BACKGROUND
Healthcare workers in obstetric clinics may be exposed to airborne SARS-CoV-2 when treating patients with COVID-19.
METHOD
In this study, performed during the midst of the pandemic, air samples were collected in delivery rooms during childbirth and analysed for SARS-CoV-2 RNA content.
RESULT
Six of 28 samples collected inside delivery rooms were positive for SARS-CoV-2, but none in anterooms or corridors. Five of the six positive samples were from the same occasion.
DISCUSSION
This indicates that some patients could be major sources of exhaled virus, although the individual variation is large, and it is thus difficult to predict the risk of infection.
背景
产科诊所的医护人员在治疗新冠肺炎患者时可能会接触到空气传播的严重急性呼吸综合征冠状病毒2（SARS-CoV-2）。
方法
在疫情期间进行的这项研究中，在分娩期间于产房采集空气样本，并分析其SARS-CoV-2 RNA含量。
结果
在产房内采集的28个样本中有6个SARS-CoV-2呈阳性，但在前厅或走廊采集的样本均为阴性。6个阳性样本中有5个来自同一时段。
讨论
这表明一些患者可能是呼出病毒的主要来源，尽管个体差异很大，因此很难预测感染风险。
