[Investigation of Oncomelania hupensis snails in Anhui Province in 2016].

OBJECTIVE: snails in Anhui Province in 2016, so as to provide the evidence for formulating the 13th Five-Year Plans for Schistosomiasis Control.

The map showed that the most environments with snail habitats were distributed along the Yangtze River in Anhui Province. CONCLUSIONS: For the first time, the investigation has built the database and map of snail spatial distribution, which truly reflect the historic and current status of snail distribution in Anhui Province and can provide the evidence for formulating the 13th Five-Year Plans for Schistosomiasis Control and improving the schistosomiasis prevention and control work in the future.
