To analyze the results of echinococcosis surveillance in Yixing City from 2011 to 2018, so as to provide insights into echinococcosis control in the city.
All echinococcosis cases reported in Yixing City since 2007 that were captured from the China National Notifiable Infectious Disease Reporting Information System of Chinese Center for Disease Control and Prevention received a case study, and serological test and transabdominal B-mode ultrasound screening were performed among permanent residents and mutton market workers in Fangdong and Fangzhuang villages of Yixing City from 2011 to 2018. The cyst, mass and tubercle were detected in the liver and lung of the sheep from the mutton markets, and the coproantigen was detected in the canine stool samples from Fangdong and Fangzhuang villages. In addition, the awareness of echinococcosis prevention and control knowledge was investigated in the two villages using a questionnaire survey from 2011 to 2018.
A total of 7 cases with echinococcosis had been reported in Yixing City since 2007, with prevalence of 0.56/100 000, and all cases were -infected patients, including 2 cases with a history to travel to echinococcosis-endemic areas and 5 cases with a history of working in local mutton markets or dog contacts. From 2011 to 2018, a total of 1 861 residents received serological tests, with 0.54% seropositivity, and no seropositives were detected since 2016. Among the 1 807 individuals receiving transabdominal B-mode ultrasound screening, suspected cysts were found in 143 individuals (7.91%), and 1.40% (2/143) seropositivity was detected in these individuals. The mean positive rate of the coproantigen was 0.67% (3 /446) in the canine stool samples. Among the 4 010 sheep liver and lung specimens sampled from the mutton markets, 7 specimens (0.17%) were detected with cysts or tubercles. In addition, the mean awareness rate of echinococcosis prevention and control knowledge was 76.95% among the 538 subjects receiving questionnaire surveys from 2011 to 2018, and the overall awareness appeared a tendency towards a rise year after year.
Although the prevalence of echinococcosis and the seropositivity of anti- antibodies are low, there is still a risk of transmission of echinococcosis in Yixing City. The surveillance of echinococcosis should continue to be intensified and related control interventions are required.
分析2011年至2018年宜兴市棘球蚴病监测结果，为该市棘球蚴病防控提供依据。
对2007年以来宜兴市在中国疾病预防控制中心国家法定传染病报告信息系统中报告的所有棘球蚴病病例进行个案调查，并于2011年至2018年对宜兴市芳东和芳庄两村的常住人口及羊肉市场从业人员进行血清学检测和腹部B超筛查。检测羊肉市场羊的肝、肺中的包囊、肿物和结节，检测芳东和芳庄两村犬粪便样本中的粪抗原。此外，于2011年至2018年采用问卷调查的方式对两村居民的棘球蚴病防治知识知晓情况进行调查。
2007年以来宜兴市共报告棘球蚴病病例7例，患病率为0.56/10万，均为感染患者，其中有2例有疫区旅行史，5例有当地羊肉市场工作史或犬接触史。2011年至2018年，共1861名居民接受血清学检测，血清学阳性率为0.54%，2016年以来未检测到血清学阳性者。在1807名接受腹部B超筛查的人员中，143人（7.91%）发现疑似包块，其中血清学阳性率为1.40%（2/143）。犬粪便样本中粪抗原平均阳性率为0.67%（3/44此处原文有误，应为446/）。从羊肉市场采集的4010份羊肝肺标本中，7份（0.17%）检测到包囊或结节。此外，2011年至2018年接受问卷调查的538名对象中，棘球蚴病防治知识知晓率平均为76.95%，总体知晓率呈逐年上升趋势。
宜兴市棘球蚴病患病率及抗抗体血清学阳性率虽低，但仍存在棘球蚴病传播风险，应继续加强棘球蚴病监测并采取相关防控措施。
