目的 分析2004-2015年丹阳市疟疾流行特征,为科学制定防治策略提供依据。方法 收集2004-2015年丹阳市疟疾血检统计数据、传染病报告信息管理系统上报的疟疾病例与流行病学个案调查表,以及2008-2015年蚊媒监测数据等,进行统计分析。结果 2004-2015年丹阳市累计报告疟疾病例58例,年平均发病率为0.60/10万。其中间日疟占65.52%(38/58),恶性疟占5.17%(3/58),卵形疟占1.72%(1/58),未分型占27.59%(16/58)。本地感染病例占31.03%(18/58),输入性病例占68.97%(40/58);2011年起无本地感染病例发生。中华按蚊作为丹阳市唯一的疟疾传播媒介在境内仍普遍存在,但密度较低。结论 输入性疟疾严重威胁丹阳市消除疟疾成果,需加强输入性疟疾疫情的监测和处置。
Objective To analyze the epidemiological characteristics of malaria in Danyang City from 2004 to 2015 and provide the basis for scientific prevention and control strategies. Methods The data of malaria blood tests in Danyang from 2004 to 2015, malaria cases and epidemiological questionnaires reported by the Communicable Disease Reporting Information Management System and the mosquito-borne surveillance data from 2008 to 2015 were collected for statistical analysis. Results A total of 58 malaria cases were reported in Danyang City from 2004 to 2015, with an average annual incidence of 0.60 / 100,000. Among them, 65.52% (38/58) of Plasmodium falciparum, 5.17% (3/58) of Plasmodium falciparum, 1.72% (1/58) of Ovovirosis, and 27.59% (16/58) of Upphotropic malaria cases. Local infections accounted for 31.03% (18/58), imported cases accounted for 68.97% (40/58); no cases of local infection since 2011. Anopheles sinensis, as the sole malaria transmission medium in Danyang City, is still widespread in China but its density is relatively low. Conclusions Imported malaria is a serious threat to the elimination of malaria in Danyang. The monitoring and disposal of imported malaria should be strengthened.
