Allergy-triggered asthma is a type of asthma commonly seen in children. Symptoms
of asthma in these children are brought on by allergic reactions to things such as
dust mites, pollen, or animal dander. Although not all asthma is triggered by allergies,
and not all allergies cause symptoms of asthma, an estimated 75% to 85% of children
with asthma have some type of allergy.
