ABSTRACT
Objective To study the import way of schistosomiasis and the vector snail in Three Gorges Reservoir areas (TGR), so as to provide the reference for the surveillance, early warning of schistosomiasis.Methods A total of 256 movement population in Badong County and Zigui County and 1584 immigrants from TGR to the endemic area of Hubei Province were investigated by questionnaire, and screened by means of IHA and COPT. The farm cattle were surveyed in Badong County and Zigui County. Production of paper mills, the source of papermaking raw material, flowers and trees in gardens were investigated for snail survey. At the same time, current situation of immigrants in TGR was investigated. Social data (statistic yearbook, etc) and policy data of development of TGR were collected. Results No farm cattle from endemic area of schistosomiasis was found. In Hubei reach of TGR, the movenment population were mainly from the endemic area of schistosomiasis in Hubei Province. The positive rate of both IHA and COPY was 0 57%(1/175); the positive rate of both IHA in emigrants from TGR was 1 01%(12/1186). No Oncomelania snail was found in the introduced flowers and trees in garden. In paper mills, no reed from the endemic area of schistosomiasis was found. Migrants′ living and sanitary condition were improved after moving,but the production was not well arranged. Orange industry, travel industry, animal husbandry and fishery should be developed preferentially in the future. Conclusion Migrants from TGR to the endemic area of schistosomiasis and the movement population will be the mainly infection source. The problem on cattle as the infection source should be paid attention. It can't be excluded that snail will enter TGR together with the raw material for paper mills or flowers and trees. To develop orange industry will be good for the control of schistosomiasis; but the development of animal husbandry, fishery and travel industry will increase the risk of import of the infection source and snails to TGR.
