背景：2019冠状病毒病（COVID-19）以医院传播风险为特征；然而，环境污染的程度及其对SARS-CoV-2传播的潜在贡献尚不清楚。本研究旨在探讨环境污染是否可能在SARS-CoV-2传播中发挥作用。方法：采用自然降水法采集空气样本，采用常规表面拭子法采集环境表面样本。采用逆转录聚合酶链反应检测SARS-CoV-2 RNA。结果：44份空气样本中未检出病毒RNA。医学区200份环境表面样本阳性率（24.83%）高于生活区（3.64%），差异有统计学意义（P . 592）
Background: Coronavirus disease 2019 (COVID-19) is characterized by risk of nosocomial transmission; however, the extent of environmental contamination and its potential contribution of environmental contamination to SARS-CoV-2 transmission are poorly understood. This study aimed to investigate whether environmental contamination may play a role in SARS-CoV-2 transmission.Methods: Air samples were collected by natural precipitation, and environmental surface samples were collected by conventional surface swabbing. SARS-CoV-2 RNA detection was performed using reverse transcription polymerase chain reaction.Results: Viral RNA was not detected in the 44 air samples. The positive rates in 200 environmental surface samples in medical areas (24.83%) was higher than that in living quarters (3.64%), with a significant difference (P
