Association of ventilation mode and indoor CO2 concentration with indoor fungal communities in Singapore childcare centers

Abstract

As society has progressed, there has been a shift from people working outdoors to indoors, and it is now estimated that the average person spends 90% of their time indoors. With this shift, there is an increased importance for the study of indoor air quality, in particular microbiome environment with a focus on the fungi species found indoors as it pertains to the general public’s health and safety. This is due to the potential for pathogenic species to enter the indoor spaces and cause harm to the general public. Due to this, we aim to investigate and study the association of the ventilation modes and their respective indoor CO2 concentration with the fungal microbiome composition, and we hypothesize that the indoor fungal microbiome composition is associated with the ventilation mode and indoor CO2 level.
