Because molds can grow in indoor environments, many children are exposed to them from birth. How early children can become allergic to mold Ags is unclear; however, nearly 40% of children with allergic rhinitis have positive skin test or radioallergosorbent testing (RAST) reactivity to mold allergens.

Symptoms of allergic rhinitis include runny nose, itchy nose, sneezing, nasal congestion, sniffling, sore throat, cough, itchy eyes, and runny eyes and may be worse when patients are indoors. Symptoms may be most severe in hot and humid seasons, but some molds are prevalent throughout the year. The most characteristic symptoms are injected conjunctivae, headache, and fatigability.

Children typically have a history of recurrent respiratory infections (including sinus infections) and otitis media.

One study revealed that mold allergy may be most prevalent in winter secondary to the airtight insulation used in homes built in recent years. [15, 16] History of prolonged cold symptoms that last for more than 2 weeks in winter may indicate mold allergy.

Although uncommon, sinusitis or lower respiratory tract disease (eg, allergic bronchitis, bronchial asthma) subsequently develops in some patients.

An increased prevalence of adenoid hypertrophy is reported in children with mold allergy.
