摘    要:目的 了解江苏省钉螺和感染性钉螺分布情况,为制定防治规划提供科学依据。方法根据全国和江苏省血吸虫病疫情监测方案的要求,在全省血吸虫病流行区选择有代表性的82个流行村作为监测点,开展钉螺和感染性钉螺分布情况的监测调查。结果 全省监测村中有42个测村发现了钉螺,占监测村的51. 22%;有10个监测村发现了感染性钉螺,占监测村的12. 20%。监测村发现的钉螺面积占调查总面积的27. 86%,发现的感染性钉螺面积占总有螺面积的17. 35%。监测村总的钉螺密度为0.16只10.1nl2,总的感染性钉螺平均密度为0.000 44只10.1 mz。结论全省螺情仍不容乐观,有可能成为2010年实现江苏省达到“血吸虫病传播控制”目标的主要制约因素。全省在今后的防治策略上,仍应如强钉螺,尤其是感染性钉螺的控制工作,以从根本上消除和降低血吸虫病的危害。

关 键 词:血吸虫病  监测  疫情  钉螺  江苏省

Abstract:  Objective  To understand the status of Oncomelania snails and infected Oncomelania snails in Jiangsu Province so as to give the scientific evidence for schistosomiasis control policy-mak- ing. Methods  According to the scheme of the National Schistosomiasis Surveillance and the scheme of the Jiangsu Provincial Schistosomiasis Surveillance, 82 schistosomiasis surveillance sites (villages) were selected and established, and the distributions of snails and infected snails were in- vestigated. Results   The snails were found out in 42 surveillance sites (51. 22%) and the infected snails were found out in 10 sites  (12. 20%).  Among all the areas investigated, the percentage of snail areas was 27. 86% and the percentage of infected snail areas was 17. 53%.  The mean density of snails was 0. 16/0. I mz and the mean density of infected snails was 0. 000 44/0. 1 m2.  Conclu- sions   The status of snails in Jiangsu Province is not so optimized, which may become the main re- stricted factor for achieving the aim of schistosomiasis transmission control in the whole province in 2010. So snail control, especially infected snail control, is still the emphasis of schistosomiasis con- trol program.
Keywords:   Schistosomiasis  Surveillance  Endemic situation  Oncomelania snail  Jiangsu Province
