Abstract
AbstractThe air quality of enclosed spaces has attracted great attention due to the ongoing Covid-19 pandemic. The infection risk in these spaces can be estimated for various scenarios with different methods so the important parameters and effective infection prevention measures can be compared. Previous studies showed that indoor CO2 concentration could be considered a surrogate for infection risk. In this regard, a generic relation can be established between the CO2 levels and infection probability. Based on this consideration, some practical evaluations between CO2 concentration and infection risk are conducted in this study. The effect of mask efficiency, viral emission rate, and duration of exposure are also included in the assessments. It is shown that continuous CO2 monitoring can be helpful in the evaluation of possible preventive measures. Findings are expected to contribute to the understanding of the simple parameters related to the infection risk.
