Abstract: Objective To evaluate the effect of schistosomiasis control in “Oriental Star shipwreck event” in Jianli County， Hubei Province， so as to provide experiences for schistosomiasis prevention and control in rescue of emergency in the future. Methods According to the data of historical schistosomiasis prevalence and the results of the field survey in the townships in the upstream and downstream of the rescue spots， the emergency handling measures of schistosomiasis control were evaluated. Meanwhile， the Oncomelania hupensis snail situation， priority crowd chemotherapy， key aquatic monitoring， and illness monitoring of people and livestock were investigated to evaluate the schistosomiasis control effect after the events comprehensively. Results There were no schistosome?infected snails found in the place of shipwreck and the rescue spots. The average density of O. hupensis snails in 5 townships of Jianli County was 0.064 snails/0.1 m2 ， and there were no infected snails found. The positive rate of 2 090 migrants in the schistosomiasis serologic tests was 0.29% and there were no positive ones found in the fecal examination. There were no acute schistosomiasis cases found by the sentinel surveillance fever clinics， and also no positive cattle were found.
