<abstract abstract-type="Summary"> <sec> <b>What is already known about this topic?</b> No live specimens of the snail <i>Oncomelania hupensis</i> (<i>O. hupensis</i>) and indigenous infected cases of schistosomiasis japonicum have been found in Guangdong Province since 1993, but live <i>O. hupensis</i> was found again in 2019. This study conducted <i>O. hupensis</i> identification and elimination. </sec><sec> <b>What is added by this report?</b> In 2019, live <i>O. hupensis</i> specimens were detected by routine surveillance in areas in Qujiang of Shaoguan City and Yingde of Qingyuan City, and an emergency response was launched immediately. </sec><sec> <b>What are the implications for public health practice?</b> The suspected habitat of <i>O. hupensis</i> in originally endemic areas of schistosomiasis in Guangdong is still complicated, so it is necessary to record suspected habitats comprehensively and carry out scientific routine surveillance for <i>O. hupensis</i>. </sec>
