为了解基本消灭丝虫病后在尚有残存传染源和传播媒介存在情况下的流行规律及传播趋势,我们建立了监测站,从1984～1991年连续8年对原丝虫病流行区进行了监测。一、内容和方法 1.传染源监测在基本消灭丝虫病后未再采取防治措施的原不同流行区的郯城、苍山、峰城、嘉祥、宁阳等8个县区25个固定监测点,按不同感染度以村为单位,每年对周岁以上居民血检1次。对微丝蚴阳性者每年7～9月每月1次定时、定量(120μl)血检。凡经2年血检6次以上均阴性者为转阴。另外对1～10岁儿童和流动人口每年重点调查。 2.丝虫病体征调查在基本消灭丝虫病10年以上监测点的县、乡、村调查丝虫病主要临床症状、体征(象皮腿、鞘膜积液、乳糜尿)。
In order to understand the prevailing laws and dissemination trends in the presence of residual sources of infection and transmission media after the basic elimination of filariasis, we established a monitoring station to carry out the endemic filariasis epidemic area for eight consecutive years from 1984 to 1991 monitor. I. Contents and Methods 1. Monitoring of Infectious Sources 25 fixed monitoring points in eight counties and districts, including Yuncheng, Cangshan, Fengcheng, Jiaxiang and Ningyang, in the original epidemic-prone areas that did not take preventive measures after the basic elimination of filariasis, According to the different degree of infection to the village as a unit, each of the residents over the age of a blood test 1. Microfilaria positive for 7 to 9 months a month every month time, quantitative (120μl) blood tests. Where by 2 years of blood tests more than 6 times were negative for the negative. In addition to 1 to 10-year-old children and migrants focus on annual surveys. 2. Filariasis signs investigation The main clinical symptoms and signs of filariasis (such as skin legs, hydrocele, chyluria) were investigated in counties, townships and villages that basically eliminated filariasis at monitoring points over 10 years.
