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.
2020 年 4 月，向国家疫情报告系统报告的诺如病毒疫情爆发的发生率显著下降。我们使用回归模型来确定这种下降是否是由于报告不足、季节性趋势，还是由于为应对严重急性呼吸系统综合征冠状病毒 2 而实施的非药物干预措施（NPIs）而导致的接触减少造成的，使用了 2012 年 7 月至 2020 年 7 月来自 9 个州的数据。诺如病毒疫情在所有 9 个州均显著下降，报告不足和/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相似。NPIs 似乎降低了非呼吸道病原体诺如病毒的发病率。
