目的分析了解公安县血吸虫病国家监测点血吸虫病疫情状况。方法按照《全国血吸虫病监测方案》的要求,每年在张家湖村监测点开展螺情和人畜病情的调查与检测,计算疫情指标并进行统计分析。结果 2004-2013年张家湖村人群血吸虫感染率分别为10.66%、7.86%、4.29%、2.48%、1.09%、1.09%、0.91%、0.56%、0.75%、0.58%,耕牛感染率分别为12.75%、10.22%、9.24%、3.88%、0、2.72%、1.98%、1.86%、0.78%、0,总体均呈下降趋势;与2004年相比,2013年人群感染率下降了94.75%,且完全消除了散放耕牛现象。2004年监测点有螺面积19.3 hm2,2007年以来降至并维持在6.3hm2,有螺面积减少了67.36%,2004年查出感染性钉螺面积0.1 hm2,自2005年起未查到感染性钉螺;2004年活螺平均密度0.99只/0.1 hm2,2013年为0.07只/0.1 hm2,下降了92.93%。结论张家湖村近10年来血吸虫病疫情大幅下降,取得了较好的防治效果。
Objective To analyze and understand the epidemic situation of schistosomiasis at the national monitoring point of schistosomiasis in Gong’an County. Methods According to the requirements of “National Schistosomiasis Surveillance Program”, the investigation and detection of snail and human and animal diseases were carried out every year at the Zhangjiahu village monitoring sites, and the epidemic index was calculated and statistically analyzed. Results The infection rates of schistosomiasis in Zhangjiahu village from 2004 to 2013 were 10.66%, 7.86%, 4.29%, 2.48%, 1.09%, 1.09%, 0.91%, 0.56%, 0.75% and 0.58% Compared with 2004, the infection rate in population decreased by 94.75% in 2013 compared with that in 2004, and the rate of population infection decreased by 94.5% And completely eliminate the phenomenon of loose cattle. In 2004, the monitoring area had a spiral area of 19.3 hm 2. Since 2007, the average area of this area was 6.3 hm 2 and the area of snails reduced by 67.36%. In 2004, the area of infectious snails was found to be 0.1 hm 2. No infective snails were found since 2005 In 2004, the average density of live snails was 0.99 / 0.1 hm2 and in 2010 it was 0.07 / 0.1 hm2, a decrease of 92.93%. Conclusion The epidemic situation of schistosomiasis in Zhangjiahu Village has been greatly reduced in the past 10 years and a good control effect has been achieved.
