Abstract: Objective To explore the relationship between schistosome serum test positive rate of residents and positive rate of Oncomelania snails in a national schistosomiasis surveillance site of Jiangling County. Methods According to the national schistosomiasis monitoring scheme，the data of surveillance including the schistosome serum test positive rates of residents and positive rates of Oncomelania snails from 2005 to 2011 were collected and analyzed statistically. Results From 2005 to 2011， the schistosome serum test positive rates of residents were 26.09%，11.84%，10.37%，10.09%，12.08%，9.61%，and 6.00%，re? spectively；the schistosome positive rates of Oncomelania snails were 0.36%，0.08%，0.15%，0.129%，0.067%，0.091%，and 0.045%，respectively. There was a significant positive correlation between them（r = 0.929，P < 0.01） . Conclusion There is a positive correlation between schistosome serum test positive rate of residents and positive rate of Oncomelania snails. Therefore， we should strengthen the snail control.

摘要：

目的 探讨江陵县国家血吸虫病监测点居民血检阳性率与钉螺感染率的关系。方法 按照 《全国血吸虫病监测方案》 的要求开展血吸虫病监测， 收集2005-2011年监测点居民血检阳性率、 钉螺感染率等指标， 用Pearson相关分析对两者关系进行评估。结果 2005-2011年监测点居民血检阳性率分别为26.09%、 11.84%、 10.37%、 10.09%、 12.08%、 9.61%、 6.00%， 钉螺感染率分别为0.36%、 0.08%、 0.15%、 0.129%、 0.067%、 0.091%、 0.045%， 两者间存在显著正相关 （r = 0.929， P < 0.01）。结论 江陵县国家血吸虫病监测点居民血检阳性率与钉螺感染率成正相关关系， 应加大钉螺尤其是感染性钉螺控制力度， 以保障疫区居民身体健康。
