[Surveillance of schistosomiasis of reconstruction personnel after earthquake in Mianzhu City from 2009 to 2011].

After "5.12" earthquake, 5 128 reconstruction people from schistosomiasis endemic areas were surveyed for schistosome infection from 2009 to 2001. There were 261 seropositive persons with the positive rate of 5.09%, but there were no persons with positive stool examination. The seropositive rate was higher in reconstruction persons from schistosomiasis endemic areas than that in local residents, therefore, we still should strengthen the active schistosomiasis surveillance of reconstruction people from schistosomiasis endemic areas in order to prevent input of infection source so as to consolidate the achievements of schistosomiasis control.
