Causes, incidence, and risk factors:

Epiglottitis is most common in children between 2 and 6 years old and is usually caused by the bacterium Haemophilus influenzae, although it may be caused by other bacteria or viruses. Although rare, epiglotitis can occur in normal adults. Because it is rare in adults, it may be easily overlooked as a diagnosis. The condition can progress rapidly. In the US, the incidence of this disease has decreased steadily since Haemophilus influenzae type B (Hib) vaccine became a routine childhood immunization in the late 1980s.

Epiglottitis is a life-threatening disease that begins with a high fever and very sore throat. The epiglottis (the flap of cartilage at the back of the tongue that closes off the windpipe when swallowing) swells and can obstruct breathing. Respiratory distress increases rapidly as the epiglottis swells.

Immunosuppression (from medications or diseases that reduce the action of the immune system) can predispose adults to epiglottitis.

Swallowing problems may be associated with drooling. Breathing difficulty may cause the patient to sit up, leaning slightly forward and looking very anxious. Spasm may cause the airway to close abruptly. In this case, death follows within minutes. Do not make any attempts to look into the patient's mouth if epiglottitis is suspected.
