目的 分析 1991/ 1999江宁县血吸虫病流行及钉螺分布状况的变化情况及两者之间的关系 .方法 用描述流行病学方法进行分析 .结果 江宁县 1991/ 1999血吸虫患者群检出率呈明显下降趋势 ,然而同期钉螺面积变化呈徘徊态势 .江滩是江宁县钉螺的主要分布区域 ,占总钉螺分布面积的95 % ,江滩型钉螺密度明显大于山地型 (P<0 .0 1) ,江滩地区血吸虫病检出率明显高于山地地区 (P<0 .0 5 ) .在一定时期(1991/ 1998) ,该县血吸虫病的流行与有螺面积、钉螺密度变化密切相关 (r分别为 :0 .776 ,0 .896 ,P均 <0 .0 5 ) .结论 江滩地区仍是血防工作的重点地区 。
AIM To analyze the change of Schistosomiasisprevalence and schistosomiasis transmitted snail status in Jiangning County from 1991 to 1999, and to explore the relationship between Schistosomiasis prevalence and the snail status. METHODS Describing methods of epidemiology were used. RESULTS The detectable rate of Schistosomiasis in Jiangning County from 1991 to1999 showed an obvious downtrend, but the area of snail distribution lingered on at the same time. Marshland was the main region for snail distributing, accounting for about 95 percent of snail distribution area in Jiangning County, and the snail density in marshland was evidently bigger than that on mountain ( P <0.01). The detectable rate of Schistosomiasis in marshland was evidently higher than that on mountain ( P <0.05). Schistosomiasis prevalence was correlated positively with the area of snail and the snail density ( P <0.05). CONCLUSION Marshland is still the chief region for prevention of schistosomiasis, where the snail status is badly controlled.
