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 m2,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。
Objective To explore the influence of floating population in the blocking area on the transmission of schistosomiasis. Methods The data of schistosomiasis surveillance in migrant workers from 1994 to 2006 were collected from Huangshan City. The outbreak of schistosomiasis among migrant workers and migrant workers was investigated on site. Results From 1994 to 2006, 10 cases of migratory schistosomiasis were detected in the whole city. The survey showed that the positive rates of blood tests of migrant workers were 0.49% and 0.47% respectively, and no schistosomiasis was detected in the manure. Migrant workers found a living area of 3,000 m2 of snails and no infectious snails were found. Conclusion The floating population has some influence on the transmission of schistosomiasis in the areas where the transmission is blocked. Monitoring and health education should be stepped up to prevent the importation of foreign sources of infection.
