More than 26.1 million Americans were estimated to be suffering from asthma in 2018, including 19.9 million adults and 6.2 million children. The negative health impacts of this chronic condition are immense, costing the United States more than $80 billion per year. Asthma is a complex, chronic inflammatory disorder of the airways. Its causes are poorly understood and multi-factorial, with risk factors varying in different populations. While there is no cure for the disease, symptoms can be effectively controlled with a combination of appropriate medical care, health education, and reduction or elimination of exposure to asthma triggers and respiratory irritants.
