ABSTRACT
Objective To analyze the endemic situation of schistosomiasis after its interruption of transmission in Xiuzhou District,Jiaxing City,Zhejiang Province,so as to provide the references for future surveillance work. Methods The data of schistosomiasis and Oncomelania hupensis snails in Xiuzhou District were collected and analyzed statistically. Results From 1994 to 2015,totally 975 village?times were investigated for O. hupensis snails,and the accumulated area of 4 385.31 hm2 was surveyed. Twenty former snail sites were reoccurring,with an area of 32.61 hm2. An area of 57.71 hm2 was supplied with snail eradication measures. Totally 11 941 snails were dissected and no schistosome infected snails were found. The serum and stool tests were performed to 221 794 and 3 731 residents respectively,and no local infection cases but four imported cases were found. Conclusion The endemic situation of schistosomiasis in Xiuzhou District is stable after the transmission was interrupt?ed. However,there are imported schistosomiasis cases,and therefore,the prevention of imported infection source is the focus of surveillance work.
