四川省基本消灭丝虫病后的巩固和监测措施(1982～1996年)

CONSOLIDATING MEASURES AND SURVEILLANCE ACTIVITIES IN SICHUAN DURING THE PERIOD OF 1982-1996 AFTER FILARIASIS BASICALLY ELIMINATED

四川省于1979～1983年在秀山县试点取得一个县净化丝虫病的成功经验，并于1982年开始逐步在全省丝虫病流行区推广。30个流行县（市、区）在基本消灭丝虫病后三年内实施巩固措施，经过11—14年病原学、媒介和血清学监测已连续8～14年来检出微丝蚴血症者，9～14年未发现感染人体幼丝虫的蚊媒，纵向监测点人群抗体阳性率接近非流行区人群抗体水平，达到卫生部颁布的消灭丝虫病标准，证实基本消灭丝虫病后的巩固和监测措施适合四川省实际情况。分析认为基本消灭丝虫病后实施巩固措施和进行足够范围的人群横向监测和重点人群监测可较迅速彻底地检出和消除残存传染源，尽快达到消灭丝虫病的标准。

Successful experience on measures for controlling filariasis comprehensively has been achieved in demon-stration area of Xiushan County,Sichuan Province during 1979 - 1983,and expanded to endemic areas step by step since 1982. In all of the 30 endemic counties (cities,districts),measures for consolidating the control ef-fect were carried out within 3 years after filariasis being basically eliminated. Since then,no microfilariemia cases were detected out in succesive 8- 14 years,and no microfilaria infected mosquito vectors found in succe-sive 9 - 14 years through 11 - 14 year's aetiological,vector and serodiagnostic surveillance activities. Besides,the human antibody positive rate in longitudinal surveillance areas approached the antibody level in non-en-demic areas. All these indices have reached the criteria of filariasis eradication issued by the Ministry of PublicHealth,China. The practise has been confirmed that the measures and activities for consolidating and surveil-lance on filariasis were practical in Sichuan. The authors suggested that in order to detect out and then to e-liminate the residual infection sources rapidly and completely,it was necessary to carry out consolidating mea-sures,cross-sectional surveillance in both fair-sized person and area,and surveillance on key communities afterthe filariasis being basically eliminated.
