Abstract:

Oncomelania hupensis is the only intermediate host of Schistosoma japonicum， and it has a significant influence on the transmission， control and elimination of schistosomiasis. In 2016， Zhejiang Province passed the national united assessment of “maintaining the schistosomiasis elimination status”; however, there are still O. hupensis snails remained in the very complicated environments. The breeding and spread of O. hupensis snails can be controlled for a long time with the environmental modification by adapting to local circumstance and scientific development， which can reduce the potential risk of schistosomiasis transmission and promote the development of local economy and society. This paper analyzes the working conditions of schistosomiasis prevention and control in Zhejiang Province and gives some relevant suggestions on how to guarantee the maintenance of the schistosomiasis elimination status in Zhejiang Province by the environmental modification combined with “a total of five?water treatment”， which can effectively condense the local snail breeding environments in key schistosomiasis endemic regions.
