Quantitative Microbial Risk Assessment for Airborne Transmission of SARS-CoV-2 and the Efficacy of Ultraviolet Germicidal Irradiaton (UVGI) Systems

<p>To assess the performance of both treatment on reducing the infection risk, this study developed the Indoor Air Quality (IAQ) model that simulates the dynamics of airborne infective SARS-CoV-2 in a 500 m3 with or without mechanical ventilation and UV system. Then this model was linked to a quantitative microbial risk assessment (QMRA) to allow for estimation of the risk of disease transmission for a given treatment condition.</p>
