【摘要】 初期采用以查清残存螺点和遗留病人为重点，同时，进行新感染调查的策略。后来调整为对原疫区外围和毗邻地区进行螺情监测及防止外来传染源输入。８年来监测查螺面积１１６５２２１５３ｍ￣２，查出１３个残存螺点，面积２０２６ｍ￣２，无阳性钉螺。采用ＩＨＡ、ＣＯＰＴ和ＥＬＩＳＡ方法对疫区人群检测，有病史人群的阳性率分别为８．３５％、７．２０％和１３．０８％，无病史人群为３．２４％、３．４０％和５．４７％，前者高于后者。对幼龄耕牛粪检５５８７４头，全部阴性。结果表明，广西血吸虫病监测措施是行之有效的。更多还原

【Abstract】 This paper reports the results of schistosomiasis surveillance in Guangxi.At the earlystage, the surveillance was carried out by checking the residual snails,detecting the residual patientsand new infections. The strategy was changed later. The method of surveillance was to check snails inthe periphery areas of previous endemic areas and the adjacent areas. In the meantime,the imported in-fection sources were also detected.A total of 116 522 153 square meters in the previous endemic areaswere checkedfor 8 successive vears,and 13 foci of residual snails were found. The total area of residualsnails foci was 2 026 square meters but no positive snails was found.The population with and withoutinfection history were tested by IHA,COPT and ELISA.The antibOdy positive rates of the populationwho had infection history were 8. 35%,7.20%and 13.08% respectively,while those of the populationwho did not have infection history were 3.24%,3.40%and 5.47% respectively,which were lowerthan the former group.However,all the antibedy一positive people were found negative by stool exami-nation.A total of 55 874 young cattle were also tested by stool examination but all of them were nega-tive. The results indicated that these surveilance measures were useful and successful.更多还原
