No epidemiologic data are currently available. However, in recent years, mold exposure in schoolchildren has become a major concern of parents and healthcare professionals worldwide. The increase in mold allergy symptoms in susceptible children may be partly attributed to improper repair of moisture-damaged buildings or congested homes of the inner city.

An interesting observation was reported in Poland. [12] A survey of art conservators found that 85% of art conservators and museum workers reported allergic symptoms. Cladosporium, Alternaria, and yeasts were the species that played the most important role in the development of fungal hypersensitivity. A duration of occupational exposure of longer than 5 years, the presence of domestic animals (especially a cat at home), elevated total IgE level, allergic rhinitis, and skin sensitivity to common allergens (eg, grass pollens, mites) are significant risk factors for the development of hypersensitivity to fungi among those museum workers.
