Asthma is a complex respiratory disease characterized by inflammation and reversible obstruction of the airways that can lead to diverse symptoms such as wheeze, breathlessness, chest tightness, and cough. Asthma affects approximately 350 million people from all age groups worldwide and causes around 350,000 deaths per year. Approximately 45% of infants have one episode of wheezing in their first year of life, and about 20% have recurrent wheezing.
