[Strategy of solidification and surveillance for schistosomiasis in transmission-interrupted provinces in China].

In schistosomiasis transmission-interrupted provinces in China, the endogenous source of infection has been basically cleared, and the exogenous source of infection is considered as a major threat. The residual snail area has been increasing in different degrees, and imported snails are regarded as a potential risk. So the possibility of schistosomiasis recrudescence still remains. According to the endemic characteristics, the integrated solidification strategy with emphasis on control of residual snails and imported cases should be taken in the future.
