The world is currently facing an unprecedented healthcare crisis caused by a pandemic novel beta coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The pathogen is spread by human-to-human transmission via droplets exposure and contact transfer, causing mild symptoms in the majority of cases, but critical illness, bilateral viral pneumonia, and acute respiratory distress syndrome (ARDS) in a minority. Currently, controlling infection to prevent the spread of SARS-CoV-2 is the primary public healthcare intervention used. The pace of transmission and global scale of SARS-CoV-2 infections has implications for strategic oversight, resource management, and responsiveness in infection control. This article presents a summary of learning points in epidemiological infection control from the SARS epidemic, alongside a review of evidence connecting current understanding of the virologic and environmental contamination properties of SARS-CoV-2. We present suggestions for how personal protective equipment policies relate to the viral pandemic context and how the risk of transmission by and to anaesthetists, intensivists, and other healthcare workers can be minimised.
目前,全球正面临由新型β冠状病毒——严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)引起的空前医疗保健危机。该病原体通过飞沫暴露和接触传播在人与人之间传播,导致大多数情况下症状轻微,但少数情况下会出现重症、双侧病毒性肺炎和急性呼吸窘迫综合征(ARDS)。目前,控制感染以防止 SARS-CoV-2 传播是主要的公共卫生保健干预措施。SARS-CoV-2 的传播速度和全球感染规模对战略监督、资源管理和感染控制的响应能力具有重要意义。本文总结了 SARS 疫情期间在流行病学感染控制方面的学习要点,并回顾了目前对 SARS-CoV-2 的病毒学和环境污染特性的认识。我们提出了有关个人防护设备政策与病毒大流行背景的关系的建议,以及如何将麻醉师、重症监护医生和其他医护人员的传播风险降至最低。
