【摘要】 监测指标理论研究:阐明残存螺点螺口消长3年形成不同螺口的螺点全频率分布;ELISA及COPT检测控制流行地区儿童血吸虫抗体消退后的试验反应值全频率分布;水体内低密度毛蚴对钉螺形成低感染率和低密度尾蚴对小鼠形成高感染率的传播关系。上述结果为评价残存传播条件的流行病学意义,及常用于监测工作的检测技术的灵敏度和制定监测方案提供科学依据。监测方案及技术措施研究:观察不同监测方案试点和技术措施的效果,为制定监测方案提供现场实践依据。拟定基本消灭地区清查方案,消灭地区监测方案、重新传播流行预测方案和血防巩固监测指标。更多还原

【Abstract】 Studies on theory of monitoring standard expound: the distribution of whole frequency in different snail sites which were formed from remnant snails through three years growing and death; the kinetics of antibody level of children in schi-stosomiasis controlled and basically controlled areas; the distribution of whole frequency of ELISA and COPT values which had dropped to the level of children in non-epidemic areas; the relationship between low density miracidia with low infection rate of remnant snails; and the relationship between low density circaria with high infection rate of exposed mice. The results may provide scientific data for evaluating the significance of conditions for remnant transmission in epidemiology and making monitoring plans. Studies on monitoring scheme and measures expound:the observation of different monitoring schemes and efficacy of techniques and measures for monitoring may provide scientific data for monitoring schemes in field implementation. The schemes for search of snails and patients in basically controlled and controlled areas, the prospective examination of re-transmission and the monitoring standard in controlled areas were proposed in this article.更多还原
