摘要:

目的 了解上海市2010-2017年疟疾流行特征,为及时调整上海市消除疟疾进程中的策略和措施提供依据。方法 收集中国疾病预防控制中心传染病报告信息管理系统中2010-2017年上海市疟疾病例的流行病学个案信息,采用Microsoft Excel 2010软件对疟疾病例的诊断分型、诊断时间、感染来源和流行特征等进行统计分析。结果 2010-2017年上海市共报告疟疾病例359例,死亡3例。报告病例中,临床诊断病例10例(2.8%),实验室确诊病例349例(97.2%),其中恶性疟241例(67.1%)、间日疟60例(16.7%)、卵形疟26例(7.2%)、三日疟13例(3.6%),未分型9例(2.5%)。自2010年起,上海市无本地感染疟疾病例报告。病例诊断时间间隔的中位数为4.4 d,发病后3 d内确诊的病例占48.2% (173/359)。病例报告无明显季节分布。病例以男性中青年为主,包括在沪户籍105例(29.2%),外省户籍207例(57.7%),外籍47例(13.1%)。现居住地分布于全国19个省(市、区)的92个区(县),其中上海市居住地病例占72.7%(261/359),分布于全市16个区。报告病例中除1例输血感染的三日疟和1例感染地不明的三日疟外,其余均为输入性病例,其中境外输入病例占94.2%(338/359),国内外省输入病例占5.3%(19/359)。自2012年起,上海市报告的输入性疟疾病例的感染来源地均为境外。结论 上海市自2010年起无本地感染疟疾报告,仍有境外感染疟疾病例输入和死亡病例发生。

Abstract:

Objective To understand the epidemiological characteristics of malaria cases reported in Shanghai from 2010 to 2017, so as to provide evidence-based reference for adjusting strategies and measures in the process of malaria elimination in Shanghai. Methods The epidemiological data of malaria cases reported in Shanghai from 2010 to 2017 were collected. Classification, diagnosis time, infection source and epidemiological characteristics of the cases, were statistically analyzed by using Microsoft Excel 2010. Results A total of 359 malaria cases were reported in Shanghai from 2010 to 2017 with 3 deaths. Among them 10 patients were clinically diagnosed (2.8%, 10/359) and the rest were laboratory diagnosed (97.2%, 349/359). 241 were infected with P. falciparum (67.1%, 241/359), 60 with P. vivax (16.7%, 60/359), 26 with P. ovale (7.2%, 26/359), 13 with P. malariae (3.6%, 13/359) and 9 infected with unknown species (2.5%, 9/359). All cases were imported and there was no indigenous case reported in Shanghai since 2010. The median diagnosis time was 4.4 days after the clinical symptoms occurred, 47.8% (137/359) cases were diagnosed within 3 days. There was no significantly seasonal difference in the case report. Young and middle-aged men were preferably infected. The case distribution included 105 Shanghai native residents (29.2%, 105/359), 207 from other provinces (57.7%, 207/359) and 47 foreigners (13.1%, 47/359). The current living address of cases distributed in 92 counties in 19 provinces of China, and 261 cases (72.70%, 261/359) were Shanghai residents distributed in 16 districts of Shanghai. 338 cases (94.2%, 338/359) were imported from overseas, and 19 cases (5.3%, 19/359) were imported from other provinces of China. Since 2012 all reported cases were imported from overseas except for one case of P. malariae transmitted by blood transfusion and one case of P. malariae without definite source of infection. Conclusion No indigenous malaria case has been reported in Shanghai since 2010. However, there are still imported malaria cases mainly from overseas so that we need to pay attention to malaria surveillance in Shanghai.
