目的了解血吸虫病潜在流行区血吸虫病的潜在流行危险因素,做好血吸虫病潜在流行区的监测预警,为防治工作提供科学依据。方法2008年和2012年对固定监测点人群、2008-2012年对流动监测点人群,采取血清学和病原学方法检测血吸虫感染情况。每年对固定监测点进行螺情调查,在水体钉螺监测点采用网捞法和稻草帘诱螺法进行钉螺扩散监测。结果检测当地居民2 568人,IHA检测抗体阳性7人,阳性率为0.27%,粪检未发现阳性者;检测渔船民1 275人,IHA检测抗体阳性19人,阳性率为1.49%,粪检18人,阳性1人。查螺面积859.73 hm2,发现有螺条块3个,有螺面积24.55 hm2,其中新发现有螺条块2个,有螺面积20.23 hm2;打捞漂浮物530 kg,投放稻草帘80块,结果均未发现钉螺。结论发现了输入性传染源和新的螺区。加强对渔船民等流动人口的监测与管理、加强螺情监测和防止钉螺扩散是今后金湖县血吸虫病潜在流行区防控工作的重点。关键词:血吸虫病;潜在流行区;监测
Objective To understand the potential epidemic risk factors of schistosomiasis in endemic areas of schistosomiasis and to monitor and alert the potential epidemic areas of schistosomiasis so as to provide a scientific basis for prevention and treatment. Methods 2008 and 2012, the population of fixed monitoring point, 2008-2012, mobile monitoring point population, serological and pathogenic methods to detect schistosomiasis. An annual survey of fixed monitoring points for snails, snail fishing sites in the water snail method and the straw curtain lure method Snail proliferation monitoring. Results A total of 2 568 local residents were tested, including 7 positive IHA test patients and 0.27% positive testosterone. No negative test was found in stool samples; 1 275 were detected in fishing boat, 19 were positive for IHA test antibody, the positive rate was 1.49% 18 people, one positive. Snail area 859.73 hm2, found a screw block 3, a spiral area of 24.55 hm2, of which newly found a screw block 2, with a spiral area of 20.23 hm2; floating float 530 kg, put straw curtain 80, the results were Snail not found. Conclusion The sources of imported infectious agents and new spirochetes were found. To strengthen the monitoring and management of floating population such as fishing boat people and strengthen the monitoring of snail and prevent the spread of snail is the focus of prevention and control of potential epidemic area of schistosomiasis in Jinhu County in the future.
