It is engineering to lead water from one river region to another. In order to control endemic area expanded and provide control measures, the paragonimiasis was investigated in the regions concerned. Methods The infection situation of population, intermediate host, reservoir host and breed place of intermediate host were investigated in concerned regions. Results In source region, there were no patients, skin test positive rate of population was 1.9%. First and second intermediate host was not found in most river. Reservoir host was not infected. River bed structure was adapted to reproduce of intermediate host. The region of reception water was not endemic area of paragonimiasis. Conclusion In the source region, prevalent of paragonimiasis tend to end. There is not reservoir host infected, endemic area is getting weak. There are breeding place for intermediate host, and first and second intermediate host of paragonimus in some river. To prevent extension of endemic area of paragonimiasis, it is necessary measures to control shift of Semisulcospira liberitina for diverting water engineering.Read More
