Abstract: Objective To understand the characteristics of imported malaria cases in Qingcheng District， Qingyuan City and explore the strategies and priorities in prevention and control， so as to provide the evidence for improving the diagnosis， treatment and management of imported malaria. Methods The data of imported malaria as well as the case epidemiological investigations were collected and retrospectively analyzed for the species composition， original countries， population distribution， regional distribution， onset situation， diagnosis， treatment， etc. in Qingcheng District from 2011 to 2016. Results The number of imported malaria cases was 13 from 2011 to 2016. All the patients were confirmed by laboratory， and of which， 9 patients infected with Plasmodium falciparum， 1 with P. vivax， 1 with P. ovale and 2 with mixed infections （P. vivax and P. falciparum）. The yearly incidence of imported malaria presented an uptrend. The infection sources of all the patients were from African countries， and the exported labor workers and travelers for business from malaria endemic areas were the high risk population. The reported time was mainly January， February， November and December （11/13， 84.62%）. All the patients were male， and the majority of them （12/13， 2.31%） were 21-60 years old. The median time from onset to seeing a doctor was 2.5 days and the median time from seeing a doctor to being diagnosed was 1.9 day. Six patients （46.15%） were diagnosed as other diseases at the first visit to a doctor， and one patient died of falciparum malaria because of delayed diagnosis. Conclusions The incidence of overseas imported malaria presents an uptrend in Qingcheng District. It is necessary to further strengthen the professional training in medical staff to improve the diagnosis and treatment of malaria cases.

摘要： 目的 分析2011-2016年清远市清城区输人性疟疾病例特点并探讨防控对策，为进一步提高输入性疟疾诊治能力和管理水平提供参考依据。方法 回顾性分析2011-2016年该区所有输入性疟疾病例的个案调信息和流行病学资料，对境外输入性病例的虫种、来源、人群分布、地区分布、发病及诊治情况等进行描述性分析。结果 2011-2016年清城区报告输入性疟疾病例13例，其中恶性疟9例、间日疟1例、恶性疟间日疟混合感染2例、卵型疟再燃复发1例。年度输入性疟疾病例总数呈上升趋势，病例输入来源地均为非洲，报告时间主要在1-2、11、12月，占总病例数的84.62%（11/13），患者均为男性，以21 ~ 60岁为主，占病例总数的92.31%（12/13）；前往非洲疟疾流行区从事野外作业务工人员是输入性疟疾的高危人群。13例输入性疟疾病例均为实验室确诊，患者从发病到初次就诊时间中位数为2.5 d，最长为19 d；初诊到确诊时间中位数为1.9 d，最长为9 d；其中初诊诊断为其他疾病的有6例（46.15%），其中1例患者因延误诊治而死亡。结论 清城区境外输入性疟疾病例呈上升趋势，需加强多部门合作，建立高危人群建立监测、协查和健康干预等防控机制，确保输入性疟疾病人得到有效救治。
