Impact of mobile population on transmission of schistosomiasis in transmission-interrupted area / 中国血吸虫病防治杂志

ABSTRACT

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.
