Objective To understand the schistosomiasis control knowledge,attitude,and practice(KAP),and influenc-ing factors of behaviors among residents in Jiangsu Province,so as to provide the evidence for making effective health education and health promotion models. Methods The probability proportionate to size sampling(PPS)and multi-stage sampling meth-ods were adopted to sample the research objects. A questionnaire survey of schistosomiasis control KAP was conducted in the res-idents of 16 to 69 years old in schistosomiasis endemic areas of Jiangsu Province,and the results were statistically analyzed. Re-sults The total awareness rate of the participants was 95.98%for schistosomiasis control knowledge. The correct rates of atti-tude and practice were 89.06%and 77.43%,respectively. The awareness/correct rates of knowledge,attitude and practice re-duced in turns significantly(χ2=1282.96,P<0.01). The knowledge awareness rate of fishermen and boatmen was 90.98%, but their attitude correct rate was only 53.81%(χ2=120.52,P<0.01). The unconditional logistic regression analysis showed that with the education level increasing,their practice correct rate rose,and the participants with the college degree or above had a higher correct rate compared to illeterate ones(OR=6.411,95%CI:4.896-8.395). The practice correct rate of the fisher-men and boatmen was only 5.1%of the rate of the farmers(OR=0.051,95%CI:0.029-0.091). Conclusions The total aware-ness rate of basic knowledge of schistosomiasis prevention and control in the residents of Jiangsu Province has reached the re-quirements in the"National Schistosomiasis Control Long-term Planning Outline(2004-2015)",but the correct rate of behav-iors is low. The education level,occupation and residential areas affect the health behaviors of schistosomiasis prevention and control. Therefore,it is necessary to carry out targeted health promotion activities to promote the formation of healthy lifestyle and behaviors.

Objective To evaluate the effect of the water conservancy schistosomiasis control projects combined with mollus-cicide to control Oncomelania hupensis snails in the rivers connecting with the Yangtze River. Methods The water conservancy schistosomiasis control projects of Zhujiashan River,Qili River and Gaowang River were chosen as the study objects in Pukou District,Nanjing City. The data review method and field investigation were used to evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control O. hupensis snails. Results After the projects of the wa-ter level control and concrete slope protection and mollusciciding were implemented,the snails in the project river sections were completely eliminated. The snail diffusion did not happen in the inland irrigation area too. In the outside of the river beach , though the snails still existed,the snail densities plunged below 1.0 snail per 1.0 m2. Conclusion The comprehensive mea-sures of the combination of water level control,concrete slope protection and mollusciciding can effectively control and eliminate the snails,and prevent the snails from spreading.

Objective To understand the forming cause of the Oncomelania hupensis snail-existent non-endemic areas of schistosomiasis(SENEAS),and to verify the conclusion of previous studies,so as to provide the evidence for schistosomiasis monitoring in such areas in Nantong City,Jiangsu Province. Methods The controlled field tests were carried out to observe the O. hupensis snails artificially infected by schistosome miracidia in SENEAS. The influence of the soil from SENEAS and the en-demic areas on O. hupensis snails artificially infected by miracidia were observed. Results All the experimental snails could be infected by schistosome miracidia except the smooth-shell snails from Tangyuan Village in the controlled field test environment of SENEAS or the endemic areas. The infection rates of the smooth-shell snails were lower than those of the ribbed-shell snails , but there were no statistically significant differences. The mortality rates of the smooth-shell snails were higher than those of the ribbed-shell snails,which were statistically significant (χ2Xindian = 135.118,χ2Shuangdian = 122.836,χ2Baipu =154.436,χ2Dingyan =138.288,χ2Control=151.923,all P<0.01). There were no significant differences in the infection rates of snails between each test group of the soil from SENEAS and the endemic areas(χ2Rugao=0.071,χ2Rudong=0.216,both P>0.05). Also there was no signifi-cant difference between each test group and the control group without soil(χ2=7.148,P>0.05). Conclusion It is likely to form the spread of schistosomiasis in SENEAS in Nantong City with sufficient amount of infection source of schistosomiasis im-ported. It is still necessary to implement the surveillance of schistosomiasis and O. hupensis snails in Nantong City.
