We investigated the infectivity of 128 severe acute respiratory disease coronavirus 2-associated deaths and evaluated predictive values of standard diagnostic procedures. Maintained infectivity (20%) did not correlate with viral RNA loads but correlated well with anti-S antibody levels. Sensitivity >90% for antigen-detecting rapid diagnostic tests supports their usefulness for assessment.
我们研究了 128 例严重急性呼吸综合征冠状病毒 2 相关死亡病例的传染性，并评估了标准诊断程序的预测值。维持传染性（20%）与病毒 RNA 载量无关，但与抗-S 抗体水平密切相关。抗原检测快速诊断检测的敏感性>90%支持其在评估中的有用性。
