MMWR Morb Mortal Wkly Rep. 2009 Feb 13;58(5):115-9.
From September 28, 2008, to January 31, 2009, influenza activity remained low in the United States but began to increase at the end of January. Thus far during the 2008-09 influenza season, influenza A viruses have predominated and are antigenically related to the 2008-09 influenza vaccine strains. Oseltamivir resistance has been detected in nearly all of the influenza A (H1N1) viruses tested so far during the 2008-09 season, with high levels of adamantane resistance among influenza A (H3N2) viruses. This report summarizes U.S. influenza activity since the last update and reviews interim recommendations for the use of influenza antiviral medications.
从2008年9月28日至2009年1月31日，美国的流感活动水平一直较低，但在1月底开始上升。在2008 - 2009年流感季节到目前为止，甲型流感病毒占主导地位，并且在抗原性上与2008 - 2009年流感疫苗株相关。在2008 - 2009年季节到目前为止检测的几乎所有甲型（H1N1）流感病毒中都发现了对奥司他韦的耐药性，甲型（H3N2）流感病毒中金刚烷类耐药性水平较高。本报告总结了自上次更新以来美国的流感活动情况，并审查了关于使用流感抗病毒药物的临时建议。
