摘要： 目的 分析广西壮族自治区国家级血吸虫病监测点监测数据，评估防控成效，为优化区域防控策略提供依据。方法 依据《全国血吸虫病监测方案（2020年版）》，2020—2024年在广西20个历史血吸虫病流行县（市、区）设立国家级监测点，开展流动人群和家畜血吸虫病感染状况以及钉螺分布与感染情况监测，对监测结果进行描述性分析。结果 累计监测流动人群20 473人·次，仅2020年检出1例血清学阳性，未发现粪检阳性。累计监测家畜5 794头·次，均未检出粪检阳性。累计开展钉螺调查3 164.89 hm2，有螺面积从57 971 m2逐年降至29 810 m2；累计发现复现有螺面积1 926 m2，未发现感染性钉螺。除2020年外，其余年份有螺环境均以沟渠为主；沟渠环境的有螺框出现率总体呈上升趋势（χ2趋势=726.425，P<0.001），水田和其他类型环境则呈下降趋势（χ2趋势=17.392、127.940，P均<0.001）。结论 广西继续维持血吸虫病消除状态，无本地和输入性病例，但血吸虫病传播的风险依然存在。今后应进一步做好血吸虫病监测工作，持续巩固消除成果。

Abstract: Objective To analyze the surveillance data from national schistosomiasis monitoring sites in Guangxi Zhuang Autonomous Region, and evaluate the effectiveness of prevention and control measures for providing a basis to optimize regional prevention and control strategies. Methods Between 2020 and 2024, national-level surveillance sites were established in the counties (cities, districts) where schistosomiasis was endemic in history in Guangxi Zhuang Autonomous Region in compliance with the National Schistosomiasis Surveillance Program (2020 Edition), an conducted surveillance on the schistosomiasis infection status in floating populations and livestock, as well as the distribution and infection status of Oncomelania hupensis. Then the surveillance results were analyzed by descriptive method. Results A total of 20 473 person-times floating subjects were monitored, in whom only one person was found to be serologically positive in 2020. No fecal test-positive cases were identified. Surveillance over 5 794 head-times of livestock revealed no fecal test-positive specimens. Snail survey was conducted on a total of 3 164.89 hm2 areas, which suggested that the snail-infested area was decreased annually from 57 971 m2 to 29 810 m2. A cumulative re-emerged snail-infested area of 1 926 m2 was identified, yet no infected snails were found. Except for 2020, snail-infested environments in other years were predominantly associated with ditches. The frame positivity rate of snails in ditches showed an overall increasing trend (χ2trend=726.425, P<0.001), whereas that in paddy fields and other environments showed a decreasing trend (χ2trend=17.392 and 127.940, both P<0.001). Conclusion Guangxi Zhuang Autonomous Region continues to maintain the schistosomiasis elimination status, and absence of local or imported cases. However, the risk of schistosomiasis transmission still exists. In the future, further efforts should be made to improve schistosomiasis monitoring and continuously consolidate the achieved elimination outcomes.
