Abstract:
Objective To understand the impact of Qionghai Lake wetland ecological protection construction on the preva?lence of schistosomiasis,so as to provide the evidence for formulating the strategies for schistosomiasis control and prevention. Methods A retrospective survey of the construction of Qionghai Lake wetland was performed,and eleven villages around the wetland were surveyed for schistosomiasis endemic situation. The influence of the wetland project on the schistosomiasis preva?lence and Oncomelania hupensis snail status were investigated. Results Before the construction of Qionghai Lake wetland,the snail elimination and extended chemotherapy for residents was performed. After the project was finished,the roads and ditches were hardened. From 2009 to 2014,the schistosome infection rate of residents declined from 0.37% to 0. No schistosome infect?ed snails were found and in recent 2 years,no snails were found. No mice were infected in the sentinel tests. Conclusions The construction of Qionghai Lake wetland effectively eliminates snails,and interrupts the transmission of schistosomiasis. Howev?er,the environment of the wetland is more suitable for snail breeding,and therefore,the surveillance still should be strength?ened.
