目的 分析深圳市境外输入性疟疾病例特征,为其科学防治提供参考依据.方法 收集2007～2008年输入性疟疾病例资料,以描述流行病学的方法分析其特点;采用镜检法、Opti～MAL免疫层析法和PER三种检测方法核实诊断并进行虫株鉴定.结果 24例输入性病例,年龄介于21～55岁,男性23例,女性1例;其中3例为外国籍,其余为深圳外出从事商务回国人员;按输入来源地区:非洲21例,东南亚3例;输入病例主要集中在12月、1月和2月,合计13例,占总病例数的54%;镜检结果显示:16例为恶性疟,间日疟4例,未分型4例;以OptiMAL免疫层析法和PCR法核实鉴定,4例未分型者均为恶性疟,1例间日疟为恶性疟,1例间日疟为间日疟和恶性疟混合感染.结论 深圳境外输入性疟疾病例以深圳外出疟疾高发地区回国人员为主,且多为恶性疟;OptiMAL免疫层析法和PCR法对于疟疾病例的核实鉴定具有积极的辅助作用.“,”Objective To analyze the characteristics of imported malaria cases in Sbenzhen City from 2007-2008 . Methods The data of imported cases were collected and discriptively epidemiological mathod was used to analyze the infections and plasmodium in blood samples of the cases was detected and species identified by Opti-MAL, immunochromatography and PCR. Results The age of imported cases was from 21 to 55 years old,and 21 patiants were local residents,the others were foreigners. There 21 of the 24 imported cases,were imported from Africa and 3 from South-East Asia,and 54% of the cases mainly occurred in December,January and February.

Conclusion The imported malaria cases were mainly the returned local residents from hypeendemic areas outside China and most of them were falciparum malaria.The Opti-MAL and PCR tests were proved to be the alternative of the microscopy for identification of plasmodium species.
