Abstract

During May 24–September 5, 2015, the United States experienced typical low levels of seasonal influenza activity. Influenza A (H1N1)pdm09 (pH1N1), influenza A (H3N2), and influenza B viruses were detected worldwide and were identified sporadically in the United States. All of the influenza viruses collected from U.S. states and other countries during that time have been characterized antigenically and/or genetically as being similar to the influenza vaccine viruses recommended for inclusion in the 2015–16 Northern Hemisphere vaccine. During May 24–September 5, 2015, three influenza variant† virus infections were reported; one influenza A (H3N2) variant virus (H3N2v) from Minnesota in July, one influenza A (H1N1) variant (H1N1v) from Iowa in August, and one H3N2v from Michigan in August.

摘要

2015 年 5 月 24 日至 9 月 5 日期间，美国经历了典型的低季节性流感活动水平。甲型 H1N1pdm09（pH1N1）、甲型 H3N2 和乙型流感病毒在全球范围内被检测到，并在美国零星被发现。在此期间，从美国各州和其他国家收集的所有流感病毒在抗原和/或遗传特征上均与推荐用于 2015-16 北半球疫苗的流感疫苗病毒相似。2015 年 5 月 24 日至 9 月 5 日期间，报告了三例流感变异†病毒感染病例；7 月，明尼苏达州报告了一例甲型 H3N2 变异（H3N2v）病毒，8 月，爱荷华州报告了一例甲型 H1N1 变异（H1N1v）病毒，8 月，密歇根州报告了一例 H3N2v 病毒。
