摘要
目的了解重庆市华支睾吸虫病流行趋势,为制定防治方案提供依据。方法采集监测村5岁以上的常住人群粪便标本300份,采用水洗沉淀+醛醚法检查标本中的华支睾吸虫卵。感染因素调查,华支睾吸虫感染者与未感染者按1∶4匹配调查。采集调查村常见鱼种,每条鱼取其鳍、腮、尾等部位肌肉压片镜检囊蚴。健康教育前后问卷调查,了解健康教育效果。结果共调查367人,检出华支睾吸虫卵感染者12人,感染率为3.27%;性别间感染率差异无统计学意义(P>0.05),感染者均为农民,年龄最小32岁,最大73岁。感染组12人,对照组48人,对吃生鱼半生鱼、吃火烧鱼、用人畜粪便喂鱼等因素分析发现,各因素感染组和对照组差异无统计学意义。共检测4种淡水鱼131尾,检出华支睾吸虫囊蚴12尾,阳性率为9.16%。其中仅麦穗鱼和半餐(白参)检出华支睾吸虫囊蚴,麦穗鱼囊蚴检出率高达25.00%,显著高于半餐(P<0.05)。健康教育前学生和村民分别调查69人和50人,知晓率分别为26.09%和44.61%,健康教育后学生和村民调查69人和58人,知晓率分别为84.06%和98.28%,健康教育后两类人群知晓率均有统计学意义(P<0.01)。结论我市华支睾吸虫病经过多年的大力防治,取得了显著成绩,但流行区范围并没有缩小,人群感染率仍较高,仍需继续开展防治和监测工作。
Objective To analyze the epidemiology of clonorchiasis sinensis and provide basis for the prevention and control programs. Method 300 stool specimens of the population of age over 5 years were collected in the village. The eggs of Clonorchis sinen.sis were examined by method of sedimentation and formalin-ether sedimentation technique. The infected and control people were matched according the proportion of 1：4. The common local fish were collected in the village. The muscle was obtained from the fin, cheek, tail of the collected fish, The metacercaria was examined in the muscle by the microscope. The effect of health education was investigated, Result 12 of 367 people were infected, with an infection rate of 3.27%. There was no significant difference of the infection rate between male and female （P〉 0.05）. The infected individuals were all farmer, The youngest was 32 and the oldest was 73 years old, There were 12 persons in the infected group and 48 persons in the control group. There was no significant difference of the infection rate between the people eating raw fish, half cooked fish, BBQ fish, or fish fed with faeces. 12 Clonorchis sinensis metacercariae were found in 131 fish of 4 kinds of fresh water fish and the metacercariae rate was 9.16%. The metacercariae was found in the Pseudorasbora parva and Hemiculter leucisulus. The metacercariae rate of Pseudorasbora parva （25.00%） was higher than Hemiculter leucisulus （P〈0.05）. The rate of knowledge about clonorchiasis sinensis of students was 26.09% and that of villagers was 44,61% before attending health education, The rate of knowledge about clonorchiasis sinensis of students was 84,06% and that of villagers was 98.28% after attending health education. There was significant difference between the two groups in the rate of knowledge about the disease before and after attending health education （P〈0.01）. Conclusion After many years of controlling clonorchiasis sinensis, the infection rate was low. But the area having Clonorchis sinensis is not reduced and the rate of infection still needs to be reduced. The prevention and control program of the disease have to be continued.
