Abstract
What is already known about this topic? Oncomelania hupensis (O. hupensis) is the only intermediate host of Schistosoma japonica. The distribution of O. hupensis is affected by a series of climate, geographical, sand ocioeconomic factors, which reflect the risk areas of schistosomiasis. What is added by this report? There were certain geographical aggregations in the potential high distribution areas of O. hupensis, which were mainly distributed in Poyang Lake area, Dongting Lake area, and the middle and the lower reaches of the Yangtze River. What are the implications for public health practice? Monitoring and forecasting the distribution of O. hupensis is conducive to improving the early warning capabilities of the potential risk of schistosomiasis transmission and progressively promoting the elimination of schistosomiasis nationwide.
