2000-2002年江苏省血吸虫病监测点疫情分析

目的 掌握江苏省血吸虫病疫情监测点建立3年来的疫情变化态势。方法 建立12个疫情监测点，按《全国血吸虫病疫情监测点方案》规定的方法，每年开展螺情及病情等纵向监测。结果 全省大部分监测区螺情回升，江滩地区感染性钉螺快速增长；耕牛感染率下降，传染源趋于多样化；居民感染率较低且相对稳定，但存在发生重大疫情的可能。结论 现有控制措施的力度虽能减缓疫情的发展速度，但难以阻断疫情的发展趋势。必须更深入地研究新的疫情特点和发展规律，探索适应当前社会、经济及自然环境特点的更有效的防治对策。

Objective To identify the trend of endemic situation among surveillance sites in Jiagsu Province from 2000 to 2002. Methods Twelve schistosomiasis surveillance sites were es-tablished ,and the longitudinal, surveillance was carried out. Results The related index of snail increased in most of surveillance sites, the rates of positive snails rose rapidly in marshlands. The infection rates of Schitosoma janponicum of cattle decreased and infection rates of human were relatively steady. However, there was still the danger of heavy endemic. Conclusion Current control strategies can not effectively adapt to the endemic situation of schistosomiasis, although which have some effects on control of morbidity.
