2005-2010年扬中市国家级血吸虫病监测点疫情监测

Surveillance of schistosomiasis in a national surveillance site of Yangzhong City, 2005-2010

2005-2010年对扬中市国家血吸虫病监测点石城村疫情监测显示,6年钉螺面积均为16.43hm2,活螺框出现率和活螺平均密度均呈逐年下降趋势,仅2007年发现感染性钉螺。血检阳性率分别为1.81%、0.98%、0.29%、0.28%、0.47%和0.51%;粪检均未发现阳性,居民感染率0。连续6年未发生急性血吸虫感染病例,未查出晚期血吸虫病人和血吸虫感染病畜。结果提示,扬中市国家级监测点血吸虫病疫情得到有效控制;但钉螺依然存在,需进一步加强江滩综合治理和传染源监测。

The surveillance of schistosomiasis in Shicheng Village, a national schistosomiasis surveillance site in Yangzhong City from 2005 to 2010 showed that snail areas were 16.43 hm^2, the occurrence rates of frames with living snails and mean densities of living snails exhibited a declining trend year by year, and the infected snails were only found in 2007. The sero-positive rates in residents were 1.81%, 0.98%, 0.29%, 0.28%, 0.47% and 0.51%, respectively from 2005 to 2010. However, no stool-examination-positive persons were detected. During the period, no acute infections occurred, and no advanced cases and infected animals were detected. It is indicated that schistosomiasis has been effectively controlled in the surveillance site. However, snails remain present, so comprehensive control and surveillance of infectious sources should be further strengthened.
