目的分析福建省2003～2008年血吸虫病疫情监测情况,为制定今后防控策略提供依据。方法根据全国和福建省血吸虫病巩固监测方案,对全省16个血吸虫病流行县(市、区)2003～2008年监测数据进行统计,同时结合现场调查进行分析。结果钉螺面积由2003年的6.94 hm2增至2004年的50.67 hm2,2005～2006年经大力开展灭螺,增长态势得到遏制,至2008年,已压缩至5.77 hm2。开展血清学监测18 000人,其中流动人口5 412人,阳性110人,经粪检查出虫卵、毛蚴者8例,均为输入病例;共检查本省原疫区医院手术切除的阑尾标本7 885份,其中检出血吸虫虫卵者8例,经追查均为历史病人;有螺区共粪检耕牛2 709头,未发现感染血吸虫。结论本省残存钉螺面积依然存在,加上外来传染源不断输入,血吸虫病随时都有死灰复燃的危险。
Objective To analyze the epidemic situation of schistosomiasis in Fujian Province from 2003 to 2008 and provide basis for making future prevention and control strategies. Methods Based on the national and Fujian programs for the consolidation of schistosomiasis surveillance, the data of 16 counties (cities and districts) endemic to schistosomiasis in the province from 2003 to 2008 were collected and analyzed in combination with on-site investigation. Results The area of snails increased from 6.94 hm2 in 2003 to 50.67 hm2 in 2004. After the strong suppression of snails, the growth was suppressed to 5.77 hm2 by 2008. Serological surveillance of 18 000 people, of which 5 412 were floating population, positive 110 people, the fecal eggs were detected by feces, 8 cases of keratitis, were imported cases; a total inspection of the original plains in the province surgical resection of the appendix specimens 7 885 Among them, 8 cases were detected with Schistosoma japonicum eggs, which were both historic patients after tracing. There were 2,709 cattle in total fecal examination in the snail area, and no schistosomiasis was found. Conclusion The remaining snail area in our province still exists, and with the continuous input of external sources of infection, schistosomiasis is in danger of resurgence at any time.
