目的了解广西壮族自治区血吸虫病监测现状。方法人群以酶联免疫吸附试验(ELISA)进行血清学筛查,阳性者再以尼龙绢集卵孵化法进行粪便检查;耕牛以塑料杯顶管孵化法检查;野鼠用解剖法检查病原。每年春秋两季采用系统抽样结合环境抽查法查螺,对查获的钉螺用压片法和逸蚴法检查有无血吸虫感染。结果2002~2007年当地居民血检28165人,阳性417人,阳性率1.5%,粪检5718人无感染者;在流动人口监测中查出11例外源性病人;耕牛粪检21820头,解剖野鼠13894只,未发现血吸虫感染;累计查螺面积12095.1hm2,查出3处残存螺点,面积分别为2.1、1.3、3.3hm2;分别检查钉螺1518、4640只和1785只,并检查和走访螺点周围居民、检查耕牛,未发现血吸虫感染病人和动物。结论广西区血吸虫病监测成效明显,但工作量大,监测策略可作适当调整。
Objective To understand the status of schistosomiasis surveillance in Guangxi Zhuang Autonomous Region. Methods The population was serologically tested by enzyme-linked immunosorbent assay (ELISA), and then the stools were examined by nylon silk hatching method. The cattle were hatched with a plastic cup top hatching method. The pathogen was examined by anatomical method. Spring and autumn every year using systematic sampling combined with environmental checks to check the snail, snail seized by using compression method and check the law whether or not Schistosoma infection. Results From 2002 to 2007, there were 28,165 blood tests of local residents, with a positive rate of 417 and a positive rate of 1.5%. There were no infected persons in 5718 manure samples. Eleven cases of exogenous patients were detected in the floating population. There were 13894 wild voles and no schistosome infection was found. The total snail area was 12095.1 hm2, and three remaining snail spots were found with the area of 2.1, 1.3 and 3. hm2 respectively. 1518, 4640 and 1785 snails were examined, Surrounding residents, check the cattle, did not find schistosomiasis infected patients and animals. Conclusion The monitoring results of schistosomiasis in Guangxi are obvious, but the workload is heavy and the monitoring strategy can be adjusted appropriately.
