Abstract
In October 2009, a new genogroup II, type 4 (GII.4) norovirus variant was identified in the United States. We collected norovirus outbreak data from 30 states to assess whether this new strain was associated with increased acute gastroenteritis activity. No increase in norovirus outbreaks was observed during the 2009-2010 winter.
摘要
2009 年 10 月，美国发现了一种新型基因 II 组 4 型（GII.4）诺如病毒变异株。我们收集了来自 30 个州的诺如病毒爆发数据，以评估这种新菌株是否与急性肠胃炎活动增加有关。在 2009-2010 年冬季，并未观察到诺如病毒爆发的增加。
