2003～2008年福建省血吸虫病疫情分析

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 hm^2增至2004年的50.67 hm^2,2005～2006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 hm^2。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。

Schistosomiasis endemic situation in Fujian Province from 2003 to 2008

In order to understand the situation of schistosomiasis in Fujian Province, the surveillance and field survey data of 16 counties (cities or districts) were statistically analyzed from 2003 to 2008 according to the national and provincial surveillance protocols. The snail areas were 69 400 m~2 in 2003, and 506 700 m~2 in 2004, then decreased to 57 700 m~2 in 2008 after the snail control in 2005 and 2006. Serological examinations were conducted in 18 000 people, among which 5 412 people were the mobile population from schistosome-endemic areas, and 110 persons were positive, among which 8 persons had eggs and miracidia in their stools, among 7 885 appendix samples, Schistosoma japonicum eggs were found in 8 samples of the patients who came from the o-riginal endemic areas. By the stool examination, 2 709 head of farm cattle in the region with snails were not found infected with Schistosoma japonicum. It is suggested that the areas of residual snails are large and widespread, and the imported patients are found frequently, so the danger of schistosomisis transmission still remains.
