【摘要】：目的分析重庆市2015年输入性疟疾病例实验室诊断结果及流行病学特征。方法按照《重庆市疟疾诊断参比实验室工作手册》操作规程,采用涂片镜检、快速疟疾诊断试纸条(RDT)及巢式PCR对该市输入性病例进行实验室诊断分型,并从寄生虫病防治信息管理系统收集疟疾个案调查资料进行分析。结果 2015年重庆市共报告境外输入性疟疾病例31例,其中间日疟2例(6.45%)、恶性疟23例(74.19%)、卵形疟5例(16.13%)、三日疟1例(3.22%),5例卵形疟中3例经实验室诊断为卵形疟wallikeri亚型。30例(96.77%)输入自非洲,1例(3.33%)输入自东南亚;30例为男性,1例为女性,年龄23~61岁,病例分布无明显季节性。病例从发病到初次就诊时间、从初次就诊到确诊时间的中位数均为2 d,初次就诊单位多为县级单位,确诊单位多为省级单位。结论重庆市2015年疟疾病例均为输入性,未发现本地病例,仍保持消除疟疾状态,但仍要加强输入性疟疾病例的管理及病原学监测工作,并加强相关疟疾防治机构医务人员的防治能力培训。
[Abstract]:Objective to analyze the laboratory diagnosis and epidemiological characteristics of imported malaria cases in Chongqing in 2015. Methods according to the operating rules of Chongqing reference Laboratory for Malaria diagnosis, smear microscopic examination, rapid malaria diagnosis test strip (RDT) and nested PCR were used for laboratory diagnosis and typing of imported cases in this city. The data of malaria case investigation were collected from the information management system of parasitosis prevention and control. Results in 2015, 31 imported malaria cases were reported in Chongqing. Among them, 2 cases (6.45%) of vivax malaria, 23 cases of falciparum malaria (74.19%), 5 cases of oval malaria (16.13%), 1 case of 3-day malaria (3.22%) and 5 cases of ovoid malaria, 3 cases (96.77%) were imported from Africa, 1 case (3.33%) were imported from Africa, 30 cases were male and 1 case was female. The age was 23 ~ 61 years old and the distribution of the cases was not seasonal. From the onset to the first visit, the median time from the first visit to the diagnosis was 2 days, the first visit was mostly county-level units, and most of the diagnostic units were provincial units. Conclusion all malaria cases in Chongqing in 2015 were imported, no local cases were found, and the status of malaria elimination was maintained. However, the management of imported malaria cases and etiological surveillance should be strengthened. And strengthen the training of medical staff of malaria control institutions.
