| 目的了解深圳市居民华支睾吸虫感染状况、传播途径和流行特征。方法用血清免疫学筛查, 采用酶联免疫吸附试验(ELISA)方法, 对检出的阳性者进行粪便病原学检查;同时进行问卷调查与华支睾吸虫感染相关的生活和行为方式;现场调查华支睾吸虫病传播途径。结果共调查1473名6～65岁深圳市居民, 男性710名, 女性763名;有70名华支睾吸虫阳性(4.75%);男性的感染率为4.22%(30/710), 女性感染率为5.24%(40/763), 男女性间比较无差异;但每克粪便中的虫卵数男性高于女性, 表明男性的感染强度高于女性;人群中不同年龄组表现了不同的感染率, 最高感染率的年龄组主要分布在31～50岁, 高于30岁以下和50岁以上年龄组;54% 的被调查者不了解华支睾吸虫及其传播途径, 27%的被调查者每月吃1～2次淡水生鱼片, 5%的家庭使用同样的刀具处理淡水鱼和蔬菜, 40%的养鱼者利用动物和人的粪便喂食鱼类。结论深圳市楼村是华支睾吸虫病流行村, 居民传统嗜好生吃淡水鱼和生态养殖的生产方式是造成华支睾吸虫病流行的主要因素。 |

| Objective To study the transmission route and epidemiologicaI features of Clonorchis sinensis infection in shenzhen area-the biggest immigration city of southern China.Methods In this study.we examined 1473 individuals(710 males and 763 females)to determine the current status of C.sinensis infection among the people in one village in Zhujiang river region, Guangdong province, China.Blood samples were detected on antibody of C.Sinensis with enzyme linked immunosorbent assay, and stool specimens from sera positive cases were examined by modified Kato-Katz thick smear to confirm the density of infection. People were interviewed on their life styles under the structured questionnaire which was administered by trained staff members.Major content of the questionnaire included eating raw fish, using the same utensils for both raw fish and cooked food, using feces of domestic animals and human feces to feed fish and So on.Results Among 1473 people examined, 70(4.75%)were found infected with C.sinensis.By counting eggs per gram feces(EPG), it was found that heavy intensities of infection in males was stronger than that of females, and the overall average EPG was 41.87.of 1473 interviewees, 54%of them did not know about nuke disease or its transmission route, 12% of those who knew about the fluke but believed that the infection caused no ham or only slight harm to their health.27%of the interviewees ate raw fish at least l-2 times per months with 5%of the families using the same utensils for both raw fish and cooked food.40%of the fish ponds owners fed their fish with the feces of domestic animals and human feces. Conclusion Together with these results, unhealthy behaviors, poor knowledge, inappropriate Farming/fishery practices, eating raw fish were important factors influencing the C.sinensis, prevalence in humans. |
