Topic:

  • [Pre-print, not peer reviewed] Simulation modeling based on fluid dynamics models and mouse experimental models was used to estimate that the median infection risk of contracting SARS-CoV-2 via aerosol exposure for one hour was more than three orders of magnitude lower than the risk due to close contact (13% based on a meta-analysis).
