【摘要】 目的分析1996-2005年浙江省血吸虫病疫情监测情况,为制定防治对策提供科学依据。方法采用5m系统抽样结合环境抽查方法查螺,压碎法检查钉螺感染情况,以土埋为主结合药物的方法灭螺;血清学方法结合尼龙绢袋集卵孵化法对居民、流动人群及家畜进行查病,血清学阳性人(畜)用吡喹酮治疗。建立血吸虫病防治年报表,并进行数据汇总分析。结果10年全省累计查出有螺乡891个,有螺村2903个,螺点13273个,有螺面积711.18hm2,灭螺面积662.24hm2;累计解剖钉螺62.34万只,未查获阳性钉螺;累计血清学查病179.16万人,查出阳性者4.99万人,阳性率为2.79%。粪检3.52万人,未查出内源性血吸虫病人,但发现输入性血吸虫病人85例。耕牛查病6.70万头,均为阴性。结论浙江省血吸虫病疫情稳定,但流行条件仍然存在。今后要坚持查灭钉螺和防控传染源为主的综合性防治策略。更多还原

【Abstract】 To analyse the surveillance of schistosomiasis in Zhejiang province from 1996 to 2005, so as to provide the scientific strategy for schistosomiasis control, 5 meter-synchronously systematic samplings combined with the environmental Samplings were used for snail survey. The snails were dissected to determine the infection status and earth-covered method combined with drug treatment was used for snail elimination. Serological methods combined miracidium hatching method was used for examining residents, floating population and domestic animals. Positive cases were treated by praziquantel. Annual report forms were established for analysis. The results showed that the snails were found in 13 273 spot in 2 903 villages of 891 towns with area of 7 111 800 m2 in Zhejiang province from 1996 to 2005 and snails were eliminated in 6 622 400 m2 area. No infected snails were found among 623 400 living snails. There were 49 900 positive cases in 1 791 600 population which were examined by serological methods and the positive rate is 2.78%. 35 200 population were examined by feces examination and not autochthonic positive cases but 85 imported positive cases were found. No positive cases were found in 67 000 farm cattle. It is concluded that schistosomiasis status is stable in Zhejiang province, however, the prevalence factor for re-emerging of schistosomiasis is still in existence. Comprehensive strategy including emphasizing on snail and import source of schistosomiasis control will be persevered for the future.更多还原
