Abstract: Objective　To analyze the epidemiological characteristics of imported malaria cases in Fujian Province from 2014 to 2018, so as to provide scientific basis for the development of the control strategy for imported malaria. Methods　The epidemiological data of malaria cases in Fujian Province from 2014 to 2018 were retrieved from the Notifiable Disease Reporting System and Parasitic Disease Information Reporting System of Chinese Center for Disease Control and Prevention, and the classification, origin of infections, temporal distribution, spatial distribution, population distribution, reporting institutions and diagnosis were analyzed. Results　A total of 540 overseas imported malaria cases were reported in Fujian Province from 2014 to 2018, and all cases were laboratory?confirmed, including 398 cases with falciparum malaria, 88 cases with vivax malaria, 38 cases with ovale malaria, 14 cases with malariae malaria and 2 cases with mixed infections. There were 90.56% (489/540) of the imported malaria cases with infections in 27 African countries, 5.92% (32/540) with infections in 5 Asian countries and 3.52% (19/540) with infections in one Oceania country. There was no significant seasonal distribution of the cases, and the imported malaria cases were predominantly detected in Fuzhou City (80.00%, 432/540) and at ages of 20 to 49 years (81.48%, 440/540). Initial diagnosis was predominantly at the city?level medical institutions, and 77.96% (421/540) were diagnosed as malaria at the initial diagnosis institutions. The median duration from onset to initial diagnosis was 2 days and 70.19% (379/540) were diagnosed within 3 days of onset. The interval between initial diagnosis and definitive diagnosis was 0 day, with 85.37% (461/540) definitively diagnosed within 3 days of initial diagnosis. Conclusions　Overseas imported malaria is a continuous problem challenging the malaria elimination programme of Fujian Province. Improving the healthcare?seeking awareness and the diagnostic capability of healthcare workers, and intensifying the monitoring and management of malaria among overseas labors are strongly recommended.

摘要： 目的　了解2014–2018年福建省输入性疟疾病例流行病学特征，为制定输入性疟疾防控策略提供科学依据。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和寄生虫病防治信息专报系统，收集2014–2018年福建省疟疾病例流行病学资料，对病例分型、感染来源、三间分布、报告单位和就诊情况进行分析。结果　2014–2018年福建省共报告境外输入性疟疾病例540例，均为实验室确诊病例，其中恶性疟398例、间日疟88例、卵形疟38例、三日疟14例、混合感染2例。感染来源包括非洲27个国家（90.56%，489/540）、亚洲5个国家（5.92%，32/540）和大洋洲1个国家（3.52%，19/540）；病例无明显季节分布特征，地区分布以福州市（80.00%，432/540）为主，年龄主要集中在20～49岁（81.48%，440/540）。病例首诊机构以地市级医疗机构为主，在首诊机构即被诊断为疟疾的病例占77.96%（421/540）；从发病到初诊时间间隔中位数为2 d，发病后3 d内就诊占70.19%（379/540）；从初诊到确诊时间间隔中位数为0 d，初诊后3 d内确诊占85.37%（461/540）。结论　福建省面临的境外输入性疟疾压力持续存在，应提高患者就诊意识与医务人员诊断能力，并加强对出国务工人群的监测和管理。
