江门市蓬江区华支睾吸虫病防治试点效果观察

2008年6月～12月在江门市蓬江区华支睾吸虫病综合防治示范区随机抽取5个村,每个村检查500人左右。采用改良加藤厚涂片法(一送三检)检测华支睾吸虫感染率,同时对感染者进行驱虫治疗。治疗后1个月,每个村再随机选取50人,粪检华支睾吸虫卵。治疗后1年,从大林村和三丫村治疗者中再次随机各选取50人,粪检虫卵。在开展宣传教育前后,问卷调查华支睾吸虫病防治知识知晓率,调查无害化卫生户厕普及和使用情况。结果 5个村华支睾吸虫平均感染率为21.5%(537/2 501),感染者自愿治疗率为86.6%(465/537)。治疗后1个月,除富岗村外,其他4个村华支睾吸虫感染率明显下降(P<0.05)。治疗后1年,大林和三丫村华支睾吸虫阳性率与治疗后1个月相近(P>0.05)。问卷调查分析结果显示,华支睾吸虫感染者经常食鱼生者占41.2%(170/413),明显高于未感染者4.2%(8/192)(P<0.05);开展防治知识宣传后,村民华支睾吸虫病防治知识知晓率从23.1%(135/584)上升到84.5%(349/413)(P<0.05)。卫生户厕普及率93.2%(38 068/40 848),使用率100%。

Pilot Observation on the Effect of Integrated Control Measures against Clonorchiasis in Pengjiang District of Jiangmen City

From June to December in 2008,five villages were randomly chosen from Pengjiang District of Jiangmen city and about five hundred residents from each village were examined for clonorchiasis by Kato-Katz method(three slides per specimen).Fifty residents from each village were re-examined one month after treatment.One year later 50 treated residents were chosen from Dalin village and Sanya village for fecal examination.Questionnairing was conducted to determine the knowledge rate on clonorchiasis prevention among residents.The percentage and usage of sanitary toilets were investigated.The average infection rate of clonorchiasis from five villages was 21.5%(537/2501).86.6%(465/537)of clonorchiasis received treatment voluntarily.One month after treatment the infection rate in four villages declined significantly.The positive rate showed no significant difference between one month and one year after treatment in Dalin and Sanya villages(P>0.05).Questionairing indicated that 41.2%(170/413)of the clonorchiasis cases ate raw fish frequently,which was significantly higher than those non-infected people[4.2%,8/192](P<0.05).After health education,the knowledge awareness rate raised from 23.1%(135/584)to 84.5%(349/413)(P<0.05).The dissemination and usage of sanitary toilets were 93.2%(38 068/40 848)and 100%,respectively.
