摘　　要：目的分析2013年南宁口岸回国人员中发现的5例输入性登革热病例的流行病学特征,为出入境登革热监测和制定防治对策提供科学依据。方法对2013年南宁口岸回国人员体检中发现的5例登革热病例资料进行分析,同时采用ELISA法和实时荧光RT-PCR两种方法进行检测。结果 5例病例均为输入性实验室确诊病例,来自登革热疫区,出现乏力、发热、头痛等临床症状,4例患者的DEV-Ig M呈阳性,1例呈阴性,5例的登革病毒实时荧光RT-PCR结果均呈阳性。结论荧光RT-PCR具有较高的敏感性,适用于登革热早期诊断。近几年南宁市报告的输入性登革热病例增多,应加强进出口岸及边境地区的监测和防控,避免出现因输入病例引起的本地感染或局部暴发疫情。Objective This article analyzes the epidemiological characteristics of five imported cases of dengue fe- ver at Nanning port and provides a scientific basis to the surveillance of and countermeasures to the entry Dengue Fever.
