Abstract: Objective　To analyze the epidemiological characteristics of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2011, so as to provide insights into for echinococcosis control and surveillance. Methods　The data pertaining to reported echinococcosis cases in Henan Province from 2010 to 2021 were retrieved from the National Notifiable Disease Report System, and a descriptive epidemiological analysis was performed using the software SPSS 22.0. Results　A total of 150 echinococcosis cases were reported in Henan Province from 2010 to 2021, including 88 confirmed cases (58.67%) and 62 clinically diagnosed cases (41.33%), 77 cases reported by Henan Province (51.33%) and 73 cases reported by other provinces (48.67%). Echinococcosis cases were reported in each month, with 8 to 21 cases reported in each month, and the number of reported echinococcosis cases appeared no remarkable temporal changes. The echinococcosis cases were reported across 18 cities of Henan Province, with the highest number of cases reported in Zhoukou (17.33%) and Nanyang cities (17.33%) and the lowest number reported in Sanmenxia City (0.67%). The reported echinococcosis cases had a male to female ratio of 1.17∶1, and the cases were found at each age group, with the the highest number of cases seen at ages of 20 to 59 years (73.33%). Farmer was the predominant occupation (63.33%), followed by housekeepers and the unemployed (12.67%). Of all reported echinococcosis cases, there were 25 local cases (16.67%) and 125 imported cases (83.33%), 144 cases reported by medical institutions (96.00%) and 6 cases reported by centers for disease control and prevention (4.00%). Conclusions　Although imported echinococcosis cases were the predominant source of echinococcosis cases reported in the National Notifiable Disease Report System in Henan Province from 2010 to 2021, there were still sporadic local cases, and the emergence of local sources of infection cannot be excluded. Further expanded field surveys and surveillance of echinococcosis are required.

摘要： 目的　了解2010—2021年河南省棘球蚴病网络报告病例流行病学特征，为制定棘球蚴病防治与监测措施提供参考依据。方法　通过中国疾病预防控制中心传染病报告信息管理系统，收集2010—2021年河南省棘球蚴病网络报告病例信息，对病例流行病学特征进行描述性统计分析。结果　2010—2021年河南省累计报告棘球蚴病病例150例，其中确诊病例占58.67%、临床诊断病例占41.33%，河南省上报病例占51.33%、外省上报病例占48.67%。各月份均有棘球蚴病病例报告，病例数量变化无明显时间规律，各月发病数8 ~ 21例；棘球蚴病病例分布于全省18个市，其中周口市和南阳市病例数最多（占17.33%），三门峡市病例数最少（占0.67%）；病例性别比为1.17∶1，分布于各年龄组，以 20 ~ 59岁年龄组占比最高（占73.33%）；病例职业以农民为主（占63.33%），其次为家务及待业人员（占12.67%）。所有棘球蚴病病例中，本地病例占16.67%，输入性病例占83.33%；由医疗机构上报病例占96.00%，由疾病预防控制机构上报占4.00%。结论　2010—2021年河南省棘球蚴病报告病例以输入性病例为主，仍有零星本地报告病例，不排除存在当地传染源的可能性；需进一步扩大现场调查，并开展棘球蚴病监测。
