Indoor fungal diversity in primary schools may differently influence allergic sensitization and asthma in children
Apart from home, young children spend a large section of their daytime at school, mostly within their classrooms, which might be reflected as a long‐term exposure to indoor air microbes 5. If the human microbiome does change according to environmental exposure, the classroom environment might contribute to microbiome changes and, consequently, either induce the development and/or exacerbation of allergy and asthma or, on the other hand, have a protective effect against their onset.
Therefore, the aim of this cross‐sectional study was to observe how the prevalence of allergic sensitization and asthma in schoolchildren is influenced by the exposure to indoor air bacteria and fungi in classrooms. More specifically, this work aimed to (i) quantify the concentration of microbiologic parameters in the indoor air of primary school classrooms; and (ii) investigate how microbial concentrations and diversity may influence the risk of asthma and allergy in primary school children.
