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 control effect of 19 schistosomiasis control counties (cities and districts) in Hubei Province in 2013. Methods According to the principle of cluster random sampling, the appraisal villages were randomly selected in each county under examination, and on-the-spot assessment was conducted on the population condition, livestock condition, snail control, prevention and control of acute infection, and health education. RESULTS: A total of 29631 seropositive women were enrolled in this study, with a positive rate of 6.98% (0.78% ~ 16.47%). A total of 2 021 were positive for stool samples and 47 were positive. The infection rate was 0.16% (0 ~ 0.82%). The main livestock in 19 counties are all cattle, of which 17 were implemented as machine-managed cattle in 2013. In Caidian District and Huangpi District, 105 cattle were dung checked, and no positive results were found for schistosome eggs. A total of 154 environments were surveyed on site with a survey area of 1 579.37 hm ~ 2. A total of 31 829 boxes were surveyed and 4 857 snails were caught, of which 1 935 live snails. Infected snails were not found on the anatomy. Since 2009, all the 19 assessed counties have established blood and anti-crime records with administrative villages as a unit that can reflect the local schistosomiasis condition and the changes in snails. Conclusion The 19 counties (cities and districts) in Hubei Province all reached the standard of schistosomiasis control.
