目的掌握全国血吸虫病疫情监测点镇江市丹徒区三洲村疫情变化情况。方法按《全国血吸虫病监测方案》方法,2008年在监测区内开展螺情、病情等疫情监测。结果2008年共查出有螺面积27 hm2,其中感染性钉螺面积14hm2,活螺密度为0.86只/0.1 m2,感染性钉螺密度为0.002 1只/0.1 m2,钉螺感染率为0.25%。查出间接血凝试验阳性28例(3.10%),粪检阳性9例,人群血吸虫感染率为1%,未查见粪检阳性家畜。2008年监测点内未发现急性血吸虫病病例和新发晚期血吸虫病病例。结论监测区内血吸虫病疫情较稳定。江滩灭螺工作要结合环境改造进行综合治理,以传染源控制为主的综合防治措施仍需进一步加强。
Objective To understand the epidemic situation of schistosomiasis in Sanzhou Village, Dantu District, Zhenjiang City, China. Methods According to the “national schistosomiasis surveillance program” approach, in 2008 to carry out spirits in the surveillance area, the disease and other epidemics monitoring. Results In 2008, a total area of 27 hm2 was found. The infective snail area was 14hm2, the live spiral density was 0.86 /0.1 m2, the infective snail density was 0.002 1 /0.1 m2, and the snail infection rate was 0.25%. Indirect hemagglutination test was positive in 28 cases (3.10%), stool positive in 9 cases, the crowd of schistosome infection rate was 1%, did not see the stool positive animals. No cases of acute schistosomiasis and new advanced schistosomiasis were found in the monitoring sites in 2008. Conclusion The epidemic situation of schistosomiasis in the monitoring area is relatively stable. The project of eliminating snails on riverside should be integrated with the environmental improvement and comprehensive prevention and control measures based on infection source control still need to be further strengthened.
