Anaphylaxis due to a mold allergy is extremely rare, but a mold allergy could cause a severe respiratory reaction if the patient has allergic bronchial asthma due to mold sensitivity. How much mold allergy contributes to mortality in asthma patients is unknown.

Morbidity associated with mold allergy is high in pediatric population because most children develop allergic symptoms early in their lives following exposure to mold allergens.

Although the patient number is limited, those who develop ABPA, ABPM, AFS, or EAA generally experience chronic, relapsing clinical courses. These patients must be aggressively treated during relapse. When ABPA, ABPM, hypersensitive pneumonitis, or EAA is not well controlled, it can result in substantial disability or even death.

The frequency of prolonged coldlike symptoms in winter, sinusitis, and adenoid hypertrophy is higher among the children who have mold allergy than those without mold allergy.
