There was a negative correlation between densities of living snails and years (r=-0.809,P<0.01).2.Residents and students’ knowledge about schistosomiasis prevention awareness rate increased year by year.The rate of students,and citizens’ knowledge of schistosome on prevention of the disease increased from72.2%and77.9%to96.58%and92.83%from2000to2010,respectively. The correlation analysis show that there was a negative correlation between students’ and residents knowledge about schistosomiasi between years(r=0.973, P<0.001, r=0.963, P<0.001).3.The direct economic burden of advanced schistosomiasis in Jurong City was489634Yuan,and the indirect economic burden was632237Yuan.The mean assistance fee for advanced schistosomiasis patients was5000Yuan per capita at present.In the questionnaire survey,77.2%of the patients thought that advanced schistosomiasis had certain impact on their family and psychology.The satisfaction degree in all sides were above85%.Nevertheless,83.5%of the patients still had certain aspects of demands that were urgent to be solved besides the assistance.Conclusions1.Taking with comprehensive prevention of control snail using niclosamide drugs can control the transmission of schistosomiasis obviously in Hilly Area.The comprehensive prevention and control of control snail,human and animal screening chemotherapy is significant.Control snail and chemotherapy is the most direct and effective measures to prevent and control schistosomiasis.2.Advanced schistosomiasis has certain impact on the family and social economics in Jurong City.To reduce the burden mostly depend on the concems from the govermentand the effective performance of the control programme as well as implementation of the assistance approaches.
