摘要 目的掌握锦州市流感流行情况,分析主流病毒类型,为更好地预防流感疫情提供依据。方法自2009年2月1日起常年开展流感流行病学和病原学监测,同年5月份开展血清学监测。对两个年度的监测资料进行描述性流行病学分析,监测资料包括哨点医院收集门诊流感样病例(以下简称ILI)就诊信息,以及来自哨点医院监测系统和暴发疫情所收集的ILI标本的病原学监测资料。结果流感样病例占门诊病例总数的3.3%,流感样病例年龄分布年轻化,年龄在<25岁的病例占总流感样病例数的72.73%。病原学监测显示流感病毒的BV亚型为本地区主流病毒株型,占总监测毒株的68%。结论锦州市流感未出现暴发疫情,但流感样病例在2009年出现了病例聚集现象。病原学监测连续两年流感Bv毒株为主流病毒,人群获得一定免疫,未来一段时间有改变主力毒株的可能。
