在钻石公主号邮轮爆发COVID-19疫情期间，我们在乘客和船员撤离船舱后对环境表面进行了采样。在撤离后1-17天的病例舱601份样本中，58份（10%）检测到SARS-CoV-2 RNA，而非病例舱未检测到。有症状病例（15%，28/189;循环定量[Cq]，29.79-38.86）和无症状病例（21%，28/131; Cq，26.21-38.99）的检出率无差异。没有从任何样本中分离出SARS-CoV-2病毒。有症状和无症状患者传播SARS-CoV-2的风险可能相似，表面可能参与传播。
During a COVID-19 outbreak on the Diamond Princess cruise ship we sampled environmental surfaces after passengers and crew vacated cabins. SARS-CoV-2 RNA was detected in 58 of 601 samples (10%) from case cabins 1-17 days after cabins were vacated but not from noncase cabins. There was no difference in detection proportion between cabins of symptomatic (15%, 28/189; cycle quantification [Cq], 29.79-38.86) and asymptomatic cases (21%, 28/131; Cq, 26.21-38.99). No SARS-CoV-2 virus was isolated from any of the samples. Transmission risk of SARS-CoV-2 from symptomatic and asymptomatic patients may be similar and surfaces could be involved in transmission.
