Abstract

OBJECTIVE

To understand the correlation between schistosomiasis endemic situation and Oncomelania snail status, and discuss the control strategy and measures.

METHODS

With a retrospective research method, the data were collected and analyzed including the snail area, infected snail area, snail density, density of infected snails, the infection rate of snails, the positive rates of blood tests and stool examinations for schistosomiasis in residents and domestic animals, and the incidence of acute schistosome infection in Yizheng City from 2002 to 2011. The correlation between the infected snails and schistosomiasis was analyzed.

RESULTS

There were decline trends in snail area, infected snail area, and schistosomiasis situation. There were positive correlations between the infected snail area and snail area (r = 0.732, P < 0.05), the occurrence of acute schistosomiasis patients and infected snail area (r = 0.678, P < 0.05), and the snail area and schistosome infection rate of residents (r = 0.774, P < 0.05).

CONCLUSION

In order to control schistosomiasis, we need to control infected snails, reduce snail areas, and implement comprehensive control measures.

摘要

目的

了解血吸虫病流行状况与钉螺现状的相关性，探讨防治策略与措施。

方法

采用回顾性研究方法，收集并分析2002年至2011年仪征市的钉螺面积、感染性钉螺面积、钉螺密度、感染性钉螺密度、钉螺感染率、居民和家畜血吸虫病血检与粪检阳性率以及急性血吸虫感染发病率等数据。分析感染性钉螺与血吸虫病之间的相关性。

结果

钉螺面积、感染性钉螺面积和血吸虫病疫情呈下降趋势。感染性钉螺面积与钉螺面积之间存在正相关（r = 0.732，P < 0.05），急性血吸虫病患者的发生与感染性钉螺面积之间存在正相关（r = 0.678，P < 0.05），钉螺面积与居民血吸虫感染率之间存在正相关（r = 0.774，P < 0.05）。
