Epidemiology of allergic bronchopulmonary aspergillosis

Despite worldwide reports, ABPA has not attained inclusion into the International Classification of Diseases, making epidemiological data difficult to gather. Lack of uniform diagnostic standards has also impeded the collection of accurate prevalence rates. Best estimates obtained from literature searches and surveys indicate less than a 1% prevalence in asthma and about a 7% prevalence in CF for ABPA. Mortality rates appear to be exceedingly low A perceived decline of patients with ABPA under specialist supervision suggests a decrease in new case discovery.
