Abstract: Chengdu⁃Chongqing economic circle is centered on Chengdu City and Chongqing Municipality, with aims to build the "fourth growth pole" of China's economy. During this circle, elimination of schistosomiasis had been achieved in 82.5% of the endemic counties (districts) of Sichuan Province, and schistosomiasis is not historically endemic in Chongqing Municipality; however, there is still a risk of schistosmiasis transmission in Sichuan Province and Chongqing Municipality because the natural and social factors affecting schistosomiasis transmission have not been completely eliminated in these areas. Based on the endemic situation of schistosomiasis in Sichuan Province and Chongqing Municipality, we analyzed the opportunities and challenges of schistosomiasis control during the construction of Chengdu⁃Chongqing economic circle, and proposed the corresponding suggestions, so as to provide insights into the sustainable development of schistosomiasis control in the context of the Chengdu⁃Chongqing economic circle construction.

摘要： 成渝地区双城经济圈以成都、重庆双城为中心，旨在打造中国经济“第四增长极”。虽然经济圈内四川省已有82.5%的流行县（市、区）达到血吸虫病消除标准、重庆市非血吸虫病历史流行区，但由于影响血吸虫病传播流行的自然、社会因素尚未根本消除，目前两地依然存在血吸虫病传播流行的风险。本文基于川渝两地血吸虫病流行现状，分析了成渝地区双城经济圈建设对血吸虫病防治工作带来的机遇与挑战，并提出有针对性的建议，以期为推动双城经济圈建设背景下血吸虫病防治工作的可持续发展提供参考。
