新型冠状病毒肺炎疫情期间密闭空间卫生防护问题探讨

Discussion of Related Issues on Health Protection in Confined Spaces during COVID-19 Pandemic

摘要: 飞沫传播和接触传播是新型冠状病毒（SARS-CoV-2）的主要传播途径，在相对密闭的环境中长时间暴露于高浓度气溶胶情况下，存在经气溶胶传播的可能。本文按照场所是否与外界有通风换气对密闭空间分进行分类，围绕新冠病毒在密闭空间中的传播特点，进行分析并提出卫生防护措施。

Abstract: Droplet transmission and contact transmission are the most important routes of transmission for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The possibility of aerosol transmission may exist if exposuring to a high concentration of aerosol in a relatively closed environment for a long time. This article classifies confined space according to whether the place has ventilation with the outside, and proposes health protection measures based on the characteristics of SARS-CoV-2 transmission in confined space.
