Asthma is a serious chronic lung disease where the airways are always somewhat inflamed. During episodes or attacks, they become increasingly inflamed, often in response to specific triggers.
Asthma affects 24.8 million Americans, including 5.5 million children, and accounts for millions of emergency department visits and tens of billions in healthcare costs each year. This report presents descriptions, figures, and links to more detailed tables on trends and current patterns of the burden of asthma among adults and children.
