2009年4月甲型H1N1流感大流行病毒的出现和随后的传播导致了21世纪的第一次大流行。这一历史性事件与2009年夏季和秋季以及2010年冬季期间美国流感活动的时间和受影响人员的不寻常模式有关。美国流感监测系统确定了两波不同的H1N1大流行性流感活动——第一次高峰出现在2009年6月，第二次高峰出现在2009年10月。所有流感监测组成部分显示，流感活动水平高于夏末和初秋通常出现的水平。在此期间，流感活动在截至2009年10月24日的一周内达到最高水平。本报告总结了2009年4月12日至2010年3月27日美国流感监测数据。
The emergence in April 2009 and subsequent spread of the 2009 pandemic influenza A (H1N1) virus resulted in the first pandemic of the 21st century. This historic event was associated with unusual patterns of influenza activity in terms of the timing and persons affected in the United States throughout the summer and fall months of 2009 and the winter of 2010. The US Influenza Surveillance System identified 2 distinct waves of pandemic influenza H1N1 activity-the first peaking in June 2009, followed by a second peak in October 2009. All influenza surveillance components showed levels of influenza activity above that typically seen during late summer and early fall. During this period, influenza activity reached its highest level during the week ending 24 October 2009. This report summarizes US influenza surveillance data from 12 April 2009 through 27 March 2010.
