Respiratory disorders are the
most common causes of illness and hospitalization in
children. These illnesses range from mild, non-acute disorders (such as the common cold or sore throat), to acute
disorders (such as bronchiolitis), to chronic conditions
(such as asthma), to serious life-threatening conditions
(such as epiglottitis). Chronic disorders, such as allergic
rhinitis, can affect quality of life, but frequent acute or
recurrent infections also can interfere significantly with
quality of life for some children.
