摘要目的 分析江西省2010-2014年疟疾流行病学特征,为制订全省疟疾防治对策提供依据.方法 自中国疾病预防控制中心传染病监测信息报告管理系统和寄生虫病报告信息管理系统收集2010-2014年江西省疟疾疫情数据和疟疾病例个案调查数据,采用描述流行病学的方法进行分析,包括地区、时间、人群分布等.结果 2010-2014年江西省共报告疟疾218例,年平均发病率为0.097 3/10万,死亡病例1例,病死率为0.46％(1/218).①地区分布:全省11个设区市100个县(市、区)中有65个县(市、区)报告了疟疾病例,病例报告数前三位的县(区)是青山湖区(22例)、南昌县(15例)、进贤县(13例),三者合计为50例,占全省总病例数的22.94％(50/218).②时间分布:全年均有病例报告,无明显的季节性.③人群分布:男女性别比为30.14:1.00;主要发病年龄在20～＜60岁,其构成比达94.49％(206/218),其中以40～＜50岁年龄组为最高,达32.11％(70/218);发病以农民、工人和民工为主,三者合计131例,占全省总病例数的60.09％(131/218);主要输入来源地为非洲和东南亚,分别占境外输入病例的76.19％(160/210)、19.52％(41/210).结论 江西省2010-2014年疟疾疫情稳中有升,输入性疟疾的防控将成为今后的主要工作.

abstractsObjective To analyze the epidemiological characteristics of malaria in Jiangxi Province from 2010 to 2014 and to provide a reference for malaria control in the whole province.Methods Data on malaria cases in Jiangxi Province from 2010 to 2014 were collected through the Disease Reporting Information System of Chinese Center for Disease Control and Prevention and Information System for Parasitic Diseases Control and Prevention.Descriptive epidemiological method was used to analyze the area distribution,time distribution and population distribution of the malaria cases.Results A total of 218 malaria cases were reported from 2010 to 2014 in the province,with an annual mean incidence of 0.097 3/100 000.One dead case was reported with a fatality rate of 0.46％(1/218).Of all 11 prefectures and 100 counties (cities,districts) in Jiangxi,65 counties (cities,districts)reported malaria cases.The top three counties (cities,districts) of malaria cases were Qingshanhu (22),Nanchang (15)and Jinxian (13),totally accounting for 22.94％ (50/218).The cases were reported through the whole year,without obvious seasonal peak.The ratio of male to female was 30.14:1.00.The age of the cases mainly distributed around the ages of 20-＜ 60 years,accounting for 94.49％ (206/218).The peak appeared in 40-＜ 50 years group,accounting for 32.11％ (70/218).The three major occupations of the cases were farmer,worker and migrant worker (131,60.09％).The cases were mainly imported from Africa and Southeast Asia,whose proportion of imported cases was 76.19％ (160/210) and 19.52％ (41/210),respectively.Conclusions The incidence of malaria is stable with a slight increase in Jiangxi Province from 2010 to 2014.Control of imported malaria cases will be the main task in the future.
