摘要
目的对2014年10月~2015年3月乌鲁木齐市流感病原学进行监测分析,以明确乌鲁木齐市2014~2015年流感病原学特征,为流感疫情防控提供科学依据。方法对流感样病例的咽拭子样本进行流感病毒核酸检测,并利用MDCK进行病毒分离,采用血凝试验（HA）进行流感病毒型别的鉴定。结果 2014年10月~2015年3月共检测流感病例咽拭子样本1 334份,核酸检测阳性的有258份,阳性率为19.34%,其中甲型H1N1型1份,H3N2型216份,乙型BY41份。流感高峰在11和12月份,年龄以5~14岁为高发人群。共分离到流感病毒52株,整体分离率为3.76%,其中H3N2型51株,乙型BY1株。结论加强对流感的实时监测及对流感高度易感人群的防护,对我市流感的防控工作具有重要意义。
Objective To monitor and analyze the etiology of influenza in Urumqi City, Xinjiang Uygur Autonomous Region, China from October 2014 to March 2015 so as to understand the etiological characters of influenza in Urumqi in this period and provide a scientific basis for prevention and control of influenza. Methods The pharynx swabs of patients with influenza-like symptoms were tested for influenza virus nucleic acid, from which virus was isolated by MDCK and identified for type by hemagglutination（HA）test. Results Of the 1 334 pharynx swab samples, 258 were positive for influenza virus nucleic acid, indicating a positive rate of 19. 34%, in which one was positive for influenza A subtype H1N1, 216 for H3N2 and 41 for influenza B subtype BY. The peak of epidemic appeared in November and December. Most of the cases were in the children at ages of 5 ~ 14 years. A total of 52 influenza virus strains were isolated, indicating a general isolation rate of 3. 76%, of which 51 were of subtype H3N2, and one was of subtype BY. Conclusion Strengthening the real-time monitoring on influenza and protection of highly susceptible population are of an important significance in pre-vention and control of influenza in Urumqi City.
