传播阻断地区流动人口对血吸虫病传播的影响

目的探讨传播阻断地区流动人口对血吸虫病传播的影响。方法收集黄山市1994～2006年流动人员血吸虫病监测资料,现场调查外出、外来务工人员血吸虫感染情况,并对外来务工人员居住地进行螺情调查。结果1994～2006年全市共查出流动人员血吸虫病人10例,本次调查外出、外来务工人员血检阳性率分别为0.49%和0.47%,粪检均未查出血吸虫病人。外来务工人员居住地查出有螺面积3 000 m^2,未发现感染性钉螺。结论流动人口对传播阻断地区的血吸虫病传播具有一定影响。应加大对流动人口的监测和健康教育力度,防止外来传染源输入。

Impact of mobile population on transmission of schistosomiasis in transmission-interrupted area

The historical surveillance results showed, there were 10 schistosomiasis cases in Huangshan City from 1994 to 2006. The survey in 2007 showed, the positive rates of blood examination for schistosomiasis in migrant workers and immigrant workers were 0.49% and 0.47% , respectively, but no schistosome-infected patients were detected by using the stool examination. An area with snails of 3 000 m~2 was found in the residence of the immigrant workers, but no infected snails were found. It is indicated that the mobile population has some impact on the transmission of schistosomiasis in the transmission-interrupted area. The surveillance and health education for the mobile population should be strengthened, and the imported infectious source should be prevented.
