METHODS: The schistosome infection status of human, cattle, sheep and Oncomelania hupensis snails and costs of control measures were gathered during the period of 2006 to 2016. The costs for different periods and cost-effectiveness ratios were calculated.
RESULTS: The prevalence of schistosome infection in residents in the pilot villages decreased from 3.44% in 2006 to 0 in 2016. The annual costs of schistosomiasis prevention and control were 4 708 500 yuan from 2006 to 2008, 5 094 700 yuan from 2009 to 2012 and 9 522 700 yuan from 2013 to 2016. The cost-effectiveness analysis showed that the average annual cost of reduction in the residents\'infection rate by 1% were 79 500 yuan from 2006 to 2008, 101 200 yuan from 2009 to 2012, and 95 200 yuan from 2013 to 2016, respectively.
CONCLUSIONS: The comprehensive schistosomiasis control strategy with focus on cattle and sheep removal in Junshan District is cost effective which could be extended to other lake and marshland schistosomiasis endemic areas.
[摘要]目的 评价湖南省岳阳市君山区以全面淘汰牛羊为重点的血吸虫病综合防治措施的成本效果。 方法 回顾性 收集2006-2016年君山区试点村淘汰牛羊、查治病、查灭螺及各项血防经费投入等资料, 统计各项血防措施的成本, 计算 不同时期的成本效果比。 结果 2006-2016年君山区试点村居民血吸虫感染率从3.44% 下降至0, 血防工作共投入 7 259.48万元。2006-2008、2009-2012年和2013-2016年三个阶段的年平均血防成本分别为470.85万、509.47万元和 952.27万元。成本-效果分析显示, 2006-2008、2009-2012年和2013-2016年三个时期居民血吸虫感染率每下降1%的年 均血防成本分别为7.95万、10.12万元和9.52万元。 结论 君山区采取的以全面淘汰牛羊为重点的血吸虫病综合防治措 施取得了良好的防治效果, 可向其他湖沼型血吸虫病流行区推广。.
