Surveillance is an important part of the national schistosomiasis control program of China, which play a critical role in facilitating the progress towards elimination of schistosomiasis in China. The coverage of schistosomiasis surveillance has shifted from the high-risk regions at the initial stage of the national schistosomiasis control program of China to the current all endemic counties (cities, districts), and the surveillance contents have extended from single surveillance of endemic status to comprehensive surveillance of endemic status, epidemic factors and transmission risks. With the continuous progress towards schistosomiasis elimination, the national schistosomiasis control program has shifted from "extensive control" to surveillance and early warning-based "precision control" in China, which proposes much higher requirements for schistosomiasis surveillance. Currently, the surveillance of schistosomiasis has been covered in all schistosomiasis-endemic counties (cities, districts) of China, and the development of rapid and early identification of cercariae and -infected snails will greatly improve the sensitivity of and the duration of responses to schistosomiasis surveillance, which will provide powerful tools for elimination of schistosomiasis in China.
监测是中国国家血吸虫病防治计划的重要组成部分，对推动中国血吸虫病消除进程发挥着关键作用。血吸虫病监测的覆盖范围已从中国国家血吸虫病防治计划初期的高危地区扩大到目前的所有流行县（市、区），监测内容也从单纯的疫情监测扩展到疫情、流行因素和传播风险的综合监测。随着血吸虫病消除工作的不断推进，中国国家血吸虫病防治计划已从“粗放式防治”转向基于监测和预警的“精准防治”，这对血吸虫病监测提出了更高要求。目前，中国所有血吸虫病流行县（市、区）均已开展血吸虫病监测，快速早期识别尾蚴和感染性钉螺将大大提高血吸虫病监测的敏感性和反应时效，为中国消除血吸虫病提供有力工具。
