Abstract:

According to“The Scheme of Schistosomiasis Surveillance in Zhejiang Province”，the status of Oncomelania
snails，and the schistosome infection of permanent residents，floating population，and livestock were surveyed in a provincial sur?
veillance site of Shengzhou City，from 2008 to 2011. In 4 years，the area with residual snails was 3 060 m2，and no infected snails
were found among 595 living snails. The positive rate of sero?tests for schistosomiasis of the permanent residents was 0.77%，and
that of the floating population was 1.09%. No schistosomiasis cases were found. In conclusion，the area with residual snails is
small and its distribution is scattered，and we still should strengthen the surveillance of snail status and imported schistosomiasis
cases.
