Asthma is a serious, sometimes life-threatening respiratory disease that affects the quality of life for millions of Americans. Asthma leads to 2 million emergency room visits and 5,000 deaths per year in the U.S. And although many cases of asthma go undiagnosed, health officials estimate that at least 20 million people in the U.S. have asthma, including 6.3 million children. Although there is no cure yet, it can be controlled through medical treatment and management of environmental "triggers".
