Objective: To understand the reporting situation of schistosomiasis cases in National Notifiable Disease Report System (NNDRS) in China from 2015 to 2017, and to seek current deficiencies on case reporting as well as to analyze the epidemiological characteristics of schistosomiasis cases.
Methods: The data of schistosomiasis cases in China from 2015 to 2017 were collected from NNDRS, and the reporting situation and epidemiological characteristics of schistosomiasis cases were analyzed.
Results: From 2015 to 2017, totally 59 981 schistosomiasis cases were reported in China, among which, 1 460 cases were deleted, and 58 521 were censored cases. The statistics and analysis showed that a part of the case reporting had been carried out in nonstandard ways, mainly involving the random deletion of cases, reporting time not compliance with regulations, incorrect classification, and severe omission of cases. Among the 58 521 censored cases, the sex ratio of the male to the female was 1.83∶1, the average age of the cases was (51.91 ± 11.30) years, and farmers and fishermen accounted for 93.26% (54 577 cases) and 3.46% (2 022 cases), respectively. The reported cases mainly concentrated in Anhui, Hunan, Hubei and Jiangxi provinces, accounting for 99.73% of the total number in China. During this period, Beijing, Zhejiang and other provinces (cities and regions) reported 11 imported schistosomiasis cases, all of them were schistosomiasis mansoni cases or schistosomiasis haematobia cases.
Conclusions: From 2015 to 2017, the reported cases of schistosomiasis are mainly clinically diagnosed cases. Compared with the annual report of the national schistosomiasis control, the number of confirmed cases in NNDRS is seriously missed. Therefore, the endemic provinces should strengthen the supervision on confirmed cases and reporting quality of schistosomiasis cases in accordance with the relevant law and regulation.
[摘要] 目的 了解全国传染病网络直报系统中血吸虫病病例报告情况, 查找病例报告工作中存在的不足, 并对报告病 例流行特征进行分析。方法 在全国传染病网络直报系统中, 导出 2015–2017 年血吸虫病报告病例数据, 分析病例上报 情况及病例流行病学特征。结果 2015–2017 年全国传染病网络直报系统共上报血吸虫病病例 59 981 例, 其中删除病例 1 460 例、终审病例 58 521 例。病例报告中存在不规范问题, 主要涉及随意删除病例、病例上报时间不符合规定、病例 分类错误和漏报。58 521 例终审病例中, 男女性别比为 1.83∶1; 平均年龄 (51.91 ± 11.30) 岁, 农民和渔 (船) 民分别占 93.26% (54 577 例) 和 3.46% (2 022 例) 。国内病例主要集中在安徽、湖南、湖北和江西, 4 省报告病例数占全国病例总数 的 99.73%。北京、浙江等省 (直辖市、自治区) 共报告 11 例国外输入性曼氏血吸虫病和埃及血吸虫病病例。结论 2015–2017 年全国传染病网络直报系统中血吸虫病报告病例以临床诊断病例为主; 与全国血吸虫病防治工作年报表相比, 全 国传染病网络直报系统中血吸虫病确诊病例漏报严重。.
