湖北省2010年血吸虫病疫情国家监测点监测结果分析

Analysis on the endemic situation of schistosomiasis in the national surveillance site in Hubei province(2010)

目的分析湖北省2010年国家级血吸虫病疫情监测点疫情变化,了解湖北省血吸虫病流行现状,为制定血吸虫病防治对策提供科学依据。方法根据《全国血吸虫病监测方案》的要求,对16个监测点开展监测工作,并统计分析各项指标。结果湖北省16个监测点居民感染率为0.89%,耕牛感染率为1.41%,活螺平均密度为0.324 0只/0.11 m2,感染螺平均密度为0.000 19只/0.11 m2,钉螺感染率为0.059%。各项疫情指标较前4年有所下降。结论监测点人畜感染率呈现持续下降,但部分监测村钉螺感染率仍较高,因此,应加强钉螺控制措施,提高药物灭螺质量,防止疫情反弹。

Objective To analyze the endemic situation of schistosomiasis in the national surveillance sites in Hubei province in 2009,and understand the endemic status of schistosomiasis transmission in Hubei,so as to provide basis for establishing prevention and control program.Methods Surveillance was carried out in 16 national surveillance sites in Hubei province according to the national surveillance protocol.Data statistics and analysis were processed by SPSS 12.0.Results In the 16 surveillance sites,the infection rate of residents was 0.89%,the infection rate of cattle was 1.41%,snail density was 0.324 0/0.11 m2,the density of positive snail was 0.000 19/0.11 m2 and snail infection rate was 0.059%.The endemic indices of 2009 were lower than those of the past four years.Conclusions The infection rate of residents and cattle continuously declined in the 16 surveillance sites,while the infection rate of snail was still very high.Therefore,the measure for snail control should be enhanced,and the quality of molluscicide must be improved to prevent the relapse of the endemic.
