COVID symptom screening, a new workplace practice, is already affecting many millions of American workers. As of this writing, 34 states already require, and federal guidance recommends, frequent screening of at least some employees for fever or other symptoms. This paper provides the first empirical work identifying major features of symptom screening in a broad population and exploring the trade‐offs employers face in using daily symptom screening. First, we find that common symptom checkers could screen out up to 7 percent of workers each day, depending on the measure used. Second, we find that the measures used will matter for three reasons: Many respondents report any given symptom, survey design affects responses, and demographic groups report symptoms at different rates, even absent fluctuations in likely COVID exposure. This last pattern can potentially lead to disparate impacts and is important from an equity standpoint.

在工作场所进行隐性症状筛查时，谁进进出出？

COVID症状筛查是一种新的工作场所实践，已经影响到数百万的美国工人。截至撰写本文时，已有34个州已经要求并且联邦指南建议对至少一些雇员进行频繁的发烧或其他症状筛查。本文提供了第一项实证工作，确定了广泛人群中症状筛查的主要特征，并探讨了雇主在使用每日症状筛查时所面临的取舍。首先，我们发现常见的症状检查员每天可以筛查多达7％的工人，具体取决于所使用的措施。其次，我们发现所使用的措施具有三个原因：许多受访者报告了任何给定的症状，调查设计影响了响应，人口统计群体报告的症状发生率不同，即使可能的COVID暴露量没有波动。
