摘　　要：目的分析2012—2013年广西境外输入性疟疾病例感染来源地区、感染疟原虫种类,病例人群、地区和季节分布,诊治报告情况,为控制输入性疟疾传播提供依据。方法收集2012—2013年全自治区各县（市、区）疟疾年度报表、人口资料和疟疾病例个案调查资料进行统计分析。结果 2012—2013年广西共报告输入性疟疾1 470例,其中恶性疟占输入性疟疾病例总数86.87%（1 277例）、间日疟占9.32%（137例）、三日疟占0.88%（13例）、卵形疟占1.43%（21例）、混合感染占1.16%（17例）和临床诊断疟疾占0.34%（5例）。男性病例占病例总数98.78%（1 452例）,女性占1.22%（18例）,21-50岁病例占病例总数92.25%（1 356例）;来自非洲的病例占病例总数95.03%（1 397例）,来自东南亚的病例占4.97%（73例）;农民工病例占病例总数91.70%（1 348例）,输入疟疾病例分布于13个地级市54个县（市、区）。疟疾患者返乡后1d内确诊并接受治疗的病例占病例总数46.60%（685例）,2d内者占68.02%（1 000例）,3-4d者占16.46%（242例）,5d-者占15.51%（228例）。输入疟疾病例数增加,致使2012年全自治区疟疾发病率（0.42/10万）比2011年（0.22/10万）上升90.91%,2013年发病率（2.37/10万）比2012年上升464.29%。但由于措施得当,输入疟疾未在当地引起传播。结论加强农民工健康教育和医疗卫生人员疟疾诊治知识培训,早期发现、治疗传染源是控制输入性疟疾传播和减少疟疾病例死亡的重要措施。Objective To analyze the effects of the prevalence of imported malaria in Guangxi from 2012 to 2013,areas where cases originated,plasmodium species involved,affected populations,regional and seasonal distribution,and diagnosis and treatment reports in order to provide a basis for controlling the spread of imported malaria. Methods Annual reports of malaria from 2012 to 2013and demographic data from each county in Guangxi（cities and regions）were collected along with case reports,and this collected information was analyzed. Results From 2012 to 2013,there were 1 470 cases of imported malaria reported.Malaria was caused by Plasmodium falciparumin 86.87% of these cases（1 277/1 470）,by P.vivaxin 9.32%（137/1470）,by P.malariain 0.88%（13/1470）,and by P.ovale in 1.43%（21/1470）.A mixed infected was noted in 1.16% of cases（17/1 470）and malaria was clinically diagnosed in 0.34%（5/1470）.Individuals ages 21-50 accounted for 92.25% of patients with malaria（1 356/1 470）.Males accounted for98.78% of patients（1 452/1 470）while females accounted for 1.22%（18/1 470）.Malaria originated from Africa in95.03%of cases（1 397/1 470）and from Southeast Asia in 4.97%（73/1 470）.Migrant workers accounted for 91.70%of patients（1 348/1 470）.Cases of imported malaria were distributed throughout 13 cities and 50counties（cities and regions）.In 46.60% of cases（685patients）,malaria was definitively diagnosed and treated within a day of the patient＇s return home.In 68.02% of cases（1 000patients）,malaria was definitively diagnosed and treated within two days.In16.46%of cases（242patients）,malaria was definitively diagnosed and treated in 3-4days.In 15.51% of cases（228patients）,malaria was definitively diagnosed and treated after 5days after the patient returned home.Cases of imported malaria increased,causing the morbidity rate in 2012（0.42/100 000）to increase 90.91% compared to the rate in 2011（0.22/100 000）throughout Guangxi.The morbidity rate in 2013（2.37/100 000）was
