To analyze the epidemic characteristics of the imported malaria cases in Guangxi Zhuang Autonomous Region in 2014, so as to assess the transmission risk and explore the prevention and control strategy.
The data of the malaria epidemic situation in the network direct report system of Guangxi in 2014 and the annual report of malaria epidemic situation in 14 cities were collected. The epidemiological information of the imported malaria cases was analyzed.
A total of 184 malaria patients were reported in Guangxi in 2014, with a descent rate of 85.29% when compared to that in 2013 (1 251 cases), and the incidence rate was 0.35/100 000. All the cases were imported from abroad, and four species of were found in their blood samples. The number of falciparum malaria cases was the most (49.46%), followed by the ovale malaria cases (32.07%). All the cases were distributed in 32 counties (districts) of 11 cities, and 65.76% of them were distributed in Shanglin County. Most of the cases were male (98.37%), and those aged in 20-49 years accounted for 87.50%. The imported cases came from 14 countries of Africa (86.41%) and 2 countries of Southeast Asia (13.59%), in which, 48.37% of the cases were imported from Garner. The main occupation of the cases in abroad was gold mining work (86.96%). The cases were reported all the year around, with no obvious seasonality. The interval time of back home to attack of the patients with tertian malaria and ovale malaria was longer.
Africa and Southeast Asia is the main source of imported malaria cases in Guangxi, and the migrant workers returning home may have the risk of malaria recurrence, which should be paid enough attention to.
分析2014年广西壮族自治区输入性疟疾病例的流行特征，评估传播风险，探索防控策略。
收集2014年广西网络直报系统疟疾疫情数据及14个市疟疾疫情年报，分析输入性疟疾病例的流行病学信息。
2014年广西共报告疟疾病例184例，较2013年（1251例）下降85.29%，发病率为0.35/10万。所有病例均为境外输入，血检发现4种疟原虫。恶性疟病例数最多（49.46%），其次为卵形疟病例（32.07%）。所有病例分布于11个市的32个县（区），65.76%分布在上林县。病例以男性为主（98.37%），20～49岁年龄组占87.50%。输入病例来自非洲14个国家（86.41%）和东南亚2个国家（13.59%），其中48.37%的病例来自加纳。病例在国外的主要职业为金矿开采工作（86.96%）。病例全年均有报告，无明显季节性。间日疟和卵形疟患者从回国到发病的间隔时间较长。
非洲和东南亚是广西输入性疟疾病例的主要来源地，返乡务工人员存在疟疾复发风险，应予以充分关注。
