2008-2012年溧阳市棘球蚴病监测

Surveillance of echinococcosis in Liyang City from 2008 to 2012

目的了解溧阳市人畜棘球蚴或棘球绦虫感染情况，为制定棘球蚴病防控措施提供科学依据。方法对确诊病例和线索病例进行个案调查。采用ELISA法检测重点地区和对照地区7～12岁儿童、成人血清特异抗体，对血清学检查阳性者及其家属和邻居作B超检查；采用ELISA法检测重点地区犬粪棘球绦虫抗原；对羊肉屠宰交易市场羊只内脏进行剖检。结果儿童、成人血清抗体阳性率分别为0．93％和0．52％，两者差异无统计学意义（i。2．124，P〉0．05）。B超检查未发现阳性病人。羊只内脏剖检未发现棘球蚴感染情况，犬粪阳性率为0．95％。结论溧阳市棘球蚴病监测中检出人群血清抗体阳性者和粪便抗原阳性犬，且该市存在完整传播链。因此，在棘球蚴病防控工作中，应加强对重点地区犬粪监测、外来羊只检疫以及人群健康教育。

Objective To investigate the Echinococcus infection of people and domestic animals in Liyang City, so as to pro- vide the evidence for the establishment of control measures of echinococcosis. Methods The formerly confirmed cases and clue cases were investigated. The Echinococcus antibody in serum of children aged from 7 to 12 years old and adults in key towns and control towns was detected with ELISA, and the antigen in fecal samples of dogs in key towns was also detected. B ultrasound was applied to examine the ELISA positive cases, family member and the neighbored people around them. The sheep in the market were dissected and examined for Echinococcus. Results The Echinococcus antibody positive rates were 0.93% and 0.52% in chil- dren and adults, respectively. The Echinococcus antigen positive rate was 0.95% in dogs. There were no significant difference be- tween the positive rates of the children and adults （ Z2 = 2.124, P 〉 0.05）. No cases were found by ultrasonic examination and no Echinococcus infection was found in the sheep. Conclusion The people with Echinococcus antibody in serum and dogs with anti- gen in their feces are found in the surveillance of echinococcosis, therefore, there exists the complete chain of transmission in lo- cal. Thus, in the prevention and control work for the disease, the monitoring of dog feces, quarantine of sheep from other regions, as well as the population health education in key areas should be strengthened.
