2020年4月，向国家疫情报告系统报告的诺如病毒疫情发生率急剧下降。使用2012年7月至2020年7月9个州的数据，我们使用回归模型来确定这种下降是否最好地解释为漏报、季节性趋势或由于对严重急性呼吸综合征冠状病毒2实施的非药物干预措施（npi）导致的暴露减少。诺如病毒暴发的减少在所有9个州都很显著，漏报和/或季节性不太可能是这些发现的主要解释。这些模式在各种环境中都是相似的。npi似乎降低了诺如病毒（一种非呼吸道病原体）的发病率。
In April 2020, the incidence of norovirus outbreaks reported to the National Outbreak Reporting System dramatically declined. We used regression models to determine if this decline was best explained by underreporting, seasonal trends, or reduced exposure due to nonpharmaceutical interventions (NPIs) implemented for severe acute respiratory syndrome coronavirus 2 using data from 9 states from July 2012 to July 2020. The decline in norovirus outbreaks was significant for all 9 states, and underreporting and/or seasonality are unlikely to be the primary explanation for these findings. These patterns were similar across a variety of settings. NPIs appear to have reduced incidence of norovirus, a nonrespiratory pathogen.
