Airborne Transmission of SARS-CoV-2 – A Nebulous Pathway to Infection

There is growing evidence that SARS-CoV-2 can be spread through longer range aerosol particle transmission, in addition to near-field droplet and fomite transmission. The airborne transmission pathway is characterized by the emission of virus-laden aerosol particles, produced during speaking and breathing, that can be easily dispersed indoors. In this presentation, Dr. Tim Bertram, Professor of Chemistry and Associated Professor of Atmospheric and Oceanic Sciences, reviews recent experiments focused on airborne transmission of SARS-CoV-2 in typical classrooms and discusses engineering and behavioral intervention strategies to reduce the risk of infection.
