Abstract: Objective To understand the geographical features of malaria in Yunnan Province, so as to provide the reference for malaria elimination. Methods The data of malaria in Yunnan Province from 2012 to 2015 were collected and analyzed. Results Totally 2 586 malaria cases were reported in Yunnan Province from 2012 to 2015, in which 274 (10.60%) were local cases and 2 311 (89.37%) were abroad imported, and one (0.03%) was domestic imported. The imported malaria cases and local cases were analyzed according to the sources and locations respectively, and the arithmetic means of the numbers of imported and local cases were 96.29 and 10.96 respectively, the standard deviations of the numbers of imported and local cases were 421.18 and 19.12 respectively, and the difference of the means was not significant (Z = - 0.326, P > 0.10). Both the imported and local malaria cases could be clustered into five sections by the number of 5. The Herfendal?Hirshman indexes of the imported and local malaria cases were 8 121 and 1 598 respectively. Conclusions There is no significant difference of the distribution between the imported and local malaria cases, and they should be attaching equal importance. The non?uniform degree of imported cases is higher than that of the local cases, while both of them could be divided into five major clusters in the prevention and control work.

摘要: 目的 了解云南省疟疾病例的地理分布特征,为疟疾消除工作提供借鉴。 方法 收集2012-2015年云南省疟疾病例资料,建立数据库并分析病例聚集情况。 结果 2012-2015年云南省共计报告疟疾病例2 586例,其中本地感染274例,占10.60%,境外输入2 311例,占89.37%,外省输入1例,占0.03%;按照来源地与病例所在地分别统计境外输入病例数与本地病例数,算术均数分别为96.29和10.96,标准差分别为421.18和19.12,均数差异无统计学意义(Z = - 0.326,P > 0.10)。境外输入区域与本地感染区域的聚集性均可以群集数5来初分,均具备地理聚集的特点。境外输入病例与本地病例的赫尔芬达尔?赫希曼指数分别为8 121和1 598。 结论 云南省境外感染病例与本地感染病例分布差异不显著,防治工作需要并重进行;境外输入病例的不均匀度比本地感染病例高,但在防治上均可以划分为5个重点集群。
