Molds are ubiquitous microorganisms; therefore, unless the prevalence of the offending fungi is known, eliciting a history of fungal exposure leading to chronic inflammation and disease development is difficult.

In EAA, because of the relationship between the disease and exposure to specific fungi in particular professions, the diagnosis can be suspected at an early stage. The period from exposure to onset of disease may be months to years in EAA.

The frequency of familiar occurrence of ABPA was determined in 164 patients with ABPA diagnosed over a period of 22 years in one study. [17] The familiar occurrence of ABPA was found only in 4.9% of the 164 patients.
