摘　　要：目的分析山西省消除疟疾后2019-2023年输入性疟疾病例流行病学特征,为山西省制定科学有效的疟疾防控策略提供参考依据。方法资料来源于中国疾病预防控制信息系统和寄生虫病防治信息管理系统,收集山西省2019-2023年输入性疟疾病例资料,采用描述性流行病学方法和SPSS 26.0软件进行统计学分析。结果2019-2023年山西省共报告疟疾病例51例,均为境外输入。其中恶性疟38例(74.51%)、卵形疟6例(11.77%)、间日疟5例(9.80%)、三日疟1例(1.96%)、混合感染1例(1.96%),无死亡病例;病例以男性(94.12%,48/51)和出国务工者(84.31%,43/51)为主;发病年龄中位数为37岁;无明显发病季节高峰;太原市报告病例最多(72.55%,37/51);病例感染来源以非洲地区(96.08%)为主,其中位居前5位的国家依次为刚果(金)(16例)、尼日利亚(6例)、赤道几内亚(5例)、莫桑比克(3例)、刚果(布)(3例);病例从发病至初诊间隔时间和初诊至确诊间隔时间的M(Q1,Q3)d分别为2(0,4)d和1(0,3)d,2019-2023年病例发病至初诊时间间隔的差异有统计学意义(H=17.41,P=0.048),初诊至确诊时间间隔的差异有统计学意义(H=20.82,P=0.010)。2019-2023年山西省不明原因发热病例血检数共101146人次,其中2020年血检数最少(19867人次),2023年血检数最多(20778人次)。结论山西省在消除疟疾后,2019-2023年疟疾病例均为境外输入性病例,仍需加强对疟疾高流行区往返人员的监测工作,实行医防结合,共同防控输入性疟疾疫情发生。Objective To analyze the epidemiological characteristics of imported malaria cases from 2019 to 2023 after the elimination of malaria in Shanxi Province,and provide reference for formulating scientific and effective malaria prevention and control strategies in Shanxi Province.Methods The data of imported malaria cases were collected China Information System for Disease Control and Prevention and National Parasitic Disease Control Information Management System in Shanxi Province,from 2019-2023.Descriptive epidemiological method and SPSS 26.0 statistical software were used for descriptive epidemiological statistical analysis.Results A total of 51 malaria cases were reported in Shanxi Province in 2019-2023,all imported from abroad.Among them,there were 38 cases of falciparum malaria(74.51%),6 cases of plasmodium ovale(11.77%),5 cases of plasmodium vivax(9.80%),1 case of plasmodium triticum malaria(1.96%),and 1 case of mixed infections(1.96%),with nodeaths;cases were predominantly males(94.12%,48/51)and workers who went abroad for work(84.31%,43/51);the median age of onset was 37 years old;and there were imported cases every month,with no obvious peak of incidence;Taiyuan City reported the most cases,accounting for 72.55%(37/51)of the total number of cases,the source of infection of cases was mainly from Africa(96.08%),with the Democratic Republic of the Congo(16 cases),Nigeria(6 cases),Equatorial Guinea(5 cases),Mozambique(3 cases),and Republic of the Congo(3 cases)in that order;the median time between the onset of disease and first diagnosis,and the median time between first diagnosis and confirmation,were two times longer than that of first diagnosis,and the median time between first diagnosis and confirmation was two times longer than that of first diagnosis.The M(Q1,Q3)intervals from onset to first diagnosis and from first diagnosis to confirmed diagnosis were 2(0,4)days and 1(0,3)days,respectively,with statistically significant differences between different years from onset to first diagnosis(H=17.41,P=0.048),a
