CO₂ concentration as an indicator of indoor ventilation performance to control airborne transmission of SARS-CoV-2.

ABSTRACT:

Background

The Wells-Riley equation has been extensively used to quantify the infection risk of airborne transmission indoors. This equation is difficult to apply to actual conditions because it requires measurement of the outdoor air supply rate, which vary with time and are difficult to quantify. The method of determining the fraction of inhaled air that has been exhaled previously by someone in a building using a CO₂ concentration measurement can solve the limitations of the existing method. Using this method, the indoor CO₂ concentration threshold can be determined to keep the risk of infection below certain conditions.

Methods

Based on the calculation of the rebreathed fraction, an appropriate mean indoor CO₂ concentration and required a
