The Potential Distribution Prediction of <i>Oncomelania hupensis</i> Based on Newly Emerging and Reemergent Habitats — China, 2015−2019

Abstract

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