人们对利用呈现的症状来优先进行COVID-19检测和建立基于COVID-19的监测非常感兴趣。然而，目前对COVID-19症状的特异性知之甚少。为了评估基于呼吸道病毒的COVID-19筛查的可行性，我们使用了我们卫生系统中常见呼吸道病毒和SARS-CoV-2的检测数据，以衡量根据症状对病毒检测结果进行正确分类的能力。基于这些结果，基于SARS的筛查可能不是识别应进行SARS-CoV-2感染检测的个体或获得新COVID-19病例领先指标的有效策略。
There is substantial interest in using presenting symptoms to prioritize testing for COVID-19 and establish symptom-based surveillance. However, little is currently known about the specificity of COVID-19 symptoms. To assess the feasibility of symptom-based screening for COVID-19, we used data from tests for common respiratory viruses and SARS-CoV-2 in our health system to measure the ability to correctly classify virus test results based on presenting symptoms. Based on these results, symptom-based screening may not be an effective strategy to identify individuals who should be tested for SARS-CoV-2 infection or to obtain a leading indicator of new COVID-19 cases.
