Analyses of US laboratory surveillance data during 1991 to 2004 established annual peak rotavirus activity occurred first in the Southwest and last in the Northeast. We compared spatiotemporal patterns during the 2 years preceding vaccine introduction in 2006 with the first 2 years following introduction. The postvaccine introduction years failed to demonstrate the typical Southwest to Northeast spread of rotavirus activity.
对 1991 年至 2004 年美国实验室监测数据的分析表明，每年轮状病毒活动的高峰期首先出现在西南部，最后出现在东北部。我们比较了 2006 年疫苗引入前的前 2 年和引入后的前 2 年的时空模式。疫苗引入后的年份未能显示出轮状病毒活动从西南到东北的典型传播。
