A cross-sectional survey was conducted to assess allergic/asthmatic conditions in schoolchildren aged 6∼15 years old in 44 schools across Taiwan. Personal histories and current asthmatic conditions were collected. Fungal spores in classroom were collected using a Burkard Personal Air Sampler and counted under light microscopy.
The survey was completed by 6346 out of 7154 parents. The prevalences of physician-diagnosed asthma, current asthma, and asthma with symptoms reduced on holidays or weekend.
Classroom mold counts were significantly associated with childhood asthma and with reduced asthma symptoms on weekends. Government health policy should explore environmental interventions for the elimination of fungal spores in classrooms to reduce the prevalence of childhood asthma.
If your child has asthma, please call us for a simple allergy test to exclude mold and other allergies.
