Abstract: Objective Objective To analyze the data of epidemic situation of malaria in Longlin Various Nationalities Autonomous County，Guangxi Zhuang Autonomous Region，China from 1951 to 2014 and discuss the distribution characteristics and epidem? ic law，so as to provide the evidences for developing the prevention and control strategies of the disease. Methods Methods The data about the epidemic situation of malaria in Longlin Various Nationalities Autonomous County were collected and analyzed statisti? cally with Excel 2007. Results Results Totally 93 460 malaria cases were reported from 1951 to 2014 in the county. There were two morbidity peaks of malaria during this period，namely 1950s and 1970s，and the annual average incidence rates were 3 237.94/ 100 000 and 1 572.12/100 000，respectively，but it began to flatten after 1980s. Before 2000，the local cases were the main type，however，there were no endogenous cases since 2008. In 1950s，falciparum malaria was the main type of the disease，and the cases with falciparum malaria，tertian malaria and quartan malaria were accounted for 45.01%（2 392/5 314），33.72% （1 792/5 314） and 19.55% （1 039/5 314） ，respectively；while in 1960s，the proportion of cases with tertian malaria increased， that of the cases with quartan malaria decreased，and there were no quartan malaria cases reported since 1980s. There were im? ported malaria cases reported since 1990s，and a total of 51 cases were found in this period，among which，50 cases（98.04%） were tertian malaria，and the main infection sources were the cases from epidemic areas in other provinces of China. After 2000， the imported malaria cases with falciparum malaria increased，with a proportion of 60.00%（21/35），and the infection sources were mainly from Africa and Southeast Asia. Conclusions Conclusions The local endemic of malaria in Longlin Various Nationalities Auton? omous County has been effectively controlled，but the situation of imported malaria is still severe in this county. Therefore， strengthening the surveillance of floating population，especially the workers backing from overseas，is still the key of malaria prevention and control in the future.

摘要： 目的 目的 分析1951-2014年隆林各族自治县疟疾疫情资料， 探讨疟疾分布特征及流行规律， 为制定防控策略提供 依据。方法 方法 收集1951-2014 年广西隆林各族自治县疟疾疫情资料， 采用Excel 2007软件进行统计分析。结果 结果 1951- 2014年隆林各族自治县共报告疟疾病例93 460例。疟疾发病有两个高峰期， 分别为20世纪50年代和70年代， 年均疟疾 发病率分别为3 237.94/10万和1 572.12/10万； 20世纪80年代后疫情趋于平缓。2000年以前本地病例为主要病例类型， 2008年后再无内源性疟疾病例报告。20世纪50年代病例以恶性疟为主， 占45.01% （2 392/5 314）； 间日疟和三日疟次之， 分别占33.72% （1 792/5 314） 和19.55% （1 039/5 314）； 20世纪60年代后以间日疟为主， 所占比例呈升高趋势； 三日疟所占 比例呈下降趋势， 20世纪80年代后再无报告。20世纪90年代开始有输入性疟疾病例报告， 该时期共报告51例， 以间日 疟为主， 占98.04% （50/51）， 感染来源主要为国内疟疾流行疫区； 2000年以后以恶性疟为主， 占60.00% （21/35）， 感染来源 主要为非洲、 东南亚国家和地区。结论 结论 广西隆林各族自治县当地疟疾流行得到有效控制， 但输入性疟疾疫情严峻， 加 强流动人口尤其是国外务工返乡人员的监测是当前及今后疟防工作的重点。
