Abstract: Objective To understand the trend and epidemiologic characteristics of malaria prevalence so as to provide the evidence for further control of the disease in Liaoning Province. Methods The data of registered cases of malaria in Liaoning Province from 2008 to 2013 were collected and analyzed with the descriptive epidemiological methods. Results A total of 202 ma? laria cases were reported from 2008 to 2013. There was no epidemic outbreak,and the average annual incidence was 0.08/ 100 000. Totally 17 P. v. cases of local infection were reported,and 185 imported malaria cases were reported(P.v. 33 cases,P.f. 113 cases,P.v. & P.f. 13 cases,P.o. 3 cases,and unspecified 23 cases) . The ratio of male to female was 5.91: 1,the populations aged 31?45 years were the most(47.52%),and the main occupation was exported labors(46.04%) . The 179 imported cases were infected in Africa and Southeast Asia,6 imported cases were infected in Anhui Province,Yunnan Province and Hongkong,and 16 local cases were infected in the border area of Dandong City. Conclusions Although the annual incidence of malaria in Liaon? ing Province is lower than 1/10 000,the incidence shows an increasing trend because the exported labors are increased. There? fore, the epidemic monitoring and health education should be strengthened, especially for the exported labors who have returned.

摘要: 目的 目的 了解2008-2013年辽宁省疟疾流行趋势和特征, 为制定控制对策提供依据。方法 方法 收集2008-2013年辽 宁省疟疾疫情数据, 采用描述性流行病学方法进行统计分析。结果 结果 2008-2013年辽宁省共报告疟疾病例202例, 均为散 在病例, 无暴发流行等疫情, 年平均发病率为0.08/10万。共报告本地感染病例17例 (均为间日疟), 输入性病例185例 (其 中间日疟33例, 恶性疟113例, 恶性疟和间日疟混合感染13例, 卵形疟3例, 未分型23例)。报告病例的男女比例5.91∶1, 年龄以31~45 岁最多, 占47.52%; 职业主要以赴境外劳务回归人员为主, 占46.04%。输入性病例中有179例的感染地为 非洲、 东南亚等境外疟疾高发地区, 6例为安徽、 云南和香港等国内其他省区; 本省感染病例中有16例的感染地为丹东市边 境地区。结论 结论 辽宁省疟疾年发病率虽然低于1/10万, 但因赴境外劳务回归的输入性疟疾病例呈逐年增多趋势。今后应 加强劳务输出回归人员的疫情监测、 健康教育等管理工作, 持续开展发热病人监测、 处置现患病例和疟原虫基因溯源工 作, 防止继发二代病例、 降低疟疾传播与流行的风险。
