The three most prevalent diseases are:

Allergic bronchopulmonary Aspergillosis: Produces allergies, common in asthmatics and CF, similar symptoms to asthma. Invasive Aspergillosis: Often fatal, no good diagnostic test, very early treatment needed, usually present to people with health problems, fever and lung symptoms. Bronchoscopy helps diagnosis. Pulmonary Aspergilloma: grow within lung cavity, spores penetrate the cavity and germinate, may have no symptoms, x-ray diagnosis.
