Abstract:
Objective To understand the risk situation of imported schistosomiasis and its main influencing factors in Shang-hai City from 2005 to 2015. Methods A retrospective survey was performed,and the database was established based on the da-ta collection of imported schistosomiasis,Oncomelania hupensis snail situation and mobile population in Shanghai City from 2005 to 2015. Results From 2005 to 2015,the mobile population in Shanghai City increased by 123.92％,which reached about 9816500,and 54.70％of them were located in the inner suburban districts. The accumulated areas with snails of 7.13 hm2 were found in 16 towns of 4 outer suburbs(excluding Chongming District). A total of 23 cases of imported schistosomiasis were found in Shanghai City,and the number of the imported schistosomiasis cases was on the downward trend(rs=-0.782,P=0.004). From 2005 to 2009,11 out of 13 imported schistosomiasis cases(84.62％)were distributed in the inner suburban dis-tricts where no O. hupensis snails were found at the same time. From 2010 to 2015,9 out of 10 imported schistosomiasis cases (90％)were distributed in the outer suburban districts where O. hupensis snails were found at the same time. Conclusion The number of imported schistosomiasis cases in Shanghai is on the downward trend. However,the threat of imported schistosomiasis to the prevention and control of schistosomiasis in Shanghai City should not be ignored.
