Croup (or laryngotracheobronchitis)

Croup (or laryngotracheobronchitis) is a respiratory condition that is usually triggered by an acute viral infection of the upper airway. It normally lasts one to two days.[1] The infection leads to swelling inside the throat, which interferes with normal breathing and produces the classical symptoms of a "barking" cough, stridor, and hoarseness. It may produce mild, moderate, or severe symptoms, which often worsen at night. It is often treated with a single dose of oral steroids; occasionally inhaled epinephrine is used in more severe cases. Hospitalization is rarely required.
Croup is diagnosed on clinical grounds, once potentially more severe causes of symptoms have been excluded (i.e. epiglottitis or an airway foreign body). Further investigations—such as blood tests, X-rays, and cultures—are usually not needed. It is a relatively common condition that affects about 15% of children at some point, most commonly between 6 months and 5–6 years of age. It is almost never seen in teenagers or adults.
Before the advent of vaccination, croup was frequently caused by diphtheria, and was often fatal. This cause is now a historical one in the Western world due to the success of the diphtheria vaccine and improved hygiene and living standards.[2]
