This report summarizes U.S. influenza activity during October 2-December 17, 2016. Influenza activity in the United States remained low in October and has been slowly increasing since November. Influenza A viruses were identified most frequently, with influenza A (H3N2) viruses predominating. Most influenza viruses characterized during this period were genetically or antigenically similar to the reference viruses representing vaccine components recommended for production in the 2016-17 Northern Hemisphere influenza vaccines.
本报告总结了 2016 年 10 月 2 日至 12 月 17 日期间美国的流感活动情况。10 月美国的流感活动仍然较低,自 11 月以来一直在缓慢增加。最常鉴定到的病毒是甲型流感病毒,其中甲型(H3N2)病毒占主导地位。在此期间鉴定到的大多数流感病毒在遗传或抗原上与代表 2016-17 北半球流感疫苗生产推荐疫苗成分的参考病毒相似。
