Asthma is the most common chronic disease among children and is a public health concern not just for high-income countries; it occurs in all countries regardless of the level of development. 

What is Asthma? 

Asthma is a chronic inflammatory disease of the lungs in which the airways become blocked or narrowed causing breathing difficulty. Asthma is commonly divided into two types: allergic (extrinsic) asthma and non-allergic (intrinsic) asthma. It is characterized by sudden (e.g asthma attack) or persistent symptoms and is usually reversible, either spontaneously or with treatment. 

Asthma is the most common chronic disease among children and is a public health concern not just for high-income countries; it occurs in all countries regardless of the level of development. Asthma is under-diagnosed and under-treated. It creates substantial burden to individuals and families and often restricts an individual’s activities for a lifetime.
