But nobody really knows why.
Approximately 25 million Americans (1 in 12) have asthma. And that figure is rising despite efforts to reduce it by controlling asthma triggers such as indoor smoking.
Said Paul Garbe, chief of the CDC's Air Pollution and Respiratory Health Branch:
"Despite the fact that outdoor air quality has improved, we've reduced two common asthma triggers - secondhand smoke and smoking in general — asthma is increasing. While we don't know the cause of the increase, our top priority is getting people to manage their symptoms better."
Instances of asthma have increased among all groups of people, but children were affected worse than others. And additional 4.3 million people were diagnosed between 2001 and 2009.
Said CDC Director Dr. Thomas Frieden:
“Asthma is a serious, lifelong disease that unfortunately kills thousands of people each year and adds billions to our nation's healthcare costs. We have to do a better job educating people about managing their symptoms and how to correctly use medicines to control asthma so they can live longer more productive lives while saving health care costs."
It’s a sad day for lungs everywhere…
