How common is asthma in children?
Asthma is the most common chronic disease of childhood. The prevalence of asthma is increasing. This is also the case with other allergy conditions, including eczema (atopic dermatitis), hay fever (allergic rhinitis), and food allergies. According to recent CDC data, asthma affects approximately 8.5% of the pediatric population in the U.S., or more than 7 million children. Asthma accounts for more school absences and more hospitalizations than any other chronic condition in this country.
