摘要
目的分析四川省血吸虫病疫情反复风险因素,为巩固全省血防成绩和推进消除血吸虫病服务。方法收集2005-2015年四川省血吸虫病防治报表、监测点资料、中国疾控系统传染病报告网络,分析血吸虫病流行风险因素。结果2005-2015年四川省新发钉螺面积171.88万m^2,硬化沟渠和林园钉螺复现;四川省以外地区报到的四川籍血吸虫患者42例;2005-2015年全省报道急性血吸虫患者37例,2005年34例,2006年2例,2007年1例;湿地有残存钉螺,人工模拟钉螺漂浮扩散2 000 m^2以上,在无螺环境钉螺输入,1年的增殖倍数为51.24,部分湿地建设一定时间后出现钉螺。结论四川省新发钉螺出现,历史环境钉螺复现;流动人口传染源管理困难;湿地血吸虫病传播风险严重。建议全省建立血吸虫病预警机制,完善应急处置能力;加强血吸虫病疫情监测,开展可疑环境和毗邻环境的扩大查螺;建立血吸虫病监测点、哨点医院,加强血吸虫患者报告和首诊责任制;做好湿地血吸虫病监测,开展精准血防,区域整片规划,消除血吸虫病。
Objective To analyze risk factors for epidemic recurrence of schistosomiasis in Sichuan Province so as to consolidate the achievements of schistosomiasis control and propel elimination of schistosomiasis. Methods Annual reports of schistosomiasis control,data of surveillance points and data of the infectious disease reporting network of China CDC were collected and analyzed for risk factors for prevalence of schistosomiasis. Results Over the period from 2005 to 2015,1 718 800 m^2 of new areas with oncomelania snails had been discovered,and hardened ditch and field snails re-emerged; 42 patients from Sichuan Province were reported in other provinces. A total of 37 acute schistosomiasis cases were reported from 2005 to 2015,including 34 in 2005,3 in 2006 and 1 in 2007; there were remnant snails in wetlands. The area with simulated snail diffusion was over 2 000 m^2; with introduction of snails to a snail-free environment,the quantity increased by 51. 24 in one year.Snails appeared in some wetlands certain time after construction. Conclusion Emergence of snails in new areas and re-occurrence of snails in historical environments have been found in Sichuan Province; infection source management in floating populations is difficult; the risk of schistosomiasis transmission in wetlands is serious. It is suggested an early warning system against schistosomiasis be established to improve emergency response; surveillance of epidemic conditions be intensified through expanding survey of snails in potential habitants and adjoining habitants; surveillance sites and sentinel hospitals be established,and the system of patient reporting and firstvisit responsibilities should be strengthened; surveillance of schistosomiasis in wetlands,precision control and regional planning be implemented well.
