2006年江苏省国家级血吸虫病监测点疫情监测

目的 掌握江苏省血吸虫病疫情动态，为制订防治策略和考核防治效果提供依据。方法按《全国血吸虫病监测方案》的方法，在全省8个国家级监测点开展血吸虫病疫情监测。结果3个监测点发现了粪检阳性者，常住居民总感染率为0．15％，流动人口感染率为2．74％。7个监测点查到钉螺，其中4个监测点查到感染性钉螺。1个监测点发现粪检阳性家畜，其中牛和羊的总感染率分别为2．82％和3．19％。结论监测区疫情较2005年有所下降，但流动人群和局部区域的家畜感染率仍较高，需进一步加大防治力度，以更有效地降低当地的血吸虫病流行水平。

Surveillance on endemic situation of schistosomiasis in national surveillance sites of Jiangsu Province, 2006

Objective To understand the dynamic endemic situation of schistosomiasis in order to get the evidence for policy-making and evaluation of schistosomiasis control in Jiangsu Province. Methods According to The National Scheme of Schistosomiasis Surveillance, the endemic situation of schistosomiasis was monitored in 8 national schistosomiasis surveillance sites of Jiangsu Province. Results There were 3 sites where schistosomiasis patients were found （stool examinations were positive）, the infection rates were 0. 15% in the permanent residents and 2. 74% in the mobile population. There were 7 sites where Oncomelania snails were found and 4 sites where the infected snails were found. There was 1 site where schistosomiasis livestock was found （stool examinations were positive）, and the infection rates were 2. 82% and 3.19% in the cattle and sheep, respectively. Conclusions Compared with 2005, the prevalence in the surveillance sites decreases in 2006. However, the infection rates of Schistosoma japonicum are still high in the mobile population and livestock in some sites. Therefore, the control measures should be strengthened to further reduce the prevalence of schistosomiasis.
