The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and resulting COVID-19 (coronavirus disease 2019) pandemic have required mass diagnostic testing, often taking place in testing sites within hospitals, clinics, or at satellite locations. To establish the potential of SARS-CoV-2 aerosol transmission and to identify junctures during testing that result in increased viral exposure, aerosol and surface samples were examined for the presence of SARS-CoV-2 RNA from locations within Nebraska Medicine COVID-19 testing and vaccine clinics. Aerosols containing SARS-CoV-2 RNA detected within clinics suggest viral shedding from infected individuals. SARS-CoV-2 RNA detection in aerosol samples was shown to correlate with clinic operation and patient infection, as well as with community infection findings. Additionally, SARS-CoV-2 RNA was detected in surface samples collected from clinics. The presence of SARS-CoV-2 RNA in aerosols in these clinics supports the continued use of respiratory protection and sanitization practices for healthcare workers, and other workers with public facing occupations.
严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）和由此产生的 COVID-19（2019 年冠状病毒病）大流行需要进行大规模的诊断检测，通常在医院、诊所内的检测点或卫星地点进行。为了确定 SARS-CoV-2 气溶胶传播的潜力，并确定检测过程中导致病毒暴露增加的环节，从内布拉斯加大学医学中心 COVID-19 检测和疫苗接种诊所内的位置采集了气溶胶和表面样本，以检测 SARS-CoV-2 RNA 的存在。从诊所内检测到含有 SARS-CoV-2 RNA 的气溶胶表明感染个体有病毒脱落。气溶胶样本中 SARS-CoV-2 RNA 的检测结果与诊所的运作、患者的感染以及社区感染的发现相关。此外，还从诊所收集的表面样本中检测到了 SARS-CoV-2 RNA。这些诊所中气溶胶中存在 SARS-CoV-2 RNA 支持继续为医护人员和其他面向公众的职业的工作人员使用呼吸道保护和消毒措施。
