Health by the Numbers: Asthma
Asthma is a chronic lung disease that inflames and narrows the bronchial airways, causing recurring wheezing, chest tightening, shortness of breath, and coughing. It typically begins in childhood and persists into adulthood. Asthma is common, according to the Centers for Disease Control (CDC), in 2010 almost 19 million adults and seven million children had asthma.
Here's a look at a few asthma statistics:
