广西柳州市199例输入性疟疾病例流行病学分析

目的分析广西柳州市在消灭疟疾后，输入性病例的发病特点和流行特征，为巩固疟疾防治成果和制定监测对策提供科学依据。方法收集1982-2007年所有输入性病例199例的临床及流行病学调查资料进行分析。结果外出回归人员比外来流动人员发病率高；外来人员及本地外出返回的流动人口为主要发病人群；间日疟为主要虫种；每年的5-11月为发病高峰；病例以男性青壮年为主；疟疾高流行地区返回和外来的流动人口及非洲援外回国人员是主要患病人群。结论制定消灭疟疾后的监测策略和计划时，要充分考虑输入性病例的流行特点，加强流动人口，特别是来自高疟疾流行区人群的管理与监测。

An epidemic analysis on 190 imported malaria cases in Liuzhou,Guangxi

Objective To analyze the incidence and epidemic characteristics of imported malaria cases after malaria were eliminated in Liuzhou city, provide scientific basis for consolidating the results of malaria control and prevention, and formulating the strategies of malaria surveillance. Methods The study was carried out on all the date of clinic and epidemiology collected from the imported malaria cases after malaria was eliminated. Results The major population suffering from malaria was the floating population, especially those from the areas with high incidence rate, including Africa, with the incidence being higher in the population back from overseas than in the floating population from other domestic areas. The plasmodium vivax was found to be the most common of malaria species. The malaria incidence peaked from May to November each year, majority of which was male young adults. Conclusion Considering the epidemic characteristics of imported cases, we should reinforce the management and surveillance of floating population, especially those who were from the areas with high malaria incidence rate, when establishing the surveillance strategies and plans for malaria control after it was eliminated locally.
