论文摘要
我们分析了使用筛查CT扫描评估潜在的Covid-19感染的效果，以根据病毒肺炎诊断来隔离和进行接触跟踪。然后，根据共同诊断，将RT-PCR用于持续隔离。 CT-扫描的低假负率和快速结果都导致传播大大降低。与PCR本身相比，60天后的案件减少了CT扫描筛查，$ 50 \ times $，降低有效的复制率$ r（t）$为$ 0.20 $。我们的结果表明，通过将社会距离与CT扫描和接触跟踪相结合，可以更快地灭绝Covid。
We analyze the effect of using a screening CT-scan for evaluation of potential COVID-19 infections in order to isolate and perform contact tracing based upon a viral pneumonia diagnosis. RT-PCR is then used for continued isolation based upon a COVID diagnosis. Both the low false negative rates and rapid results of CT-scans lead to dramatically reduced transmission. The reduction in cases after 60 days with widespread use of CT-scan screening compared to PCR by itself is as high as $50\times$, and the reduction of effective reproduction rate $R(t)$ is $0.20$. Our results imply that much more rapid extinction of COVID is possible by combining social distancing with CT-scans and contact tracing.
