In their model, David Baud and colleagues exclude individuals who die within 14 days of testing positive for severe acute respiratory syndrome coronavirus 2. If an individual contracts symptoms on March 1, tests positive on March 10, and dies on March 11, they would not be included in the denominator for case fatality rate (CFR) on March 11. In addition, patients might test positive up to 13 days after recovery. As testing is expanded, an asymptomatic patient infected 1 week before testing positive on March 3 should, but will not, be included in calculations for March 16.

估计COVID-19的病死率。

在他们的模型中，David Baud及其同事排除了在严重急性呼吸系统综合症冠状病毒2呈阳性的14天内死亡的人。如果一个人在3月1日出现症状，在3月10日呈阳性，而在3月11日死亡，则他们不会被纳入3月11日病死率（CFR）的分母中。此外，患者可能在康复后长达13天呈阳性反应。随着测试范围的扩大，在3月3日测试呈阳性的1周前被感染的无症状患者应（但不会）包括在3月16日的计算中。
