在国内首例COVID-19病例出现一年多后，美国还没有COVID-19监测数据分析和公开报告的国家标准。这导致了公共卫生机构在监测实践中的巨大差异，这些机构通过各种各样的日期来分析和呈现新确诊的病例，选择使用哪一个日期应该在可解释性和流行病学相关性之间取得平衡。报告日期易于解释，通常代表疫情趋势，并可在监测数据集中获得。这些特点使其成为公开报告和监测数据可视化的首选日期，尽管它不适合对疫情动态进行流行病学分析。症状发作日期由于其临床和流行病学相关性而更适合于此类分析。然而，使用症状发作来公开报告新的确诊病例可能会引起混乱，因为报告滞后会导致最近病例的人为下降。我们希望这次讨论是一个起点，朝着更标准化的方法进行基于日期的监测。这种标准化可以改善公众的理解、决策和疫情应对。
More than a year after the first domestic COVID-19 cases, the United States does not have national standards for COVID-19 surveillance data analysis and public reporting. This has led to dramatic variations in surveillance practices among public health agencies, which analyze and present newly confirmed cases by a wide variety of dates.The choice of which date to use should be guided by a balance between interpretability and epidemiological relevance. Report date is easily interpretable, generally representative of outbreak trends, and available in surveillance data sets. These features make it a preferred date for public reporting and visualization of surveillance data, although it is not appropriate for epidemiological analyses of outbreak dynamics. Symptom onset date is better suited for such analyses because of its clinical and epidemiological relevance. However, using symptom onset for public reporting of new confirmed cases can cause confusion because reporting lags result in an artificial decline in recent cases.We hope this discussion is a starting point toward a more standardized approach to date-based surveillance. Such standardization could improve public comprehension, policymaking, and outbreak response.
