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.

死后抗原检测快速诊断测试可预测 SARS-CoV-2 相关死亡的传染性

我们调查了 128 例严重急性呼吸道疾病冠状病毒 2 相关死亡的传染性，并评估了标准诊断程序的预测价值。保持感染性 (20%) 与病毒 RNA 载量无关，但与抗 S 抗体水平相关。抗原检测快速诊断测试的灵敏度 >90% 支持其评估的有用性。
