2004-2007年十堰市流行性感冒监测结果分析

目的　分析2004-2007年湖北省十堰市流行性感冒（流感）监测结果，初步探求本市流感病毒活动特点及其流行规律，寻求科学有效的防制对策。方法　常年开展流感流行病学和病原学监测，每年9月份开展血清学监测。结果　门诊流感样病例就诊比例每月变化趋势不太明显，儿童远高于成人比例；从1449份标本中分离流感病毒302株，分离率20.84%；月分离率在每年1-3月和7-9月分别出现冬季峰和夏季峰，冬季峰高于夏季峰；H3N2亚型、B型Victoria系流感病毒分别引起37起疑似流感暴发疫情中的9起和14起；健康人群各亚型流感病毒抗体水平每年都发生较大变化，其阳性率与该亚型流感病毒的流行强度一致。结论　十堰地区几乎全年均有流感病毒活动，呈现冬季峰高于夏季峰的双峰模式，H1N1、H3N2亚型与B型的Victoria系、Yamagata系流感病毒在本地区呈现此消彼长的流行规律；每年应在充分考虑本国流感流行特点和B型流感病毒复杂性的基础上提供疫苗组分；建议十堰市人群每年10-12月及时接种流感疫苗，增加中小学校和托幼机构学生的疫苗接种率。
