To analyze the surveillance data of malaria in Tengchong County of Yunnan Province in 2013, so as to provide the evidence for carrying out the malaria elimination in the future.
The data of epidemic situation and surveillance of malaria in Tengchong County in 2013 were collected and analyzed for the prevalence state as well as and the monitoring indicators including the blood examination of fever patients of unknown origin, initiative detection of cases, under-reporting survey, sentinel surveillance and species and density investigation of Anopheles mosquitoes.
Totally 138 malaria cases were reported in Tengchong County in 2013, among which 118 cases were infected with Plasmodium vivax and 20 cases with P. falciparum, and all the reported cases were imported. The completion rates of blood examinations, case reports and case investigations all reached 100%. A total of 57 cases were involved in initiative detection, but no positive cases were found. The twice under-reporting of malaria case surveys were conducted and 1 case had been under-reported. The sentinel surveillance was carried out both in the domestic and overseas sites at the same time to detect the suspected malaria cases, 172 cases were screened totally, and 15 ones were detected as positives. Totally 528 returnees were screened, and there were no positive case found. A. sinensis and A. liangshanensis were the dominant species, followed by A. minimus, A. maculatus and others.
The malaria epidemic situation is stable in Tengchong County in 2013, and all the work in surveillance has been conducted successfully, but there still exist some difficulties in the process of malaria elimination. The local health departments should further strengthen the surveillance on imported cases and the management on migrant population as well as the capability building for health workers in malaria control in the future.
分析云南省腾冲县2013年疟疾监测数据，为今后开展消除疟疾工作提供依据。
收集腾冲县2013年疟疾疫情及监测资料，分析流行状况及不明原因发热病人血检、病例主动侦查、漏报调查、哨点监测、按蚊种类与密度调查等监测指标。
2013年腾冲县共报告疟疾病例138例，其中间日疟118例，恶性疟20例，均为输入性病例。血检、病例报告和病例调查完成率均达100%。主动侦查共57例，未发现阳性病例。开展2次疟疾病例漏报调查，发现漏报1例。同时开展国内外哨点监测，筛查疑似疟疾病例172例，检出阳性15例。共筛查归国人员528人，未发现阳性病例。中华按蚊和凉山按蚊为优势蚊种，其次为微小按蚊、黄斑按蚊等。
2013年腾冲县疟疾疫情稳定，各项监测工作顺利开展，但在消除疟疾过程中仍存在一些困难。今后当地卫生部门应进一步加强输入病例监测、流动人口管理及疟疾防治卫生人员能力建设。
