目的 了解亚洲无钩绦虫病流行因素及流行环节,掌握流行特征,探索综合防治方法。 方法 选择带绦虫病流行区兰坪县河西乡箐花村和三界村为防治试点,开展亚洲无钩绦虫流行病学调查。采用药物驱虫及健康教育(箐花村)等措施控制亚洲无钩绦虫病。 结果 病史访问 2 214 人, 查到近期排亚洲无钩绦虫节片者 886 人,感染率分别为箐花村42.12%(489/1161),三界 37. 70% ( 397/1053 )。未发现有癫痫病史者和皮下结节者。人群感染率,男性38.55%,女性 41. 44%,差异无显著性;最小感染年龄为 9 个月,最大 90 岁; 30 ~ 50 岁组感染率最高,在 55. 99% ~60.66%之间;普米族居民感染率为46.69%,高于其他民族;农民感染率为 51.77%,高于其他职业人群。饮食习惯调查,生食猪肝者占调查人数的95.12%,感染率为41.55%,显著高于不生食猪肝者(6.48%)。不同牲畜饲养户亚洲无钩绦虫感染率差异有显著性(χ2=299.266,P<0.01)。3年累计复查7 771人次,驱虫3 285人次,药物驱虫治愈率分别为驱绦胶囊82.50%(509/617),吡喹酮75.00%(150/200)。采取综合性防治措施后,箐花村居民生食猪肝者所占比例从防治前的95.95%下降至36.32%,厕所普及率从 1.48%上升至 39.41%,亚洲无钩绦虫人群感染率从 42.12%下降至17.67%。三界村防治后上述指标无显著变
Objective To understand the prevalence and prevalence of leptothecia in Asia, master the epidemiological features and explore integrated prevention and treatment methods. Methods Epidemiological investigation of tapeworm in Asia was conducted for the prevention and control of Pseudobagrus umbellatus in Hexi Township, Lanping County, Lanping County. The use of drug deworming and health education (Huang Hua Village) and other measures to control the Asian hookworm disease. Results A total of 2 214 medical records were interviewed. Among them, 886 were found in the recent Asian lineage-free tapeworm. The infection rates were 42.12% (489/1161) and 37.70% (397/1053) respectively in Yinghua Village. No history of epilepsy and no subcutaneous nodules found. The infection rate of the population was 38.55% for males and 41.44% for females, with no significant difference. The minimum age of infection was 9 months and the maximum was 90 years old. The infection rate was the highest among 30 ~ 50 years old group, ranging from 55. 99% to 60.66% . The infection rate of Pumi residents was 46.69%, higher than that of other ethnic groups. The infection rate of farmers was 51.77%, higher than other occupational groups. Dietary habits survey, raw pig liver accounted for 95.12% of the survey population, the infection rate was 41.55%, significantly higher than non-eating pig liver (6.48%). There was a significant difference in the prevalence of Hookworm in Asia among different livestock keepers (χ2 = 299.266, P <0.01). In the past three years, a total of 7,771 person-reviews and 3,285 person-repellent insecticides were reexamined. The cure rates of the drug repellent were 82.50% (509/617) and 75.00% (150/200) of praziquantel respectively. After adopting comprehensive prevention and control measures, the proportion of live pigs in Huanghua Village decreased from 95.95% before prevention to 36.32%, and the prevalence of latrines increased from 1.48% to 39.41%. The infection rate of the non-hookworm in Asia declined from 42.12% To 17.67%. After the prevention and treatment of Sanjiecun no significant change in the above indicators
