Abstract: Flood disasters frequently occur in schistosomiasis⁃endemic regions of China during the flood season, which causes a high risk of schistosomiasis transmission. Therefore, it is particularly crucial to control schistosomiasis transmission during the flood season. Based on field schistosomiasis control needs, this article proposes scientifical and operational countermeasures during three phases of pre⁃flood preparation, response to flood disasters, and post⁃flood management, and emphasizes multi⁃faceted interventions as responses to the risk of Oncomelania hupensis spread and schistosomiasis transmission caused by flood disasters, including information collection, risk assessment, material reserve, health education, Oncomelania hupensis control, cercariae elimination, personal protection, and preventive treatment, so as to provide insights into schistosomiasis prevention and control during the flood season.

Key words: Schistosomiasis, Flood season, Flood disaster, Transmission risk, Prevention and control

摘要： 我国血吸虫病流行区汛期洪灾多发，血吸虫病传播风险较高，在汛期开展血吸虫病防控尤为重要。本文基于血吸虫病现场防控需求，从汛期前准备、汛情应对和汛期后管理3个阶段提出科学可行的应对措施，强调通过资讯收集、风险研判、物资储备、健康教育、灭螺灭蚴、个人防护、预防性治疗等多个环节应对洪灾引发的钉螺扩散和血吸虫病传播风险，从而为汛期血吸虫病防控提供参考。
