2006年浙江省血吸虫病疫情监测结果分析

Analysis of endemic situation in national schistosomiasis surveillance sites in Zhejiang Province in 2006

目的掌握2006年浙江国家级血吸虫病监测点疫情状况。方法根据《全国血吸虫病监测方案》,在常山县开展血吸虫病监测。结果2006年白石镇小白石村监测点未查出当地新感染的病人与家畜,但在常山县查出1例输入性急性病例。监测点查出有螺面积2260m2,活螺平均密度0.10只/0.11m2,未查到感染性钉螺。结论监测点存在残存钉螺,常山县查出输入性传染源,当地潜在血吸虫病重新流行的可能,必需加强当地螺情和输入性传染源的监测工作。

Objective To understand the endemic situation in national schistosomiasis surveillance sites in Zhejiang Province in 2006. Methods According to the scheme of the national schistosomiasis surveillance, the surveillance work of schistosomiasis was continuously carried out based on the work in 2005. Results There were no local schistosomiasis cases, but an import acute case was found in the surveillance site. The residual snail area was 2 260m^2. The average density of riving snails was 0.099 1/0.11m^2, and no infected snail was found. Conclusion There are some residual snails and import schistosomiasis cases in the surveillance site, which may lead to the revival of schistosomiasis endemic. The surveillance on residual snails and import schistosomiasis should be reinforced.
