目的分析2014年山东省疟疾疫情现状及流行特征,为采取有针对性的防治策略和措施提供科学依据。方法在中国疾病预防控制系统传染病报告信息管理系统中,收集2014年山东省疟疾疫情资料及疟疾病例个案调查资料,采用Excel 2007建立数据库,对疟疾疫情流行病学特征及病例诊治情况进行统计分析。结果 2014年山东省共报告疟疾病例150例,较2014年的131例上升14.50%。除1例为云南省输入外,其他均为境外输入性病例,感染来源地区主要为非洲(142例,占95.30%)。150例病例均为实验室确诊病例,其中恶性疟121例(80.67%)、间日疟16例(10.67%)、卵形疟9例(6.00%)、三日疟4例(2.67%)。病例主要分布在泰安(40例,占26.67%)、烟台(17例,占11.33%)、威海(13例,占8.67%)、济宁(11例,占7.33%)和菏泽(11例,占7.33%)5市。结论山东省已连续3年无本地感染病例报告,但境外输入性病例报告数呈上升趋势,且感染虫种呈多样性。境外输入性疟疾是当前该省疟疾防控工作的重点。
Objective To analyze the status quo and epidemic characteristics of malaria in Shandong Province in 2014 and provide scientific basis for taking targeted prevention and control strategies and measures. Methods In China CDC Infectious Diseases Reporting Information Management System, the data of malaria cases and malaria cases collected from Shandong Province in 2014 were collected. The databases of Excel 2007 were set up to analyze the epidemiological characteristics of malaria and the diagnosis and treatment of malaria cases . Results A total of 150 malaria cases were reported in Shandong Province in 2014, an increase of 14.50% compared with 131 cases in 2014. Except for 1 case being input from Yunnan Province, the others were all imported cases. The main source of infection was Africa (142 cases, 95.30%). All the 150 cases were confirmed by laboratory tests, of which 121 cases (80.67%) were Plasmodium falciparum, 16 cases (10.67%) were Plasmodium vivax, 9 cases (6.00%) were Plasmodium ovale and 4 cases (2.67%) were Plasmodium malariae. The cases were mainly located in Taian (40 cases, 26.67%), Yantai (17 cases, 11.33%), Weihai (13 cases, 8.67%), Jining (11 cases, 7.33%) and Heze 7.33%) 5 cities. Conclusion Shandong Province has reported no cases of local infection for three consecutive years. However, the number of reported imported cases is on the rise, and the number of infected worms is diversified. Foreign malaria input is currently the focus of malaria prevention and control in this province.
