摘要: 目的  分析2002-2012年江西省血吸虫病流行动态及防治形势。  方法  采用现场调查、回顾性调查和资料复习相结合的方法,以村为单位对江西省2002-2012年血吸虫病的疫情动态和防治效果进行分析。  结果  2002-2012年,江西省传播阻断县由19个增至22个,传播控制县仍为8个,疫情控制县为9个。血吸虫病患者数由128 331例减少至73 102例;2002年人群血检和粪检阳性率分别为12.2%(99 708/818 704)和4.2%(862/20 443),2006年开始,人群血检和粪检阳性率逐年下降,至2012年分别降为5.2%(70 057/1 352 386)和0.4%(361/82 560)(P<0.01)。急性感染病例共624例,2005年后急性感染病例逐年下降,2012年降至3例(P<0.01)。2012年晚期血吸虫病患者数为7 779例,较2002年(5 463例)增加了42.4%。2012年耕牛粪检阳性率(1.3%,1 408/112 182)较2002年(4.7%,4 263/90 878)显著下降(P<0.01)。2005年的活螺密度和感染螺密度分别为1.441 1只/0.1 m2和0.003 6只/0.1 m2,之后均逐年下降,至2012年分别为0.083 5只/0.1 m2和0.000 037只/0.1 m2(均P<0.01);2012年的钉螺面积(80 988.99 ha)较2002年的(77 636.35 ha)增加了4.3%。2008年全省11个流行县达到疫情控制标准,通过考核验收。2002-2012年,血吸虫病防治力度不断增强,人群查病和化疗人数分别增加了65.2%和65.5%,耕牛查病和化疗分别增加了23.4%和251.1%,灭螺面积增加了617.8%,同时大范围推进了传染源控制的综合防治策略。  结论  2002-2012年,江西省血吸虫病各项疫情指标在2005年以后呈较快稳步的下降趋势,目前疫情已呈低度流行状态,人群和耕牛感染,以及钉螺等各项疫情指标均控制在较低水平。

Abstract: Objective  To analyze the status of prevalence and control of schistosomiasis in Jiangxi Province from 2002 to 2012.  Methods  Endemic status and control effectiveness during the period from 2002 to 2012 was analyzed by using a combination of field survey, data collection and retrospective investigation.  Results  From 2002 to 2012, schistosomiasis control made significant achievements in Jiangxi Province. The number of counties which have reached the criteria of transmission interruption of schistosomiasis increased from 19 in 2002 to 22 in 2012. The number of patients with schistosome infection decreased from 128 331 in 2002 to 73 102 in 2012. The positive rate of serological test and fecal examination in residents decreased from 12.2% and 4.2% in 2002 to 5.2% and 0.4% in 2012, respectively. Acute infection reduced from 146 cases in 2002 to 3 cases in 2012, but advanced cases increased by 42.4%. The positive rate of fecal examination in cattle reduced from 4.7% in 2002 to 1.3% in 2012. The density of living snails and infected snails significantly decreased to 0.083 5/0.1 m2 and 0.000 037/0.1 m2 in 2012, respectively. However, the snail-ridden areas slightly increased. Jiangxi Province reached the criteria of endemic control for schistosomiasis in 2008. During 2002-2012, control activities were intensified. Examination and chemotherapy for human increased by 65.2% and 65.5%, while 23.4% and 251.1% for cattle. Mean while, area with snail control activities increased by 617.8%. An integrated strategy of infection source control was implememted in the Province.  Conclusion  During 2002 to 2012, endemic index of schistosomiasis in Jiangxi showed a steady decline after 2005. Currently, schistosomiasis prevalence shows a low level. The endemic indicators of infection in human and livestock as well as Oncomelania snails have been kept stable at low level.
