We obtained 24 air samples in 8 general wards temporarily converted into negative-pressure wards admitting coronavirus disease 2019 (COVID-19) patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron variant BA.2.2 in Hong Kong. SARS-CoV-2 RNA was detected in 19 (79.2%) of 24 samples despite enhanced indoor air dilution. It is difficult to prevent airborne transmission of SARS-CoV-2 in hospitals.
我们在香港获得了 24 个空气样本，这些样本来自 8 个普通病房，这些病房临时转换为负压病房，用于收治感染严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）奥密克戎变异株 BA.2.2 的 2019 年冠状病毒病（COVID-19）患者。尽管室内空气稀释得到增强，但仍在 24 个样本中的 19 个（79.2%）样本中检测到 SARS-CoV-2 RNA。在医院中很难预防 SARS-CoV-2 的空气传播。
