我们测量气溶胶持久性,以评估严重急性呼吸道综合征冠状病毒2(SARS-CoV-2)在公共场所传播的风险。然而,直接测量气溶胶浓度已被证明在技术上是困难的;我们建议使用手持式颗粒计数器作为一种新颖且易于应用的方法来测量气溶胶浓度。这使我们能够在典型的公共空间中进行测量,每个公共空间的体积,人数和通风率都不同。这些数据用于估计气溶胶持续时间与SARS-CoV-2感染风险之间的关系。
We measure aerosol persistence to assess the risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in public spaces. Direct measurement of aerosol concentrations, however, has proven to be technically difficult; we propose the use of handheld particle counters as a novel and easily applicable method to measure aerosol concentrations. This allows us to perform measurements in typical public spaces, each differing in volume, the number of people, and the ventilation rate. These data are used to estimate the relation between the aerosol persistence time and the risk of infection with SARS-CoV-2.
