度,分析流行特征。结果共调查了3 280人,土源性线虫感染27例,感染率为0.82%,除2例为中度感染外,其余均为轻度感染。华支睾吸虫感染451例,感染率为13.75%,轻度感染占了81.37%;不同县(市)感染率差异有统计学意义(χ^(2)=738.88,P<0.01),藤县高达37.90%;男性感染率(18.72%)高于女性(9.15%)(χ^(2)=63.14,P<0.01),不同年龄组感染率差异有统计学意义(χ^(2)=148.90,P<0.01),最高为30岁~组(22.24%);不同职业人群感染率差异有统计学意义(χ^(2)=116.45,P<0.01),教师达到18.92%;不同教育程度人群感染率差异有统计学意义(χ^(2)=84.85,P<0.05),初中人群感染率最高(18.98%)。结论广西东部4县(市)土源性线虫人群感染率已处于散发水平,不宜采取群体性化疗驱虫,提倡采取自愿检查、病例驱虫的措施;人群华支睾吸虫感染率较高,已成为了当地重要的公共卫生问题之一,政府需要给予足够重视,加大综合防控的力度。Objective To understand the infection status and epidemic characteristics of soil-transmitted nematodes and Clonorchis sinensis in four counties of eastern Guangxi, and to provide basis for formulating control measures and evaluating the control effect.Methods According to the ecological zone and economic level, a certain village from 2 to 5 townships from each county was randomly selected as the survey point. The survey objects were residents over 1-year-old. Kato Katz method was used to detect the eggs of soiltransmitted nematodes, Clonorchis sinensis, and others helminths. The infection rate and degree of infection were calculated, and the epidemic characteristics were analyzed.Results A total of 3 280 people were investigated, 27 of them were infected with soil-transmitted nematodes, the infection rate was 0.82%. Except 2 cases of moderate infection, the rest were mild infection. There were 451 cases of Clonorchis sinensis infection, the infection rate was 13.75%, the mild infection was accounted for 81.37%. There was statistical significance in infection rate among different counties(χ^(2)=738.88, P<0.01), the infection rate of Tengxian was as high as 37.90%. The infection rate of males(18.72%) was higher than females(9.15%)(χ^(2)=63.14, P<0.01). The infection rate between different age groups was statistically significant(χ^(2)=148.90, P<0.01), and the highest infection rate was 22.24% in the 30-year-old group. The difference of infection rate among different occupational groups was statistically significant(χ^(2)=116.45, P<0.01), in which the teacher group reached 18.92%. The difference of infection rate among different educatioal groups was statistically signifcant(χ^(2)=84.85, P<0.05), in which the junior high school was the highest(18.98%).Conclusion The infection rate of soil-transmitted nematodes in the four counties in eastern Guangxi is at a sporadic level, and it is not suitable to take mass deworming chemotherapy. It is recommended to take the measures of self-examination and case deworming.
