三峡库区外来流动人口血吸虫感染调查
|
摘要
2006-2009年,采用酶联免疫吸附试验(ELISA)和改良加藤法(Kato-Katz)对三峡库区1986人名外来流动人口进行了血吸虫感染状况调查。结果表明该人群血清学阳性率为1.31%(26/1986);其中来自血吸虫病非流行区、传播控制区和未控制流行区者血清学阳性率分别为0.91%、1.07%和2.18%;血检阳性者中未发现病原学检查阳性者,但其中8例有血吸虫病病史。外来人员来源地以湖北、湖南、四川为主,分别占37.21%、19.03%、17.77%。提示外来、尤其是周边流行省的流动人口是三峡库区血吸虫病的重要潜在传染源,应加强监测。
A total of 1 986 mobile people in the Three Gorges Reservior area were examined by the methods of enzyme-linked immunosorbent assay(ELISA)and Kato-Katz to understand their infection situation of schistosome in 2006-2009.The results showed that the seropositive rate of the moblie population was 1.31%(26/1 986),and those of people from non-endemic areas,transmission-interrupted areas and uncontrolled areas were 0.91%,1.07%,2.18%,respectively.No positive patients were found in the pathogenic examination,but among whom 8 had schistosomiasis history.The majority of the mobile population came from Hubei,Hunan and Sichuan provinces,which accounted for 37.21%,19.03%,17.77%,respectively.It is suggested that mobile population,especially those from surrounding endmeic areas were important potential source of infection,so the surveillance should be strengthened.
