摘　　要：目的分析山东省境外输入性疟疾流行病学特征,为疟疾防控提供参考。方法收集山东省2023年通过中国疾病预防控制中心传染病监测信息系统上报的境外输入性疟疾病例信息,对感染类型、感染次数、从入境到发病时间、从发病到确诊时间等开展分析。结果2023年山东省报告的51例境外输入性疟疾,主要从非洲输入(98.04%),以30~49岁男性劳务(74.51%)、恶性疟(78.43%)为主;从入境到发病平均时间为15.65 d、中位时间为8 d,从发病到确诊平均时间为3.96 d、中位时间为4 d,不同感染类型病例从入境到发病时间差异有统计学意义(t=5.781,P=0.006),不同感染次数病例从入境到发病时间(t=2.690,P=0.078)以及不同感染类型(t=0.510,P=0.604)、不同感染次数(t=0.445,P=0.643)病例从发病到确诊时间差异均无统计学意义(P>0.05);劳务人员在境外卫生条件最差、防蚊措施最少、感染3次及以上的比例(42.11%)最高。结论山东省2023年境外输入性疟疾的主要来源地区为非洲,重点人群为30~49劳务男性,主要感染类型为恶性疟。Objective To analyze the epidemiological characteristics of imported malaria in Shandong province,provide reference for the prevention and control of malaria.Methods The data of imported malaria cases reported in 2023 by Shan dong through China Disease Prevention and Control Information System was collected.The infection type and times,the time from entry to onset,from onset to diagnosis were analyzed.Results A total of 51 imported malaria cases were reported in Shandong,2023.The cases were mainly imported from Africa(98.04%),mainly male labor workers aged 30-49 years(74.51%).The infection type was mainly falciparum malaria(78.43%).From entry to onset,it took 15.65 d for average,8 d in median.From onset to definitive diagnosis,it took 3.96 d for average,4 d in median.The time from entry to onset was significantly different among different types of infection(t=5.781,P=0.006),there was no significant difference in the time from entry to onset among different times of infection(t=2.690,P=0.078),and there was no significant difference in the time from onset to definitive diagnosis among the cases with different infection type(t=0.510,P=0.604)and different infection times(t=0.445,P=0.643).The labor workers lived in the worst sanitary conditions abroad,the fewest anti-mosquito measures and the highest proportion(42.11%)of three or more infections.Conclusion In 2023,the main source region of imported malaria cases in Shandong province was Africa,the key population were 30-49 male labor workers,and the main infection type was falciparum malaria.
