摘要
目的分析评价实施以控制传染源为主的综合防治策略两年的初期效果,以优化防治策略。方法从2005年实施了以控制传染源为主的综合防治措施的秋浦河流域16个血吸虫病流行村中,随机抽取疫情未控制和控制村各3个,调查比较2005和2006年的螺情和病情。结果阳性螺密度疫情未控制村和控制村分别由2005年的0.091只/0.11m2、0.0028只/0.11m2降至2006年的0.0048只/0.11m2、0.0004只/0.11m2;钉螺感染率疫情未控制村由2005年的0.24%降至0.11%,差异有统计学意义(χ2=8.769,P=0.003);疫情控制村由0.30%降至0.05%,无统计学差异(χ2=3.193,P=0.074)。疫情未控制村和控制村人群血吸虫感染率分别由2005年的5.86%、3.67%下降至2006年的2.28%、0.95%,差异均无显著性(P>0.05)。结论初期观察表明以控制传染源为主的综合防治措施能进一步控制秋浦河流域的血吸虫病疫情,尤其是在降低滩地污染上。
Objective To access the elementary effects on schistosomiasis control after carrying out the strategies of infectious sources control for two years, aim to optimize the controlling strategy. Methods 6 villages, including 3 uncontrolled and 3 under control villages, were randomly selected from 16 epidemic villages which are located at Qiupu River basin and being implemented the control strategy in 2005. Snail situation and infection rate of human and cattle were surveyed in 2005 and 2006. Results The density of positive snail in the uncontrolled and under controlled epidemic villages decreased from 0.091/0.11m^2 and 0.0028/0.11m^2 to 0.0048/0.11m^2 and 0.0004/0.11m^2 respectively. The infection rate of snails reduced from 0.24% to 0.11% with statistical significance (χ^2=8.769,P=0.003)in the uncontrolled epidemic villages, and from 0.3%to 0.05% with no significant difference in the under controlled ones. The average infection rate of schistosomiasis decreased from 5.86% to 2.28% in the uncontrolled epidemic villages, and from 3.67% to 0.95% in the under control epidemic villages with no significant difference (P〉0.05). Conclusion The comprehensive measures with controlling the infectious source as predominance was an effective strategy to control schistosomiasis, especially to reduce the contamination on the marshland.
