Despite previous studies reporting the health effects of exposure to both chemical and (micro)biological agents, aeroallergens have been less well studied. Most studies have focused on exposure to indoor allergens at home. However, exposure can happen in other environments, including in schools where children spend much of their time. Review questions: What are the most common indoor allergens in schools? What methods (sampling and assays) are applied to measure the levels of indoor allergens in schools? What are the levels of indoor allergens in schools? What are the determinants of indoor allergens in schools? Which areas of schools have the highest levels of allergens (e.g., wet areas/bathrooms)? What are the effects of exposure to indoor allergens on asthma, asthma-like symptoms, asthma control, allergic sensitization, and allergic diseases?info:eu-repo/semantics/publishedVersio
