2005年至2010年某市血吸虫病国家监测点监测结果分析

Analysis of National Surveillance of Schistosomiasis in a City during 2005-2010

目的为了系统、准确、及时了解血吸虫病流行现状,掌握扬中市血吸虫病疫情动态和影响因素,为今后的防治工作提供科学依据。方法按《全国血吸虫病监测方案》的方法,2005年至2010年对国家血吸虫病监测点石城村开展螺情、病情等纵向观察并进行统计分析。结果 2005年钉螺面积、活螺框出现率、活螺平均密度、钉螺感染率、血检阳性率分别为16.43hm2、42.17%、1.27只/0.1m2、0只/0.1m2、1.81%,2010年钉螺面积、活螺框出现率、活螺平均密度、钉螺感染率、血检阳性率分别为16.43hm2、3.92%、0.02只/0.1m2、0只/0.1m2、0.51%。2010年与2005年相比,活螺框出现率、活螺平均密度、居民血检阳性率分别下降了90.70%、98.43%、71.82%。结论 2005年至2010年扬中市血吸虫病国家监测点血吸虫病疫情得到控制,但钉螺依然存在,江滩综合治理、传染源监测等工作仍需进一步加强。

Objective To understand the epidemic situation of schistosomiasis and influential factors based on national surveillance in Yangzhong city, so as to provide scientific evidences for making out prevention and control measures. Methods According to the national surveillance scheme on schistosomiasis, from 2005 to 2010, a longitudinal survey of schistosomiasis was carried out in Shicheng village, Yangzhong city, Jiangsu province, a national schistosomiasis surveillance site. Results The area with snails, the occurrence rate of frames with living snails, the average density of living snails, the snail infection and the positive rate of serum in residents were 16.43hm2, 42.17%, 1.27No./0. l m2, 0No./0. l m2, 1.81% in 2005. The area with snails, the occurrence rate of frames with living snails, the average density of living snails, the snail infection and the positive rate of serum in residents were 16.43hm2, 3.92%, 0.02No./0. lm2, 0No./0.1m2, 0.51% in 2010. The occurrence rate of frames with living snails, the average density of living snails, and the positive rate of serum in residents in 2010 declined 90.70%, 98.43% and 71.82%, respectively compared with those in 2005. Conclusions The endemic situation of schistosomiasis in the national surveillance sites in Yangzhong is eontroled from 2005 to 2010, but snails still exist,the comprehensive control in marshland and surveillance of infectious sources should be strengthened.
