ABSTRACT
Objective To evaluate the effect of schistosomiasis control in Mianyang City in ten years after Wenchuan earth-quake, so as to provide the experiences for schistosomiasis control post-disaster. Methods The data of implementation of schistosomiasis control work in ten years after the Wenchuan earthquake were collected and analyzed for the epidemic situation of schistosomiasis in Mianyang City. Meanwhile, the awareness situation on schistosomiasis control of villagers and students was investigated by questionnaires in 2008 and 2015. Results All of the 6 counties (cities, districts) with schistosomiasis endemic in Mianyang City were hit by the earthquake disaster. After the disaster, the measurements including the conventional schistosomiasis control measures, the control of exogenous infection sources, the control of Oncomelania hupensis snails, and health education were carried out. The relevant departments of schistosomiasis control were cooperated to implement the prevention and control measures. The schistosomiasis prevalence of population and the snail condition rose in the year of the earthquake, but then declined year by year. In 2015, the awareness rates of schistosomiasis control of both villagers and the students were significantly improved compared with those in 2008. Conclusion The measures of schistosomiasis control after the earthquake disaster are effective in Mianyang City, and the goal to prevent major plague after the earthquake is achieved.

ABSTRACT
Objective To master the dynamics of schistosomiasis endemic situation and influencing factors in Mianyang City,so as to provide the evidence for making the control and prevention measures. Methods Six villages of six schistosomia?sis heavy endemic counties were selected as survey sites according to the national surveillance protocol(Revision in 2014)in Mianyang City. The surveys of the incidences of schistosomiasis in population and livestock as well as the prevalence of Oncome?lania hupensis snails were conducted in the 6 national surveillance sites. Results The serum positive rates of local residents and migrant people were 2.12%and 1.71%,respectively. The infection rate of cattle was 0. The area with snails was 9.344 8 hm2. The mean density of living snails was 0.25/0.1 m2. The occurrence rate of frames with snails was 7.07%,and no infected snails were found. Conclusions The infection rates of schistosome in human and livestock are low and the prevalence of O. hu?pensis snails is stable in the national surveillance sites in Mianyang City. However,the schistosomiasis transmission risk still ex?ists,therefore,we should strengthen the control measures to prevent the rebound of the endemic.
