2013年湖北省19个县(市、区)血吸虫病传播控制达标考核评估

Evaluation of transmission control of schistosomiasis in 19 counties(cities,districts)of Hubei Province in 2013

目的评估2013年湖北省19个达到血吸虫病传播控制标准县(市、区)的防治效果。方法按照整群随机抽样原则,在每个被考核县随机抽取考核村,对人群病情、家畜病情、螺情、急性感染防控和健康教育等方面进行现场考核。结果共计血清学检查29 631人,阳性2 068人,阳性率6.98%(0.78%~16.47%);血检阳性者粪检2 021人,检出阳性47人,感染率为0.16%(0~0.82%)。19个县主要家畜均为耕牛,其中17个已于2013年实施以机代牛。对蔡甸区、黄陂区105头耕牛进行粪检查病,未查出血吸虫卵阳性。现场抽查了154个环境,调查面积1 579.37 hm^2,共调查31 829框,捕获钉螺4 857只,其中活螺1 935只,经解剖未发现血吸虫感染性钉螺。2009年以来,19个被考核县均建立了以行政村为单位,能反映当地血吸虫病病情、螺情变化的血防档案资料。结论湖北省19个被考核县(市、区)均达到了血吸虫病传播控制标准。

Objective To evaluate the schistosomiasis transmission control in 19 counties（cities,districts）of Hubei Province in 2013. Methods The epidemic villages from different counties were randomly sampled by the cluster sampling method as the evaluation villages. The schistosome infection status of human and livestock,the Oncomelania hupensis snail status,the documents and data of schistosomiasis control,acute infection control and health education were investigated in the field.Results The serum examination of schistosome infection was performed to 29 631 residents,and 2 068 were positive,with a positive rate of 6.98%（0.78%-16.47%）. The stool examination was performed to 2 021 sero-positive persons,and 47 cases were stool-positive,with an infection rate of 0.16%（0-0.82%）. The cattle was the main domestic animals in 19 counties（cities,districts）,and the measures of replacing cattle with machine for cultivation were done in 17 counties（cities,districts）. Totally105 cattle in Caidian District and Huangpi District received stool examinations and no positives were detected. A total of 1579.37 hm^2 and 31 829 frames in 154 environments were surveyed,and 4 857 snails were collected. Of the 1 935 living snails dissected,no infected snails were detected. The files regarding the schistosomiasis morbidity and snail status have been established in 19 counties（cities,districts）since 2009. Conclusion The transmission of schistosomiasis in 19 counties（cities,districts）of Hubei Province has reached the standard of transmission controlled.
