义乌市入境发热人群传染病分析

Analysis of infectious diseases among inbound fever population in Yiwu City

目的了解和分析义乌入境发热人员的情况,探讨更全面、科学的入境卫生检疫防控措施。方法收集2015年1月-2017年12月义乌市口岸入境发热人群(体温≥37. 5℃)的信息,同时采集咽拭子和/或血清标本、尿液标本,进行传染病检测分析。结果对送检的359例发热患者进行主要常见呼吸道病毒和虫媒病毒检测,共检出阳性96例,阳性率为26. 74%(96/359)。检出的病毒种类包括流感、副流感、肺炎支原体、登革热、寨卡和疟疾等。结论义乌口岸发热患者体征各有特点,来自非洲的人员以携带感染疟疾的风险最大,来自东南亚的旅客以携带感染登革热的风险最大,而来自中国港澳台的旅客主要以流感为主。检验检疫部门应大力加强口岸重点人员的监测力度。
