摘要
目的了解和掌握江苏省居民和家畜血吸虫感染情况,为制订防治规划提供科学依据。方法根据全国和江苏省第三次血吸虫病流行病学抽样调查方案,对江苏省未达血吸虫病传播阻断标准的村,采用分层整群随机抽样法进行居民和家畜血吸虫感染情况调查。结果在全省1040个未达血吸虫病传播阻断标准村,抽样调查了13个村,抽样人口比例为1.17%。全省未达传播阻断地区的加权平均感染率为0.131%,推算粪检阳性病人约为3026人。流动人群粪检阳性率为4.95%。结论江苏省未控制的江滩地区和局部内陆通江河道地区,居民感染率仍相对较高。和第二次流行病学抽样调查相比,未控制水网地区疫情下降明显,而未控制江滩地区疫情却有较大幅度的上升,这两类地区是江苏省当前血防工作的重点。
Objective To understand the current endemic status of schistosomiasis, in order to provide scientific basis for decision-making of preventing and controlling plan. Methods According to the third plan of national-wide sampling survey of schistosomiasis, the infection of Schfstosoma japonlcum was investigated with the stratified random sampling method in residents and livestock of transmission areas and transmission controlled areas, Jiangsu Province. Results A total of 13 villages were selected from 1 040 endemic villages, and the proportion of sampling population was 1.17%. The average weight infection rate was 0. 131%, so it was estimated that there were 3 026 persons of positive stool examination. The positive rate of stool examination was 4.95% in the floating population. Conclusion The infection rate was relatively high in marshland and lake and plain regions in transmission areas. Compared with the second schistosomiasis sampling survey, the morbidity of schistosomiasis decreased significantly in plain regions of transmission areas, but it increased significantly in marshland and lake regions, so these regions should be the focus in current control project.
