Study shows indoor air contains greater diversity of airborne fungi than previously thought

Researchers from Imperial College London have conducted the U.K.'s largest-ever longitudinal study of indoor fungal air pollution, revealing that homes are active fungal ecosystems rather than passive recipients of outdoor air. The West London Healthy Home and Environment Study (WellHome), led by researchers from Imperial's School of Public Health, analyzed the air in 118 households over a two-year period. The study focuses on children with asthma or allergies and families from ethnic minority groups and lower socio-economic backgrounds.
