2023 Respiratory Virus Response - NSSP Emergency Department Visit Trajectories by State- COVID-19, Flu, RSV, Combined

2023 Respiratory Viruses Response – National Syndromic Surveillance Program Emergency Department Visit Trajectories - COVID-19, Flu, RSV, Combined – by state. This dataset provides the percentage of emergency department patient visits for the specified pathogen of all ED patient visits for the specified geography that were observed for the given week from data submitted to the National Syndromic Surveillance Program (NSSP). In addition, the trend over time both as of the given row date and as of the most current data submitted is characterized as increasing, decreasing or stable to provide awareness of how the weekly trend is changing for the given geographic region.

For the emergency department time series, trajectory classifications reported on the opening page are based on rolling regression model assessments of the slope for each respiratory illness. Weeks with a significant time term (p <0.05) are classified as increasing when the slope is positive and decreasing when the slope is negative. Weeks with a non-significant time term (p ≥ 0.05) are classified as stable. A 3-week moving average is applied to the time series prior to the regression procedure in order to smooth week-to-week variation.

2023年呼吸道病毒应对——国家综合征监测计划急诊室就诊轨迹——COVID-19、流感、RSV、混合型——按州划分。本数据集提供了特定地理区域内急诊室患者就诊中，针对指定病原体就诊的患者就诊比例，该比例基于提交至国家综合征监测计划（NSSP）的给定周数据。此外，时间序列的趋势，无论是基于给定行日期还是基于最新提交的数据，均被描述为增长、下降或稳定，以提供特定地理区域每周趋势变化的认知。对于急诊室的时间序列，首页上报告的轨迹分类基于对每种呼吸道疾病的斜率的滚动回归模型评估。当斜率为正时，具有显著时间项（p < 0.05）的周被归类为增长；当斜率为负时，被归类为下降。当时间项不具有显著性（p ≥ 0.05）时，被归类为稳定。在回归程序之前，对时间序列应用3周移动平均，以平滑周与周之间的变化。欲了解更多信息，请参阅：<a href="https://www.cdc.gov/ncird/surveillance/respiratory-illnesses/index.html#companion-guide"><b>配套指南：NSSP急诊室呼吸道疾病数据</b></a>。数据每周五更新一次。
