摘要
目的分析2011—2015年营口市流感流行特征及流感流行优势毒株的分布,为控制流感提供科学依据。方法对2011—2015年营口市监测哨点医院流感样病例(influenza like illness,ILI)监测资料、病原学监测资料进行分析。结果2011—2015年共分离到流感毒株185株,总阳性率为4.48%,新甲型H1N1为优势株,病原学监测结果呈现多种流感病毒交替或混合流行的特点,分布有明显的季节性。对ILI%与流感毒株检出率进行秩相关分析,相关系数为0.174(P<0.01),呈正相关。结论流感流行呈现秋冬季高峰,流行毒株优势株随时间变化而不同,仍需扩面加强监测。
OBJECTIVE To analysis epidemiological characteristics of influenza and the distribution of predominantvirus strain in Yingkou from 2011 to 2015, and provide evidence for the prevention and control of influenza. METHODS Descriptive analysis was conducted on the incidence data of influenza like illness （ILI） and pathogen surveillance results from the influenza sentinel hospitals in Yingkou from 2011 to 2015. RESULTS Totally 185 strains of influenza viruses were isolated during 2011 to 2015, the isolation rate was 4.48%. novel influenza A （H1N1） was predominant during the whole surveillance period. Etiological surveillance results re- vealed that muhitype viruses circulated a alternatively or co-circulated with obvious seasonality. The ILI proportion was positively cor- related with virus isolation rate （correlation coefficient： 0.174, （P〈0.01）. CONCLUSION The incidence peaks of influenza were in spring and winter in Yingkon. The predominant strain varied with season and extended monitoring surface.
