2017-2022年广西口岸入境人员登革热监测结果分析

Surveillance of Dengue Fever at Guangxi Port from 2017 to 2022

目的分析2017—2022年广西口岸入境人员登革热监测结果及流行病学特征,为广西登革热防控提供科学依据。方法收集2017—2022年广西口岸入境体温异常的旅客信息,采集其血样或尿样,使用实时荧光RT-PCR方法进行登革病毒及分型检测。结果2017—2022年广西口岸共监测入境发热旅客307例,检出登革病毒24例,阳性率为7.82%;其中DENV-1型18例(75.00%)、DENV-2型5例(20.83%)、DENV-4型1例(4.17%),未监测到DENV-3型。24例病例中来自东南亚国家的有22例,依次为越南10例、柬埔寨5例,老挝2例,缅甸2例,泰国2例,新加坡1例。结论广西口岸登革热输入风险主要来自越南和柬埔寨,应加强来自上述地区人员的检验检疫,同时提高出境人群的登革热预防意识,降低因输入性病例导致本地疫情暴发的风险。
